In the Linux kernel, the following vulnerability has been resolved:
perf/x86: Fix potential bad containerof in intelpmuhwconfig
Auto counter reload may have a group of events with software events present within it. The software event PMU isn't the x86hybridpmu and a containerof operation in intelpmusetacrcausedconstr (via the hybrid helper) could cause out of bound memory reads. Avoid this by guarding the call to intelpmusetacrcausedconstr with an isx86_event check.
