No race or uncontrollable condition is required.\nPR:L - The attacker needs control of an assigned VF but no PF or host administrative privilege or mailbox authentication. Delegated VF access is a low privilege in the originating tenant scope.\nUI:N - The PF processes the VF mailbox command automatically without any victim action.\nS:C - An untrusted VM or workload can control the VF while the malformed request corrupts the host PF kernel, crossing the tenant-to-host security boundary.\nC:H - The 16-bit ID reaches roughly 7.5 KiB beyond the bitmap into adjacent pointers and structures. The resulting corruption can enable host-kernel code execution and arbitrary memory disclosure.\nI:H - Invalid delete and add requests provide selected bit-set and bit-clear operations over adjacent kernel data, enabling pointer corruption and potentially host-kernel code execution.\nA:H - The repeatable out-of-bounds atomic memory operations can corrupt or fault kernel memory, directly causing a host kernel oops, panic, or hang." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
