In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux kernel through 5.11.8,
the RPA PCI Hotplug driver has a user-tolerable buffer overflow when
writing a new device name to the driver from userspace, allowing userspace
to write data to the kernel stack frame directly. This occurs because
add_slot_store and remove_slot_store mishandle drc_name ‘\0’ termination,
aka CID-cc7a0bb058b8.
