CVE-2022-49498

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Check for null pointer of pointer substream before dereferencing it Pointer substream is being dereferenced on the assignment of pointer card before substream is being null checked with the macro PCMRUNTIMECHECK...

CVE-2022-49498

CVE-2022-49498 affects the Linux kernel, specifically the ALSA PCM path. The issue: a pointer substream could be dereferenced before a null check (PCM_RUNTIME_CHECK), risking a crash/denial of service if triggered locally. The connected advisories (e.g., Astra Linux, SUSE SU-2025 updates) confirm...

CVE-2022-49292

CVE-2022-49292 is tied to the Linux kernel ALSA oss PCM buffer allocation overflow. The vulnerability occurs when snd_pcm_plug_alloc() may allocate an oversized temporary buffer during data conversion if hardware parameters allow larger-than-expected period/buffer sizes, risking an INT_MAX overfl...

CVE-2022-49292

In the Linux kernel, the following vulnerability has been resolved: ALSA: oss: Fix PCM OSS buffer allocation overflow We've got syzbot reports hitting INTMAX overflow at vmalloc allocation that is called from sndpcmplugalloc. Although we apply the restrictions to input parameters, it's based only...

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...
