| In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: fix counter type in iwl_fwrt_dump_error_logs
The loop counter 'count' was declared as u8 while num_pc is u32.
If firmware advertises more than 255 PC entries the counter wraps
back to zero and the loop never terminates potentially causing an
infinite loop or reading past the allocated pc_data array.
Change the declaration to u32 to match num_pc. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: haptic: don't write an uninitialized value to unhandled usages
fill_effect_buf() initializes value only for the four haptic usages
handled by its switch, but writes it to field->value[] for every usage.
An unhandled usage can therefore receive either an uninitialized value
or one left over from the previous usage. hid_output_report() then
serializes that value into the effect's report buffer.
Skip unhandled usages instead. This also matches switch_mode(), which
only updates fields it recognizes.
Found with Clang's -Wconditional-uninitialized. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: target: iscsi: Reserve a terminator byte for the login payload
iscsi_target_check_login_request() rejects a login PDU whose
DataSegmentLength exceeds MAX_KEY_VALUE_PAIRS, but the test is '>' and
login->req_buf is allocated with exactly MAX_KEY_VALUE_PAIRS
bytes. Since iscsit_get_login_rx() receives payload_length + padding
bytes, where
padding = ((-payload_length) & 3);
any payload_length from 8189 to 8192 fills the whole 8192 byte
buffer. The write stays in bounds, but no byte is left for a NUL
terminator.
The buffer is subsequently consumed as a C string. In the CHAP path
chap_check_algorithm() calls kstrdup(a_str), and extract_param() calls
strstr(in_buf, pattern) followed by strlen_semi(), none of which take a
length. convert_null_to_semi() additionally rewrites every embedded NUL
to ';', so even a payload made of well formed NUL separated key=value
records is left without a terminator. These walk past the end of the
object into adjacent slab memory. It is reachable by an unauthenticated
initiator against a portal configured for CHAP; when authentication is
not required iscsi_login_zero_tsih_s2() rewrites AuthMethod to None and
the CHAP path is never entered.
Allocate one extra byte. kzalloc() zeroes it and nothing ever writes to
it, as every writer copies to offset 0 for at most MAX_KEY_VALUE_PAIRS
bytes, so the buffer is always terminated. |
| In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8723bs: fix OOB read in rtw_action_frame_parse()
rtw_action_frame_parse() takes a frame_len parameter but never
actually checks it before indexing into the frame body:
const u8 *frame_body = frame + sizeof(struct ieee80211_hdr_3addr);
...
c = frame_body[0];
...
a = frame_body[1];
frame_body already points 24 bytes (sizeof(struct
ieee80211_hdr_3addr)) into frame, so reading frame_body[0] and
frame_body[1] requires frame_len >= 26. A management action frame
shorter than that (e.g. exactly 24 bytes, the minimum a malicious
peer can send) causes a 1-2 byte out-of-bounds read.
This is reachable from rtw_cfg80211_monitor_if_xmit_entry() and
cfg80211_rtw_mgmt_tx() in ioctl_cfg80211.c, both of which pass
attacker/user-influenced frame buffers and lengths straight through.
Add the missing length check before frame_body is dereferenced. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: nci: fix uninit-value in the RF discover/activated NTF handlers
nci_rf_discover_ntf_packet() and nci_rf_intf_activated_ntf_packet() each
parse a notification into an on-stack struct (nci_rf_discover_ntf /
nci_rf_intf_activated_ntf) that is not initialised. The RF
technology-specific parameters are only extracted when
rf_tech_specific_params_len is non-zero, so a notification that reports a
zero length leaves the rf_tech_specific_params union uninitialised - and
both handlers then pass it to nci_add_new_protocol(), which reads it:
- discover: nci_add_new_target() -> nci_add_new_protocol();
- activated: nci_target_auto_activated() -> nci_add_new_protocol().
nci_add_new_protocol() uses nfca_poll->nfcid1_len as both a branch
condition and a memcpy() length and copies nfcid1/sens_res/sel_res into
ndev->targets, which is later exposed to user space via NFC_CMD_GET_TARGET.
