| Use-after-free in the DOM: HTML Parser component. This vulnerability was fixed in Firefox 160, Firefox ESR 115.45, Firefox ESR 153.7, Thunderbird 160, and Thunderbird 153.7. |
| Use-after-free in the Graphics: Canvas2D component. This vulnerability was fixed in Firefox 160, Firefox ESR 115.45, Firefox ESR 153.7, Thunderbird 160, and Thunderbird 153.7. |
| In the Linux kernel, the following vulnerability has been resolved:
f2fs: atomic: fix UAF issue on f2fs_inode_info.atomic_inode
- ioctl(F2FS_IOC_GARBAGE_COLLECT_RANGE) - shrink
- f2fs_gc
- gc_data_segment
- ra_data_block(cow_inode)
- mapping = F2FS_I(inode)->atomic_inode->i_mapping
: f2fs_is_cow_file(cow_inode) is true
- f2fs_evict_inode(atomic_inode)
- clear_inode_flag(fi->cow_inode, FI_COW_FILE)
- F2FS_I(fi->cow_inode)->atomic_inode = NULL
...
- truncate_inode_pages_final(atomic_inode)
- f2fs_grab_cache_folio(mapping)
: create folio in atomic_inode->mapping
- clear_inode(atomic_inode)
- BUG_ON(atomic_inode->i_data.nrpages)
We need to add a reference on fi->atomic_inode before using its mapping
field during garbage collection, otherwise, it will cause UAF issue. |
| Use-after-free in the Graphics: Text component. This vulnerability was fixed in Firefox 159, Thunderbird 159, Firefox ESR 153.7, and Thunderbird 153.7. |
| Sandbox escape due to use-after-free in the XPCOM component. This vulnerability was fixed in Firefox 159, Thunderbird 159, Firefox ESR 153.7, and Thunderbird 153.7. |
| Use-after-free in the JavaScript: GC component. This vulnerability was fixed in Firefox 159, Thunderbird 159, Firefox ESR 153.7, and Thunderbird 153.7. |
| FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, peer_find_template() in src/netflow_plugin/netflow_collector.cpp and src/netflow_plugin/netflow_v9_collector.cpp returns a pointer into global_netflow9_templates after releasing the cache mutex. On deployments with at least two entries in netflow_ports, concurrent template redefinition and data-flowset processing can let add_update_peer_template() reassign the template and free its records vector while another listener dereferences the escaped pointer. An unauthenticated sender that can reach both NetFlow/IPFIX listener ports can trigger a heap-use-after-free and reliably crash FastNetMon. No fixed release is available as of this review. |
| The vulnerability is a Use-After-Free (UAF) in the EVS AIDL HAL, arising from a data race on an unsynchronized `std::weak_ptr` within `EvsEnumerator::openCamera()`. Specifically, concurrent calls from a privileged UID (e.g., `AID_AUTOMOTIVE_EVS`) can cause a torn `weak_ptr` state, leading to a virtual call through a freed object's vtable at `cameraObj->getCameraInfo(&desc)`. This allows for potential arbitrary code execution within the `hal_evs_default` process. |
| Use-after-free in the Layout component. This vulnerability was fixed in Firefox 160 and Thunderbird 160. |
| Use-after-free in the CSS Parsing and Computation component. This vulnerability was fixed in Firefox 160 and Thunderbird 160. |
| Use-after-free in the SVG component. This vulnerability was fixed in Firefox 160 and Thunderbird 160. |
| Sandbox escape due to use-after-free in the DOM: Service Workers component. This vulnerability was fixed in Firefox 160 and Thunderbird 160. |
| Use-after-free in the Layout: Positioned component. This vulnerability was fixed in Firefox 160 and Thunderbird 160. |
| Use-after-free in the DOM: HTML Parser component. This vulnerability was fixed in Firefox 160 and Thunderbird 160. |
| Use-after-free in the DOM: Editor component. This vulnerability was fixed in Firefox 160 and Thunderbird 160. |
| IBM Watson Speech Services Cartridge 4.0.0 through 5.4.0 could allow a remote attacker to execute arbitrary code due to a use-after-free vulnerability. |
| Issue summary: A retransmitted QUIC CRYPTO frame can release packet storage
while the TLS record layer retains a direct pointer into that storage causing
use after free.
Impact summary: A malicious QUIC server can cause a heap-use-after-free read
in the OpenSSL QUIC client. The server can also identify one allocator-adjacent
byte through the client's protected Handshake response.
CWE: CWE-416: Use After Free
Description: During CRYPTO stream processing, a pointer into the first frame's
memory on the stream is lent to the TLS handshake processing. The memory
must remain stable until it is processed and released. However the processing
of retransmitted CRYPTO frames could release the memory if the retransmitted
frame fully overlapped the existing frame. This then causes use-after-free read
when the TLS handshake processing continues.
The use-after-free read can lead to a Denial-of-Service of the client
application or a minor leak of information about the heap memory contents
that might be overwritten with other data, subsequently allocated by
the application, to the peer.
FIPS impact: no
The FIPS module is not affected as the QUIC implementation is outside of
the OpenSSL FIPS module boundary. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: validate readdir offset before accessing dirent
A corrupted directory can trigger the following KASAN report when
ext4_readdir() resumes from an invalid position:
BUG: KASAN: use-after-free in __ext4_check_dir_entry+0x5ef/0x820
Read of size 2 at addr ffff88810a646000 by task repro_linear/509
Call Trace:

</TASK>
KASAN reports use-after-free because the out-of-bounds access lands in an
adjacent freed page. The directory buffer itself is still referenced.
ext4_dir_llseek() invalidates the directory cookie so that ext4_readdir()
rescans directory entries from the start of the block. The rescan checks
only the lower bound of rec_len before advancing. A corrupted rec_len can
therefore place the offset where the block has insufficient space for a
complete directory entry. The rescan itself may dereference that truncated
entry, or the main loop may pass it to __ext4_check_dir_entry(). The latter
reads de->rec_len before validating the range. For example:
block offset 0 4092 4096
|---- de1.rec_len = 4092 -----|----|
de2.inode
| de2.rec_len
^ OOB, reported as UAF
de2 starts at offset 4092 in this 4 KiB block. Its four-byte inode fits in
the block, but its rec_len starts at offset 4096 and crosses the boundary.
The minimum safe length is inode-dependent. Encrypted and casefolded
directory entries need eight additional hash bytes, while a valid metadata
checksum tail is only 12 bytes.
Cache the metadata checksum feature state and derive the minimum directory
entry length from the on-disk format. Use it to bound both the rescan and
the offset passed to the main loop. Report an offset in a truncated block
tail and skip the remainder of the block, while continuing to accept an
offset exactly at the block boundary. |
| In multiple locations, there is a possible memory safety issue due to a use-after-free. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation. |
| Use after free in the MigTD virtio driver for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable data corruption. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (high) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts. |
