CVE-2024-56560

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.12.0

Description The issue is related to a too strict alignment check in the create cache() function, which can cause a kernel panic on certain systems, such as m68k, where the minimum alignment of unsigned long is 2 bytes. The error occurs when trying to create a slab cache, resulting in a failed allocation. The problem arises from the assumption that an arbitrary freeptr t (basically an unsigned long) is always aligned to 4 or 8 bytes, which is not safe. The fix involves relaxing the check to the actual minimum alignment of freeptr t.

Recommendations To resolve the issue, update to a version of the Linux kernel that includes the fix for the too strict alignment check in create cache(). At the moment, there is no information about a newer version that contains a fix for this vulnerability.
