CVE-2026-31782 POC (Proof-of-Concept)

In the Linux kernel, the following vulnerability has been resolved:
perf/x86: Fix potential bad container_of in intel_pmu_hw_config
Auto counter reload may have a group of events with software events
present within it. The software event PMU isn't the x86_hybrid_pmu and
a container_of operation in intel_pmu_set_acr_caused_constr (via the
hybrid helper) could cause out of bound memory reads. Avoid this by
guarding the call to intel_pmu_set_acr_caused_constr with an
is_x86_event check.
