CVE-2023-1079: Use After Free

First published: Sun Feb 26 2023(Updated: )

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 <a href="https://access.redhat.com/security/cve/CVE-2023-25012">CVE-2023-25012</a>, 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.
