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().</p> <p>Potentially this could be reproduced with something like: testj1939 -r vcan0:0x80 &amp; while true; do # send first RTS cansend vcan0 18EC8090#1014000303002301; # send second RTS cansend vcan0 18EC8090#1014000303002301; # send abort cansend vcan0 18EC8090#ff00000000002301; done</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>net: can: j1939: enhanced error handling for tightly received RTS messages in xtp_rx_rts_session_new</p> <p>This patch enhances error handling in scenarios with RTS (Request to Send) messages arriving closely.
