CVE-2026-53114 Details
Description
In the Linux kernel, the following vulnerability has been resolved: perf/amd/ibs: Avoid calling perf_allow_kernel() from the IBS NMI handler Calling perf_allow_kernel() from the NMI context is unsafe and could be fatal. Capture the permission at event-initialization time by storing it in event->hw.flags, and have the NMI handler rely on that cached flag instead of making the call directly.
A vulnerability has been addressed in the Linux kernel's handling of unprivileged events for AMD Instruction-Based Sampling (IBS) performance monitoring. This issue arises from calling 'perf_allow_kernel()' within the Non-Maskable Interrupt (NMI) context, which is unsafe and potentially fatal. The vulnerability affects the Linux kernel stable tree.
The vulnerability has been fixed in the Linux kernel stable tree. Users should upgrade to the latest version.
