| CVE-2026-98143 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: accel: ethosu: Don't read the U65 rounding mode as a storage mode Bits 15:14 of NPU_SET_{IFM,OFM}_PRECISION select the activation storage mode on U85 only. On U65 the same field holds the rounding mode, and the command stream parser has read it as a storage mode since the driver was added. That went unnoticed while unknown values fell through the switch, but now that they are rejected, every U65 command stream that asks for natural rounding (2) fails CMDSTREAM_BO_CREATE with -EINVAL. Mesa emits it for average pooling, concatenation, split, unpack, strided slice, LUT and argmax, which is 72 failures of the Teflon test suite on an i.MX93. Truncating rounding (1) is misread as well: it picks the two-tile address path and computes a bogus feature map size from tile bases the command stream never set. Read the field as a storage mode only on the hardware where it is one. | ||||
| CVE-2026-97578 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: media: verisilicon: rockchip: guard VPU981 AV1 divisor and tile buffer rockchip_vpu981_av1_dec_set_tile_info() divides context_update_tile_id by tile_info->tile_cols and writes one descriptor per tile into the tile_info DMA buffer, which holds AV1_MAX_TILES entries; tile_cols and tile_rows come from the bitstream. Guard the division against a zero tile_cols by initialising the context-update values to zero and computing them only when tile_cols is non-zero, and stop the descriptor writes once the tile_info buffer is full. The tile geometry written to the hardware registers is left unmodified; the per-dimension and total tile bounds are enforced by the control validation. | ||||
| CVE-2026-97579 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: media: mediatek: vcodec: bound AV1 tile-start copy to the array capacity vdec_av1_slice_setup_tile() copies tile_cols + 1 / tile_rows + 1 entries into mi_col_starts[] / mi_row_starts[] from the bitstream tile_info. Bound the copy to the array capacity. | ||||
| CVE-2026-97612 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: net: mpls: clear inner_protocol when the last label is popped skb_mpls_push() records the pre-encapsulation network header once, gated on !skb->inner_protocol. skb_mpls_pop() never clears that record, so it outlives the encapsulation it describes. Open vSwitch can then re-push MPLS onto a packet whose inner_network_header still points at the older, deeper offset: push a label, pop every label, recirculate (ovs_flow_key_update() re-derives key->eth.type and resets network_header, but leaves inner_*), then push again. ovs_fragment() trusts the record: skb->network_header = skb->inner_network_header; so skb_network_offset() goes negative. The bound check is signed: if (skb_network_offset(skb) > MAX_L2_LEN) a negative offset passes it, and prepare_frag() widens the value: unsigned int hlen = skb_network_offset(skb); memcpy(&data->l2_data, skb->data, hlen); which is a ~4GiB memcpy out of a 30-byte per-CPU buffer. Reproduced on v7.3-rc1. RDX is the truncated length, (unsigned int)(-8): BUG: unable to handle page fault for address: ffffe8ffffc16000 #PF: supervisor write access in kernel mode Oops: 0002 [#1] SMP KASAN NOPTI RIP: 0010:memcpy+0x8/0x20 RDX: 00000000fffffff8 RSI: ffff888105d732db RDI: ffffe8ffffc16000 prepare_frag+0x3df/0x4e0 ovs_fragment+0x589/0x7e0 do_output+0x4ce/0x5e0 do_execute_actions+0x55d2/0x7b30 ovs_execute_actions+0xea/0x450 Same root-cause shape as commit 975b5b067f52 ("ipv6: sr: restore network header before routing and forwarding"): a stale network header offset reaching a consumer that widens it. Here it originates in the MPLS push/pop path. Clear inner_protocol once the packet is no longer MPLS, so a later push re-records the current header. net/sched/act_mpls.c is the only other skb_mpls_pop() caller and gets the same fix; sch_frag.c saves and restores inner_protocol around fragmentation in the same way OVS does. | ||||
| CVE-2026-97621 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: drm/rockchip: analogix_dp: fix unchecked bound endpoint name length rockchip_dp_drm_encoder_enable() uses sprintf() to format a device tree path into a 32-byte stack buffer. Device tree paths are not limited to this size, so a sufficiently long path can overflow the buffer. Use snprintf() with the destination size to truncate the generated name and keep the writes within bounds. | ||||
| CVE-2026-97910 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: ASoC: sprd: validate compress buffer sizes against fixed allocations sprd_platform_compr_open() allocates the stage 0 IRAM buffer (32K data area) and the stage 1 DDR buffer (2M data area) with fixed sizes, but sprd_platform_compr_copy() derives all copy lengths from the user controlled runtime->fragment_size and the write() count, never comparing them against the physical buffer sizes. The compress core only checks fragment_size * fragments for an u32 overflow in snd_compress_check_input(), so a local user can configure a logical buffer of up to ~4GB via SNDRV_COMPRESS_SET_PARAMS, far exceeding the fixed allocations. A fragment_size larger than the 32K IRAM data area makes the stage 0 copy_from_user() overflow past the IRAM allocation, and a buffer_size larger than the 2M DDR buffer makes the wrapping copy at the end of sprd_platform_compr_copy() write fully user controlled data past the buffer. No SNDRV_PCM_TRIGGER_START is needed, a write() in SETUP state reaches the copy callback directly. Reject parameters that do not fit into the fixed buffers in set_params(), and fix the advertised max fragment size: 128K never fitted into the 32K IRAM buffer. The caps values may have been carried over from the qdsp6 driver, which allocates its buffers according to the advertised maxima, unlike this driver. With 32K as max fragment size the advertised limits are self-consistent: 32K * 64 = 2M equals the DDR buffer size. Discovered by Atuin - Automated Vulnerability Discovery Engine. | ||||
