  3. CVE-2024-50062
In the Linux kernel, the following vulnerability has been resolved: RDMA/rtrs-srv: Avoid null pointer deref during path establishment For RTRS path establishment, RTRS client initiates and completes con_num of connections. After establishing all its connections, the information is exchanged between the client and server through the info_req message. During this exchange, it is essential that all connections have been established, and the state of the RTRS srv path is CONNECTED. So add these sanity checks, to make sure we detect and abort process in error scenarios to avoid null pointer deref.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: RDMA/rtrs-srv: Evitar la desreferencia de puntero nulo durante el establecimiento de la ruta Para el establecimiento de la ruta RTRS, el cliente RTRS inicia y completa con_num de conexiones. Después de establecer todas sus conexiones, la información se intercambia entre el cliente y el servidor a través del mensaje info_req. Durante este intercambio, es esencial que se hayan establecido todas las conexiones y que el estado de la ruta RTRS srv sea CONECTADO. Por lo tanto, agregue estas comprobaciones de cordura para asegurarnos de detectar y abortar el proceso en escenarios de error para evitar la desreferencia de puntero nulo.
