AI-suggested

A fix is available and has been released in multiple Linux kernel versions including 5.15.0-1095.102~20.04.1 and later. Users should upgrade to these fixed kernel versions to remediate the vulnerability. No additional mitigation is required as the issue is resolved by the patch.

Description

CVE-2024-26896 is a vulnerability in the Linux kernel's wfx WiFi driver that causes a memory leak when starting an access point (AP). The issue arises because memory allocated by ieee80211_beacon_get() is not released in the wfx_set_mfp_ap() function. This leak was detected by kmemleak and fixed in several Linux kernel versions. The vulnerability has a medium severity score and does not impact confidentiality or integrity but can cause denial of service due to resource exhaustion.
