AI-suggested
A patch is available and should be applied to affected Linux kernel versions. The fix prevents multiple allocations of rx_stats by checking if it is already allocated before allocating again. Users should update to Linux kernel versions 6.14.0-1007.7 or later, 6.14.0-1014.14 or later, or other patched versions as per vendor advisories. No additional mitigation is required beyond applying the official fix.
Description
A memory leak vulnerability in the Linux kernel's ath12k WiFi driver was fixed. The issue occurs due to redundant allocations of rx_stats when the same station is added multiple times, causing memory leaks. This affects certain Linux kernel versions prior to 6.14.0-1007.7 and 6.14.0-1014.14, as well as specific older versions enumerated. The vulnerability has a medium severity with a CVSS score of 5.5 and impacts availability but not confidentiality or integrity. A patch is available and has been incorporated in updated Linux kernel releases.
