- Summary
- perf/amd/ibs: Avoid calling perf_allow_kernel() from the IBS NMI handler
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
perf/amd/ibs: Avoid calling perfallowkernel() from the IBS NMI handler
Calling perfallowkernel() 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.
