In the Linux kernel, the following vulnerability has been resolved: HID: wacom: fix crash in wacomaesbatteryhandler() Commit fd2a9b29dc9c ("HID: wacom: Remove AES powersupply after extended inactivity") introduced wacomaesbatteryhandler() which is scheduled as a delayed work (aesbatterywork). In wacomremove(), aesbatterywork is not canceled. Consequently, if the device is removed while aesbatterywork is still pending, then hard crashes or "Oops: general protection fault..." are experienced when wacomaesbatteryhandler() is finally called. E.g., this happens with built-in USB devices after resume from hibernate when aesbatterywork was still pending at the time of hibernation. So, take care to cancel aesbatterywork in wacomremove().
