  2. Vulnerabilities (CVE)
  3. CVE-2024-38556
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Add a timeout to acquire the command queue semaphore Prevent forced completion handling on an entry that has not yet been assigned an index, causing an out of bounds access on idx = -22. Instead of waiting indefinitely for the sem, blocking flow now waits for index to be allocated or a sem acquisition timeout before beginning the timer for FW completion. Kernel log example: mlx5_core 0000:06:00.0: wait_func_handle_exec_timeout:1128:(pid 185911): cmd[-22]: CREATE_UCTX(0xa04) No done completion

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/mlx5: agrega un tiempo de espera para adquirir el semáforo de la cola de comandos. Evita el manejo de finalización forzada en una entrada a la que aún no se le ha asignado un índice, lo que provoca un acceso fuera de los límites en idx = -22. En lugar de esperar indefinidamente el sem, el flujo de bloqueo ahora espera a que se asigne el índice o a que se agote el tiempo de espera de adquisición del sem antes de iniciar el temporizador para completar el FW. Ejemplo de registro del kernel: mlx5_core 0000:06:00.0: wait_func_handle_exec_timeout:1128:(pid 185911): cmd[-22]: CREATE_UCTX(0xa04) No se completó
