CVE-2026-23271

perf: Fix __perf_event_overflow() vs perf_remove_from_context() race

In the Linux kernel, the following vulnerability has been resolved:

perf: Fix __perf_event_overflow() vs perf_remove_from_context() race

Make sure that __perf_event_overflow() runs with IRQs disabled for all
possible callchains. Specifically the software events can end up running
it with only preemption disabled.

This opens up a race vs perf_event_exit_event() and friends that will go
and free various things the overflow path expects to be present, like
the BPF program.
