CVE-2026-112393 2 Python, Python-pillow 2 Pillow, Pillow 2026-10-26 9.8 Critical
Pillow is a Python imaging library. From 2.0.0 until 13.0.0, Pillow has a heap buffer overflow and stale-heap disclosure in _tiffWriteProc when saving compressed TIFF data through libtiff to a target without a usable fileno(), such as BytesIO. The callback sizes its allocation from the prior buffer size instead of the current write position, allowing an attacker-controlled out-of-line TIFF tag or retained ICC profile to be copied beyond the allocation after libtiff seeks forward. This overflow can crash the process and may allow code execution. Independently, unwritten alignment gaps in compressed TIFF output larger than 64 KiB can disclose stale heap bytes without a crafted tag. File paths and targets with real file descriptors are unaffected. This issue is fixed in version 13.0.0.

CVE-2026-116262 1 Libimobiledevice 1 Libimobiledevice 2026-10-26 5.4 Medium
A vulnerability was detected in libimobiledevice up to 1.4.0. The affected element is the function webinspector_receive_with_timeout of the file src/webinspector.c of the component Web Inspector. The manipulation results in heap-based buffer overflow. It is possible to launch the attack remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-99098 1 Linux 2 Linux, Linux Kernel 2026-10-26 4.4 Medium
In the Linux kernel, the following vulnerability has been resolved: dm-integrity: fix buffer overflow in inline mode with large tag size In inline mode, dm_integrity_check and dm_integrity_inline_recheck compute the checksum of each block into an on-stack buffer of HASH_MAX_DIGESTSIZE bytes. integrity_sector_checksum pads its result with zeroes up to the tag size, so if the tag size is larger than HASH_MAX_DIGESTSIZE, the padding runs past the end of the buffer. With CONFIG_STACKPROTECTOR the kernel panics in dm_integrity_check on the first read. Enlarge both buffers to hold MAX_TAG_SIZE bytes, as commit b93b6643e9b5 ("dm integrity: fix a crash with unusually large tag size") did for integrity_metadata. Note that this is not a security bug because the buffer overflow can only be triggered by root.
