CVE-2026-90331: HID: asus: refactor the two workqueues and init sequence
In the Linux kernel, the following vulnerability has been resolved:
HID: asus: refactor the two workqueues and init sequence
Multiple issues have been found within the hid-asus driver: - unchecked size in asusrawevent() - unclean teardown of asusprobe on failure - possible use-after-free in asusprobe - multiple workqueue used for jobs where one was enough - sleeping calls in atomic context - packets of incorrect size being sent to the keyboard controller
Join the two workqueues into one reusing the stopping mechanism of the brightness workqueue, use the joined workqueue to also move the asuswmisendevent() sleeping call away from atomic context and add a size check in asusrawevent().
