Title
perf/amd/ibs: Avoid calling perf_allow_kernel() from the IBS NMI handler
Summary
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.
Severity
No CVSS data available.