BUG: KMSAN: uninit-value in nci_add_new_protocol+0x624/0x6c0

Local variable ntf.i created at:
nci_ntf_packet+0xbc2/0x3c30
Zero-initialise both on-stack notifications so the union reads back as
zero when no technology-specific parameters are present. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: xilinx-trng - Remove crypto_rng interface
Implementing the crypto_rng interface has no purpose, as it isn't used
in practice. It's being removed from other drivers too. Just remove
it. This leaves hwrng, which is actually used.
Tagging with 'Cc stable' due to the bugs that this removes:
- xtrng_trng_generate() sometimes returned success even when it didn't
fill in all the bytes.
- It was possible for xtrng_trng_generate() and
xtrng_hwrng_trng_read() to run concurrently and interfere with each
other, as the locking code in xtrng_hwrng_trng_read() was broken. |
| In the Linux kernel, the following vulnerability has been resolved:
arm64: dts: renesas: ironhide: Describe inline ECC carveouts
The DBSC5 DRAM controller protects DRAM content using inline ECC.
The inline ECC utilizes areas of DRAM for its operation, which are
in the DRAM address range, but must not be accessed or modified.
Describe the inline ECC carveout areas used by the DBSC5 controller
on this hardware as reserved-memory, which must not be accessed.
Include DRAM areas which are unprotected by ECC as well, those are
parts of the DRAM which directly precede the ECC carveout.
In case of high DRAM utilization, unless the inline ECC carveouts
are properly reserved, Linux may use and corrupt the memory used
by the DBSC5 DRAM controller for inline ECC, which would lead to
the system becoming unstable. |
| In the Linux kernel, the following vulnerability has been resolved:
net: bridge: mrp: fix uninitialised bytes on the wire
br_mrp_alloc_test_skb() builds MRP test frames on an skb from
dev_alloc_skb(), which does not clear the linear data area. On the MRA
ring-role branch the sub-option TLV header is appended with
sub_tlv = skb_put(skb, sizeof(*sub_tlv));
sub_tlv->type = BR_MRP_SUB_TLV_HEADER_TEST_AUTO_MGR;
so sub_tlv->length is never written, and the two trailing alignment bytes
are appended with a bare skb_put() that does not clear them either. The
neighbouring oui and sub_opt regions are explicitly zeroed, so three
uninitialised bytes are left in every MRA MRP_Test frame that goes out.
Put the sub-option TLV header and the alignment padding in a single
skb_put_zero(), which clears both. The AUTO_MGR sub-TLV carries no
payload, so the zeroed length field is already the value it should have. |
| A vulnerability in the memory management handling for the Snort 3 Detection Engine of Cisco Secure Firewall Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the Snort 3 Detection Engine to restart.
This vulnerability is due to a logic error in memory management when a device is performing Snort 3 SSL packet inspection. An attacker could exploit this vulnerability by sending crafted SSL packets through an established connection to be parsed by the Snort 3 Detection Engine. A successful exploit could allow the attacker to cause a denial of service (DoS) condition when the Snort 3 Detection Engine unexpectedly restarts. |
| A vulnerability in the SSL VPN feature for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition.
This vulnerability is due to a logic error in memory management when the device is handling SSL VPN connections. An attacker could exploit this vulnerability by sending crafted SSL/TLS packets to the SSL VPN server of the affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. |
| A vulnerability in the Snort 2 and Snort 3 TCP and UDP detection engine of Cisco Firepower Threat Defense (FTD) Software for Cisco Firepower 2100 Series Appliances could allow an unauthenticated, remote attacker to cause memory corruption, which could cause the Snort detection engine to restart unexpectedly.
This vulnerability is due to improper memory management when the Snort detection engine processes specific TCP or UDP packets. An attacker could exploit this vulnerability by sending crafted TCP or UDP packets through a device that is inspecting traffic using the Snort detection engine. A successful exploit could allow the attacker to restart the Snort detection engine repeatedly, which could cause a denial of service (DoS) condition. The DoS condition impacts only the traffic through the device that is examined by the Snort detection engine. The device can still be managed over the network.
Note: Once a memory block is corrupted, it cannot be cleared until the Cisco Firepower 2100 Series Appliance is manually reloaded. This means that the Snort detection engine could crash repeatedly, causing traffic that is processed by the Snort detection engine to be dropped until the device is manually reloaded. |