| CVE-2026-97957 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: net: hinic: fix mailbox segment buffer overflow check_mbox_seq_id_and_seg_len() validates that seq_id does not exceed SEQ_ID_MAX_VAL (42) and seg_len does not exceed MBOX_SEG_LEN (48). However, this allows the last segment (seq_id=42) to carry a full 48-byte payload, writing to offset 42*48=2016 for 48 bytes (ending at byte 2064). The receive buffer is only MBOX_MAX_BUF_SZ (2048) bytes, resulting in a 16-byte heap buffer overflow. The hinic3 driver already handles this correctly by defining MBOX_LAST_SEG_MAX_LEN and rejecting the last segment when it exceeds the remaining buffer space. Apply the same fix to the hinic driver. | ||||
| CVE-2026-97581 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: media: verisilicon: hantro: bound G2 HEVC tile loop to the buffer capacity prepare_tile_info_buffer() writes one entry per tile into the tile_sizes DMA buffer, sized for a grid equal to the PPS uAPI array capacity. Use the bounded v4l2_hevc_pps_num_tile_columns() / v4l2_hevc_pps_num_tile_rows() helpers so the loops stay inside the buffer. | ||||
| CVE-2026-97994 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: vhost/vdpa: reject VRING_NUM larger than device max vhost_vring_set_num() accepts any non-zero power-of-two queue size that fits in 16 bits. vhost-vdpa then passes that value to set_vq_num() without comparing it with get_vq_num_max(). A process with access to /dev/vhost-vdpa-* can therefore configure a queue larger than the device advertises. With vdpa_sim, the worker can walk descriptors beyond the mapped descriptor ring. KASAN reports a 16-byte out-of-bounds read, corresponding to one vring_desc, in the vringh IOTLB path: BUG: KASAN: out-of-bounds in _copy_from_iter Read of size 16 copy_from_iotlb copydesc_iotlb vringh_getdesc_iotlb vdpasim_net_work Cache get_vq_num_max() immediately after reset. Some backends derive it from writable queue-size state, so querying it after SET_NUM may return the current size instead of the device capability. Invalidate the cached value before reset so a failed reset leaves SET_NUM disabled. For VHOST_SET_VRING_NUM, copy the complete vring state once and use the same index and size for validation, vq->num, and set_vq_num(). This ensures that validation and use operate on the same copied values. | ||||
| CVE-2026-97995 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: virtio_console: do not free control-out buffers on remove __send_control_msg() publishes &portdev->cpkt as the control-out virtqueue cookie. remove_vqs() walks every virtqueue and passes leftover cookies to free_buf(), which treats them as struct port_buffer and reads sgpages. If a control message is still on c_ovq when the device is unbound, free_buf() reads past the ports_device object. KASAN reported slab-out-of-bounds in free_buf(): free_buf remove_vqs virtcons_remove unbind_store The object was the ports_device allocated in virtcons_probe(). Drain c_ovq without freeing. The packet lives in portdev and is released with it. | ||||
| CVE-2026-98085 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: bpf: backtrack_insn(): Handle ld_{abs,ind} subprog exit edge Nicholas Carlini reported a bug in precision backtracking mechanism for BPF_LD | BPF_{IND,ABS} instructions. These instructions are modelled as two branches: - fallthrough; - implicit exit from current subprogram. The implicit exit case was not handled by the backtrack_insn() function. When backtracking such a path backtrack_insn() did not call bt_subprog_enter(), which meant that backtracking continued manipulating precision marks in a caller frame, while looking at instructions in a callee frame. This lead to segmentation faults during verification (see the selftest), or unsound state pruning. | ||||
| CVE-2026-100078 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mei: pass correct argument to function The first argument to iwl_mei_write_cyclic_buf() should be the cldev but the q_head pointer is passed instead. Fix it. | ||||
| CVE-2026-97565 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: smb: client: reject short READ responses in CIFSSMBRead() CIFSSMBRead() reads DataLengthHigh, DataLength and DataOffset out of the READ_RSP returned by the server without first checking that a whole READ_RSP was actually received. The length of the response is recorded in rsp_iov.iov_len, but nothing constrains it to be at least read_rsp_size before those fields are dereferenced. A malicious or compromised SMB1 server can return a response shorter than the READ_RSP header, so that parsing the header itself reads past the end of the receive buffer. SMB1 is not negotiated by default; reaching this code requires an explicit vers=1.0 mount. Reject the response unless it is at least read_rsp_size bytes long. | ||||
| CVE-2026-20136 | 1 Cisco | 3 Identity Services Engine, Identity Services Engine Passive Identity Connector, Identity Services Engine Software | 2026-09-25 | 6 Medium |
