  3. CVE-2023-52887
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

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: can: j1939: manejo de errores mejorado para mensajes RTS recibidos estrechamente en xtp_rx_rts_session_new Este parche mejora el manejo de errores en escenarios con mensajes RTS (Solicitud de envío) que llegan cerca. Reemplaza los rastreos WARN_ON_ONCE menos informativos con un nuevo método de manejo de errores. Esto proporciona mensajes de error más claros y permite la finalización anticipada de sesiones problemáticas. Anteriormente, las sesiones sólo se publicaban al final de j1939_xtp_rx_rts(). Potencialmente, esto podría reproducirse con algo como: testj1939 -r vcan0:0x80 & while true; hacer # enviar primero RTS cansend vcan0 18EC8090#1014000303002301; # enviar segundo RTS cansend vcan0 18EC8090#1014000303002301; # enviar cancelar cansend vcan0 18EC8090#ff00000000002301; hecho
