Overview
Affected versions of this package are vulnerable to External Control of Critical State Data via the pcie_sriov_pf_post_load() function, that unconditionally calls register_vfs() regardless of the VF Enable bit state, creating inconsistent internal state when VFs should not be enabled. An attacker can disrupt service availability by sending a malformed migration data stream.
