CVE-2022-49538

CVE-2022-49538 affects the Linux kernel’s ALSA jack path in ASoC. The issue arises when input_dev is unregistered while snd_jack_report is called, potentially causing a NULL pointer dereference. The documented fix is to serialize access to input_dev using a mutex. The connected sources confirm th...

CVE-2022-49291

The CVE-2022-49291 entry describes a Linux kernel flaw in ALSA: pcm where concurrent hw_params and hw_free ioctls could trigger a use-after-free. The fix introduces a dedicated mutex (runtime->buffer_mutex) and applies it to both hw_params and hw_free code paths, with small reordering (mmap_co...

CVE-2022-49286

CVE-2022-49286 is tied to a Linux kernel TPM space fix: tpm2_del_space() was missing proper teardown after series conversion, leading to a tiny race where chip->tpm_mutex could be dereferenced if the space flush occurs after removal. The accepted mitigation is to convert tpm2_del_space() to us...

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...
