Description
A flaw was found in the Linux kernel's MT7915 wireless driver. The driver fails to properly disable receive network polling before freeing device resources during hardware teardown or module unloading. This flaw may allow a local privileged user to induce kernel warnings and cause system instability, resulting in a denial of service (DoS).
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.
