A flaw was found in the Linux kernel. A use-after-free may be triggered in
asus_kbd_backlight_set when plugging/disconnecting in a malicious USB
device, which advertises itself as an Asus device. Similarly to the
previous known CVE-2023-25012, but in asus devices, the work_struct may be
scheduled by the LED controller while the device is disconnecting,
triggering a use-after-free on the struct asus_kbd_leds *led structure. A
malicious USB device may exploit the issue to cause memory corruption with
controlled data.

Notes

Author	Note
sbeattie	requires physical access to plug in/remove a malicious USB device.
