Summary
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
