CVE-2024-27000
Description
A flaw was found in the mxs-auart module in the Linux kernel. A race condition can occur when changing the cts state due to a missing lock, potentially impacting system stability and possibly resulting in a denial of service.
Statement
The mxs-auart module is not built in the kernel shipped in Red Hat Enterprise Linux 8 and 9, so it is not affected by this vulnerability.
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).
The following CVSS metrics and score provided are preliminary and subject to review.
