CVE-2023-53866
Description
A locking issue was found in the ASoC (ALSA SoC) compressed audio subsystem in the Linux kernel. When DPCM (Dynamic PCM) compressed streams are started, several functions access resources without properly holding the card->pcm_mutex lock. This triggers lock assertion warnings and can cause kernel panics if panic_on_warn is enabled.
Statement
This is a locking issue in the ASoC compressed audio subsystem that causes warnings and potential panics. The impact is primarily on systems using compressed audio with DPCM routing and panic_on_warn enabled.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
