CVE-2026-74753

This use-after-free vulnerability in the Linux kernel's perf subsystem occurs because perf_event_open() accepts events in the EXIT state as group leaders, rejecting only REVOKED and DEAD events. After perf_event_remove_on_exec() detaches group relationships, a new sibling can be linked to the det...

In the Linux kernel, the following vulnerability has been resolved: perf/core: Fix perfoutputbegin parameter is incorrectly invoked in perfeventbpfoutput syzkaller reportes a KASAN issue with stack-out-of-bounds. The call trace is as follows: dumpstack+0x9c/0xd3...

CVE-2025-21895

In the Linux kernel, the following vulnerability has been resolved: perf/core: Order the PMU list to fix warning about unordered pmuctxlist Syskaller triggers a warning due to prevepc-pmu != nextepc-pmu in perfeventswaptaskctxdata. vmcore shows that two lists have the same perfeventpmucontext, bu...

CVE-2022-49607

CVE-2022-49607 concerns a data race in the Linux kernel between perf_event_set_output() and perf_mmap_close() in the perf/core subsystem. The root cause is a race where perf_mmap_close() holds e2->mmap_mutex while perf_event_set_output() holds e1->mmap_mutex, allowing no serialization and p...

CVE-2015-8955

CVE-2015-8955 affects the Linux kernel on arm64 (arch/arm64/kernel/perf_event.c) prior to 4.1. The issue arises from events across multiple HW PMUs being mishandled, allowing local users to gain privileges or trigger a denial of service via an invalid pointer dereference. Impact is limited to loc...

CVE-2013-4254

The CVE-2013-4254 issue affects the Linux kernel on ARM where the validate_event function in arch/arm/kernel/perf_event.c before 3.10.8 can be triggered by adding a hardware event to an event group led by a software event, allowing local privilege escalation or causing a NULL pointer dereference ...
