CVE-2026-89465CVE-2026-89465
Description
In the Linux kernel, the following vulnerability has been resolved:
power: supply: rt9455: quiesce delayed work before teardown
The threaded IRQ handler can queue pwr_rdy_work,
max_charging_time_work and batt_presence_work. pwr_rdy_work and
batt_presence_work can also queue max_charging_time_work, while
batt_presence_work can requeue itself.
rt9455_remove() cancels max_charging_time_work before
batt_presence_work. The latter can therefore queue
max_charging_time_work after it has already been cancelled:
rt9455_remove() workqueue
cancel pwr_rdy_work
cancel max_charging_time_work
batt_presence_work queues
max_charging_time_work
cancel batt_presence_work
return
devres frees rt9455_info
max_charging_time_work dereferences
rt9455_info
The IRQ also remains registered until devres cleanup and
