CVE-2026-74637

A flaw was found in the Linux kernel's perf subsystem. A local attacker could exploit a use-after-free vulnerability when a perf event group's sibling is detached but remains active, and its pointer to the group leader is not properly updated. This improper handling can lead to a system crash,...

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...
