CVE-2025-38137

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.
