CVE-2024-35989

Host crash via invalid perf context migration

Published May 20, 2024 · Updated May 11, 2026

Denial of service in affected Linux kernel releases from 5.13 through 6.9-rc5 allows local users to crash hosts during IDXD removal. The perf_event_cpu_offline callback passes an invalid target to perf_pmu_migrate_context when no other CPU is online, causing a kernel-mode page fault and oops. Triggering the flaw requires an IDXD-equipped host with only one CPU online and permission to remove the driver; the documented consequence is a host crash.
