CVE-2024-40965

Description

A vulnerability was found in the lpi2c driver in the Linux kernel's i2c subsystem, where the clk_get_rate function is called during data transfers, which can lead to a deadlock situation when an audio codec attempts to access the i2c bus while holding the clock mutex, resulting in a denial of service.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

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).
