Security Advisory Description
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. (CVE-2021-28972)
Impact
There is no impact; F5 products are not affected by this vulnerability.
