CVE-2026-46328 Details
Description
In the Linux kernel, the following vulnerability has been resolved: apparmor: fix rlimit for posix cpu timers Posix cpu timers requires an additional step beyond setting the rlimit. Refactor the code so its clear when what code is setting the limit and conditionally update the posix cpu timers when appropriate.
A vulnerability exists in the Linux kernel's AppArmor module regarding the management of resource limits (rlimits) for POSIX CPU timers. The issue arises because POSIX CPU timers require an additional step beyond merely setting the rlimit. The code needs to be refactored to clarify when the limits are being set and to conditionally update the POSIX CPU timers as necessary. This vulnerability affects several versions of the Linux kernel.
Users can update to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for downloading the patched kernel can be found on the official Linux kernel website.
