Description

This security bulletin contains information about 1 vulnerability.


1) Use-after-free (CVE-ID: CVE-2026-64362)

CWE-ID: CWE-416 - Use After Free

CVSSv4: 5.1 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows an attacker with physical access to cause a denial of service.

The vulnerability exists due to use-after-free in the hid-lg-g15 driver work handling logic when a pending work item is triggered and the device is unplugged. An attacker with physical access can trigger a backlight cycle key event and disconnect the keyboard to cause a denial of service.

The issue is reachable as a race condition on device unplug for G15, G15 v2, and G510 models that initialize the work item.
