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-2022-49272

CVE-2022-49272 affects the Linux kernel in ALSA: pcm code. The root cause is a potential AB/BA deadlock between PCM runtime→buffer_mutex and mm→mmap_lock triggered by concurrent access via ALSA and OSS during read/write and mmap/path IOCTLs. The fix replaces the buffer_mutex protection in read/wr...
