CVE-2025-37861

Full vulnerability record from the local CVENow database.

Description

In the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Synchronous access b/w reset and tm thread for reply queue When the task management thread processes reply queues while the reset thread resets them, the task management thread accesses an invalid queue ID (0xFFFF), set by the reset thread, which points to unallocated memory, causing a crash. Add flag 'io_admin_reset_sync' to synchronize access between the reset, I/O, and admin threads. Before a reset, the reset handler sets this flag to block I/O and admin processing threads. If any thread bypasses the initial check, the reset thread waits up to 10 seconds for processing to finish. If the wait exceeds 10 seconds, the controller is marked as unrecoverable.

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: mpi3mr: Acceso síncrono entre los subprocesos de reinicio y tm para la cola de respuestas. Cuando el subproceso de gestión de tareas procesa las colas de respuestas mientras el subproceso de reinicio las reinicia, este último accede a un ID de cola no válido (0xFFFF), establecido por el subproceso de reinicio, que apunta a memoria no asignada, lo que provoca un fallo. Se ha añadido el indicador «io_admin_reset_sync» para sincronizar el acceso entre los subprocesos de reinicio, E/S y administración. Antes de un reinicio, el controlador de reinicio establece este indicador para bloquear los subprocesos de procesamiento de E/S y administración. Si algún subproceso omite la comprobación inicial, el subproceso de reinicio espera hasta 10 segundos a que finalice el procesamiento. Si la espera supera los 10 segundos, el controlador se marca como irrecuperable."
