This Moderate impact double free vulnerability in the Linux kernel's exFAT filesystem driver affects Red Hat Enterprise Linux 9 and 10. A local attacker with a special group privileges could exploit this flaw, leading to a denial of service, system instability, or crashes.

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).
