CVE-2022-50698
Description
A flaw was found in the Linux kernel's ASoC da7219 audio codec driver. An error handling path in da7219_register_dai_clks() incorrectly attempts to unregister a clock that was never successfully registered. This could lead to incorrect resource cleanup during driver probe failure, potentially causing system instability.
Statement
This is an error handling path bug that only manifests during driver probe failures for the da7219 audio codec. The issue requires specific hardware (Dialog Semiconductor DA7219) and a failure condition during clock registration. Normal operation is unaffected, and the practical exploit scenario is very limited.
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).
