In the Linux kernel, the following vulnerability has been resolved:
PCI: plda: Protect root bus removal with rescan lock
Hold the pci_rescan_remove_lock lock while stopping and removing a root bus
to avoid racing with concurrent rescan or hotplug operations triggered via
sysfs. Such races may lead to use-after-free issues or system crashes.
