CVE-2026-74637

CVE-2026-74637 is a use-after-free vulnerability in the Linux kernel's perf/core subsystem. When a perf event sibling is detached via DETACH_GROUP (e.g., during CPU hot-unplug), its group_leader pointer is left pointing at the old leader instead of being reset. If the leader is subsequently freed...

CVE-2026-72237

A flaw was found in the Linux kernel. A local user can exploit a vulnerability in the perf subsystem on AMD processors utilizing the Branch Sampling BRS feature. This flaw occurs because the software filtering mechanism for branch records only validates the branch-to address, leaving the...
