Return To CVE Listing for 2021

NameCVE-2021-28972
StatusCandidate
DescriptionIn 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 '' termination, aka CID-cc7a0bb058b8.
