CVE-2026-46328
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.11%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
