Description
In the Linux kernel, the following vulnerability has been resolved:
PCI/pwrctrl: Cancel outstanding rescan work when unregistering
It's possible to trigger use-after-free here by:
(a) forcing rescan_work_func() to take a long time and
(b) utilizing a pwrctrl driver that may be unloaded for some reason
Cancel outstanding work to ensure it is finished before we allow our data
structures to be cleaned up.
