CVE-2026-99187

The Linux kernel contains a vulnerability in the perf subsystem where __perf_pmu_remove() prematurely ends its walk of group leaders because perf_remove_from_context() removes the leader from the rbtree, causing rb_next() to return NULL. This results in some groups remaining in the source context...
