"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: can: j1939: enhanced error handling for tightly received RTS messages in xtp_rx_rts_session_new\n\nThis patch enhances error handling in scenarios with RTS (Request to\nSend) messages arriving closely. It replaces the less informative WARN_ON_ONCE\nbacktraces with a new error handling method. This provides clearer error\nmessages and allows for the early termination of problematic sessions.\nPreviously, sessions were only released at the end of j1939_xtp_rx_rts().\n\nPotentially this could be reproduced with something like:\ntestj1939 -r vcan0:0x80 &\nwhile true; do\n\t# send first RTS\n\tcansend vcan0 18EC8090#1014000303002301;\n\t# send second RTS\n\tcansend vcan0 18EC8090#1014000303002301;\n\t# send abort\n\tcansend vcan0 18EC8090#ff00000000002301;\ndone"

An unauthenticated CAN/J1939 peer can trigger it without local code execution on the target, consistent with other packet-triggered j1939 scores.\nAC:L - The attacker reliably triggers the bug by sending tightly spaced duplicate RTS (and abort) frames, as in the documented cansend reproducer; the attacker fully controls packet contents and timing.\nPR:N - J1939/CAN receive processing has no authentication gate; once a legitimate J1939 socket is bound on the victim (normal for J1939 deployments), an unauthenticated bus peer can inject the crafted RTS sequence.\nUI:N - No user action is required beyond the target already running the J1939 stack with a bound socket; the attacker only needs to transmit frames.\nS:U - Impact is confined to kernel J1939 session handling within the same kernel security authority and does not cross VM, IOMMU, or sandbox boundaries.\nC:N - The failure path is a WARN_ON_ONCE plus continued use of a never-activated session that is later freed via timer refs; investigation found no info leak, OOB read, or UAF disclosure primitive.\nI:N - No out-of-bounds write, type confusion, or other integrity/write primitive was identified; the ghost session may confuse transport state but does not yield attacker-controlled memory modification.\nA:H - WARN_ON_ONCE in softirq receive context can panic the kernel (e.g. panic_on_warn), and the bug can be retriggered repeatedly by an adjacent/network peer to deny J1939/CAN service."
