Detailsinfo

A vulnerability has been found in Linux Kernel up to 6.1.80/6.6.20/6.7.8 and classified as problematic. This vulnerability affects an unknown functionality of the component neonbs. The manipulation with an unknown input leads to a out-of-bounds vulnerability. The CWE definition for the vulnerability is CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. As an impact it is known to affect confidentiality. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: crypto: arm64/neonbs - fix out-of-bounds access on short input The bit-sliced implementation of AES-CTR operates on blocks of 128 bytes, and will fall back to the plain NEON version for tail blocks or inputs that are shorter than 128 bytes to begin with. It will call straight into the plain NEON asm helper, which performs all memory accesses in granules of 16 bytes (the size of a NEON register). For this reason, the associated plain NEON glue code will copy inputs shorter than 16 bytes into a temporary buffer, given that this is a rare occurrence and it is not worth the effort to work around this in the asm code. The fallback from the bit-sliced NEON version fails to take this into account, potentially resulting in out-of-bounds accesses. So clone the same workaround, and use a temp buffer for short in/outputs.

The advisory is available at git.kernel.org. This vulnerability was named CVE-2024-26789 since 02/19/2024. The technical details are unknown and an exploit is not available.

Upgrading to version 6.1.81, 6.6.21, 6.7.9 or 6.8 eliminates this vulnerability. Applying the patch 034e2d70b5c7/1291d278b557/9e8ecd4908b5/1c0cf6d19690 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.

The vulnerability is also documented in the vulnerability database at CERT Bund (WID-SEC-2024-0773). If you want to get best quality of vulnerability data, you may have to visit VulDB.
