What to do
AI-suggested
A fix has been implemented in the Linux kernel to address this issue by modifying the mtk_pmic_keys_probe function to use a consistently defined regs struct. Users should update to the fixed kernel version once available. No additional mitigation steps are specified.
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 device tree does not define a button node, causing the code to dereference a null pointer. The fix involves using a regs struct that is always defined for supported platforms to avoid this dereference.
