CVE-2026-64362

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

HID: lg-g15: cancel pending work on remove to fix a use-after-free

lg_g15_data is allocated with devm and holds a work item. The report

handlers schedule that work straight from device input.

lg_g15_event() and lg_g15_v2_event() do it on the backlight cycle key,

and lg_g510_leds_event() does it too. The worker dereferences the

lg_g15_data back through container_of.

The driver had no remove callback and never cancelled the work. So if a

report scheduled the work and the keyboard was then unplugged, devres

freed lg_g15_data while the work was still pending or running, and the

worker touched freed memory. This is a use-after-free. It is reachable

as a race on device unplug.

Add a remove callback that cancels the work before devres frees the

state. g15->work is only initialized for the models that schedule it

(G15, G15 v2, G510). The G13 and Z-10 leave it zeroed, so guard the

cancel on g15->work.func to avoid cancellin

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
