CVE-2026-74637

CVE-2026-74637 is a use-after-free in the Linux kernel's perf subsystem . When a perf event group sibling is detached during CPU hotplug (DETACH_GROUP), it is removed from the leader's sibling list but its group_leader pointer is left stale. If the leader is later freed, a PERF_IOC_FLAG_GROUP ioc...
