Summary

A use-after-free vulnerability was found in the HID driver for Logitech G keyboards (lg-g15). The driver did not cancel pending work before freeing memory, allowing access to freed memory when the device is unplugged.

Risk Assessment

An attacker could exploit this vulnerability for remote code execution or privilege escalation by unplugging the keyboard at the right moment.

Recommendation

Apply the Linux kernel patch that adds a remove callback to cancel work before freeing memory.

Original NVD description (English source)

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 cancelling a work that was never set up. The g15 NULL test mirrors the one already in lg_g15_raw_event().
