AI-suggested
An official patch is available and should be applied by updating to a fixed linux-aws kernel version equal to or newer than 6.17.0-1012.12~24.04.1, 6.17.0-1013.13~24.04.1, 6.17.0-1018.18, 6.17.0-1020.20, or 6.17.0-22.22~24.04.1 as appropriate. After updating, a system reboot is required to apply the fix. No additional mitigation is necessary as the patch properly cancels the delayed work to prevent use-after-free.
Description
A use-after-free vulnerability in the Linux kernel's ALPS touchpad driver (dev3_register_work) was fixed. The issue arises from a race condition during device detachment where delayed work may execute after the associated data structure has been freed. This could lead to memory corruption and potentially allow an attacker with local privileges to compromise system integrity and confidentiality. The vulnerability affects specific linux-aws kernel versions prior to 6.17.0-1012.12~24.04.1, 6.17.0-1013.13~24.04.1, 6.17.0-1018.18, 6.17.0-1020.20, and 6.17.0-22.22~24.04.1. A patch is available that properly cancels the delayed work to prevent use-after-free conditions.
