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

net/liquidio: drop cached VF pci_dev LUT

The PF SR-IOV enable path caches VF pci_dev pointers in

dpiring_to_vfpcidev_lut[] by iterating with pci_get_device(). Those

entries do not own a reference, because the iterator drops the previous

device reference on each step. The cached pointer is then dereferenced

later when handling OCTEON_VF_FLR_REQUEST.

Replace the cached VF mapping with runtime lookup on the mailbox DPI

ring: derive the VF index from q_no, resolve the VF via exported PCI

IOV helpers, validate it with the PF pointer and VF ID, then issue

pcie_flr() and drop the reference with pci_dev_put(). Remove the

unused VF lookup table initialization and cleanup. (NVD)
