"value": "AV:N - rxrpc is a UDP-based network protocol; the bug is in server-side processing of an RxGK RESPONSE packet received from a remote peer, fully reachable over the network.\nAC:H - The vulnerable fall-through is reachable only when the crypto decrypt path returns -ENOMEM (a kernel allocation failure); for all other errors the code correctly aborts, and an attacker cannot reliably force this allocation to fail.\nPR:N - This runs during the RxGK security challenge/response handshake, before the peer is authenticated, so no privileges or credentials are required.\nUI:N - The server processes incoming RESPONSE packets automatically; no victim interaction is needed.\nS:U - Impact is confined to the kernel's own security authority; no VM/IOMMU/sandbox boundary is crossed.\nC:H - Skipping decryption causes the server to accept un-authenticated, attacker-supplied ticket data, letting the attacker control K0/identity/level and impersonate a principal, exposing data served over the authenticated session.\nI:H - The attacker-chosen token sets the connection's session key, security level, and identity without possessing the server key, an authentication bypass that lets the attacker establish a session with forged integrity-relevant parameters.\nA:H - Operating on un-decrypted cryptographic state corrupts the handshake and tears down the connection, and under sustained memory pressure an unauthenticated peer can repeatedly disrupt the RxGK service."