| A vulnerability in the CLI of Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, local attacker with administrative privileges to perform a command injection attack on the underlying operating system and elevate privileges to root. This vulnerability is due to insufficient validation of user supplied input. An attacker could exploit this vulnerability by providing crafted input to a specific CLI command. A successful exploit could allow the attacker to elevate their privileges to root on the underlying operating system. | ||||
| CVE-2026-98078 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ipvs: fix reversed sequence option serialization hton_seq() expects the host-order source first and the unaligned network-order destination second. The version 1 sync sender passes these arguments in reverse for both sequence blocks. This leaves 24 bytes of the kmalloc-backed message unwritten. It may disclose stale heap data and replace the live connection sequence state with values read from the buffer. Pass the connection sequence state as the source and the message payload as the destination for both blocks. | ||||
| CVE-2026-98159 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: validate CLC firmware records The CLC region is supplied by firmware, but the loader trusts the region count and each record length. A malformed image can make the region table pointer precede the firmware buffer, make the record loop fail to advance, or index phy->clc past its end. Validate the table and record bounds before dereferencing or copying. | ||||
| CVE-2026-97535 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Bound VP index against VP_CTRL IOCB bitmap size The VP control IOCB selects its target virtual port by setting one bit in vp_idx_map, a fixed 16-byte (128-bit) array in both vp_ctrl_entry_24xx and vp_ctrl_entry_24xx_ext. qla25xx_ctrlvp_iocb() computes map = (vp_index - 1) / 8 and writes vce->vp_idx_map[map] without checking that map stays within the array. max_npiv_vports is taken from firmware and only sanitized to a MIN_MULTI_ID_FABRIC-aligned boundary, so it can legitimately be 191 or 255, and qla24xx_control_vp() only rejects vp_index >= max_npiv_vports. A vp_index above 128 therefore yields map >= 16 and an out-of-bounds write of up to 16 bytes past vp_idx_map, corrupting the trailing IOCB fields (or the adjacent request-ring slot on the 64-byte layout). Reject a vp_index that cannot be represented in the IOCB bitmap in qla24xx_control_vp(), and add a defensive ARRAY_SIZE() guard in qla25xx_ctrlvp_iocb() before the write. Adapters that report the usual 63 or 127 NPIV vports are unaffected. | ||||
| CVE-2026-97964 | 1 Linux | 1 Linux Kernel | 2026-09-25 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ppp_synctty: ensure a writeable skb header ppp_sync_txmunge() checks headroom before prepending the address and control bytes, but does not ensure that the skb header is writable. A received skb can reach this function through PPP channel bridging without passing through ppp_start_xmit(), which calls skb_cow_head(). For example, a PPPoE frame may share its buffer with a clone queued to an AF_PACKET socket. If it is bridged to a synchronous tty channel, the address/control bytes can overwrite data still visible to that socket. Use skb_cow_head() to ensure both sufficient headroom and a writable header. | ||||
| CVE-2026-97991 | 1 Linux | 1 Linux Kernel | 2026-09-25 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: vdpa_sim_blk: reject out-of-range sector starts vdpasim_blk_check_range() logs an invalid start sector but continues validating the request. The subsequent unsigned capacity subtraction can underflow and let an out-of-range buffer offset reach the data path. The invalid offset is used by three request paths. VIRTIO_BLK_T_OUT copies guest data to blk->buffer + offset through vringh_iov_pull_iotlb(), causing an out-of-bounds write in _copy_from_iter() or memcpy(). VIRTIO_BLK_T_IN copies from blk->buffer + offset to the guest through vringh_iov_push_iotlb(), causing an out-of-bounds read in _copy_to_iter(). VIRTIO_BLK_T_WRITE_ZEROES passes blk->buffer + offset to memset(), causing an out-of-bounds write. Reject starts at or beyond the capacity before the subtraction. Treat the capacity boundary as invalid because the IN and OUT paths round byte counts down to sectors for validation but later copy the original byte counts. A sub-sector request at the capacity boundary would otherwise still access past the end of the buffer. I found this bug myself, though the patch was written with AI assistance. | ||||
| CVE-2026-61784 | 1 Cstigler | 1 Node-xhtml-purifier | 2026-09-25 | 6.1 Medium |
| xhtml-purifier is a Node.js library to take in raw/unknown/untrusted HTML and output cleaned, purified, trusted HTML. Versions prior to 0.4.3 do not HTML-entity-encode attribute values when serializing its sanitized output. In attributeString() (XHTMLPurifier.js, around line 148) the attribute value is concatenated directly into a double-quoted attribute without encoding. As a result, an attacker-controlled value in any allowed attribute (class, style, title, alt, src, href) can include a double-quote character to break out of the attribute and inject an additional attribute, such as a JavaScript event handler (for example onmouseover or onerror). The injected handler survives sanitization and executes when the output is rendered, which is a sanitizer bypass leading to cross-site scripting. The fix in version 0.4.3 HTML-entity-encodes attribute values before serialization. | ||||
