Consequently, if\nthe device is removed while aes_battery_work is still pending, then hard\ncrashes or \"Oops: general protection fault...\" are experienced when\nwacom_aes_battery_handler() is finally called. E.g., this happens with\nbuilt-in USB devices after resume from hibernate when aes_battery_work\nwas still pending at the time of hibernation.\n\nSo, take care to cancel aes_battery_work in wacom_remove().\n\n## Affected\n\n- `linux_kernel >= 6.8, < 6.12.36`\n- `linux_kernel >= 6.13, < 6.15.5`\n- `linux_kernel = 6.16`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.15.5`","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
