SUSE CVE-2022-50636

In the Linux kernel, the following vulnerability has been resolved: PCI: Fix pcideviceispresent for VFs by checking PF pcideviceispresent previously didn't work for VFs because it reads the Vendor and Device ID, which are 0xffff for VFs, which looks like they aren't present. Check the PF instead...

A flaw was found in the way the Linux kernel’s PCI subsystem detects the presence of devices for Single Root I/O Virtualization,Virtual Functions VFs. The existing pcideviceispresent implementation incorrectly determines that VFs are absent by reading the Vendor and Device IDs, which return 0xfff...
