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...
