| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.12.0-rc5mm-unstable-arm64+
Description
The issue arises from a commit that reduced the minimum alignment for kmalloc() to 8 on arm64, but with KASAN HW TAGS enabled, the alignment becomes 16. This causes kmalloc caches[][8] to be aliased to kmalloc caches[][16], resulting in kmem buckets create() attempting to create a kmem cache for size 16 twice, triggering warnings on boot. The warnings are related to the creation of kmem cache for names 'memdup user-16' and 'msg msg-16' already existing.
Recommendations
To resolve the issue for Linux kernel versions prior to 6.12.0-rc5mm-unstable-arm64+, update to a version that includes the fix for the duplicate kmem cache creation warning.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
