AI-suggested
A patch is available and has been released by the vendor. Users should update their Linux kernel packages to the fixed versions as listed in the Ubuntu security advisories USN-7699-1 and USN-7699-2. After applying the update, a system reboot is required to complete the remediation. Due to ABI changes, recompilation and reinstallation of third-party kernel modules may be necessary. No additional mitigations are indicated by the vendor advisory.
Description
A null pointer dereference vulnerability was identified and fixed in the Linux kernel's mtk-pmic-keys input driver. The issue occurs when the regs parameter is not set due to hardware configurations where the button node is removed, leading to a potential null pointer dereference. This flaw has been addressed by using a regs struct defined for all supported platforms. The vulnerability is part of a broader set of Linux kernel security fixes affecting multiple subsystems. A patch is available and included in updated Linux kernel packages. Users are advised to update and reboot their systems to apply the fixes.
