Estado: RecibidaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

PCI: iproc: 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.
