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