net: can: j1939: enhanced error handling for tightly received RTS messages in xtp_rx_rts_session_new
Noroxi assessment
Priority: Monitor (action score 22/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.67% (FIRST EPSS); higher than 51% of all records.
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Linux Linux 0bc0a7416ea73f79f915c9a05ac0858dff65cfed, 1762ca80c2b72dd1b5821c5e347713ae696276ea, 177e33b655d35d72866b50aec84307119dc5f3d4.
- Severity is disputed: the assigning authority (CNA) scores it 7.5, NVD 5.5.
Low priority for now. Upgrade to Linux Linux 0bc0a7416ea73f79f915c9a05ac0858dff65cfed, 1762ca80c2b72dd1b5821c5e347713ae696276ea, 177e33b655d35d72866b50aec84307119dc5f3d4 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: net: can: j1939: enhanced error handling for tightly received RTS messages in xtp_rx_rts_session_new This patch enhances error handling in scenarios with RTS (Request to Send) messages arriving closely. It replaces the less informative WARN_ON_ONCE backtraces with a new error handling method. This provides clearer error messages and allows for the early termination of problematic sessions. Previously, sessions were only released at the end of j1939_xtp_rx_rts(). Potentially this could be reproduced with something like: testj1939 -r vcan0:0x80 & while true; do # send first RTS cansend vcan0 18EC8090#1014000303002301; # send second RTS cansend vcan0 18EC8090#1014000303002301; # send abort cansend vcan0 18EC8090#ff00000000002301; done
