CVE-2023-1079: Use After Free

Published Feb 26, 2023
·
Updated

A flaw was found in the Linux kernel. A use-after-free may be triggered in asuskbdbacklightset 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 workstruct may be scheduled by the LED controller while the device is disconnecting, triggering a use-after-free on the struct asuskbdleds led structure. A malicious USB device may exploit the issue to cause memory corruption with controlled data.

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=4ab3a086d10eeec1424f2e8a968827a6336203df

Other sources

Linux Kernel is vulnerable to a denial of service, caused by a use-after-free flaw flaw in the asuskbdbacklightset function. By using a specially-crafted USB device, a physical attacker could exploit this vulnerability to cause a denial of service condition.
