"value": "AV:N - The vulnerable parser processes Ceph messenger v2 AUTH_DONE frames received over TCP from a remote Ceph monitor/OSD/MDS peer. A malicious or compromised network peer can supply the crafted frame during the connection/authentication handshake.\nAC:L - The attacker controls the frame tag, control-segment length, payload_len, and payload contents needed to reach the unchecked callout. No race or hard-to-influence system state is required.\nPR:N - The bug is reached before the peer has been authenticated by the client-side msgr2 handshake. The remote attacker does not need privileges on the victim system.\nUI:N - In a reasonable Ceph deployment, clients connect or reconnect to monitors, OSDs, and MDS daemons automatically as part of mounted filesystem or block-device operation. A malicious reachable peer can trigger the malformed AUTH_DONE response without further victim interaction.\nS:U - The impact is within the kernel/libceph client security authority on the same host. This does not cross a VM, IOMMU, or other separate security scope boundary.\nC:H - The missing bounds check lets a peer-controlled payload_len make auth callbacks treat memory beyond the received control buffer as valid input. This is an unbounded kernel out-of-bounds read, so confidentiality impact is High.\nI:H - Although described as an out-of-bounds read, the auth_x callbacks can decrypt and clear claimed reply data in place based on attacker-controlled lengths. With the required conservative scoring, this can plausibly become kernel memory corruption and is scored as High integrity impact.\nA:H - Reading or cryptographically processing beyond the allocated control buffer can fault, corrupt memory, or otherwise crash the kernel. The malformed handshake frame can be sent repeatedly by the malicious peer."
