kernel: vfio/pci: clear vdev->msi_perm after freeing it on init failure

A flaw was found in the Linux kernel's vfio/pci component. During device initialization, a memory pointer is not properly cleared after being freed, leading to a use-after-free and double-free vulnerability. A local attacker could exploit this flaw to cause a system crash, resulting in a denial o...
