CVE-2025-37802

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-37802
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix WARNING "do not call blocking ops when !TASK_RUNNING" wait_event_timeout() will set the state of the current task to TASK_UNINTERRUPTIBLE, before doing the condition check. This means that ksmbd_durable_scavenger_alive() will try to acquire the mutex while already in a sleeping state. The scheduler warns us by giving the following warning: do not call blocking ops when !TASK_RUNNING; state=2 set at [<0000000061515a6f>] prepare_to_wait_event+0x9f/0x6c0 WARNING: CPU: 2 PID: 4147 at kernel/sched/core.c:10099 __might_sleep+0x12f/0x160 mutex lock is not needed in ksmbd_durable_scavenger_alive().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ksmbd: corrección de la ADVERTENCIA "no llamar a operaciones de bloqueo cuando !TASK_RUNNING" wait_event_timeout() establecerá el estado de la tarea actual en TASK_UNINTERRUPTIBLE antes de realizar la comprobación de condición. Esto significa que ksmbd_durable_scavenger_alive() intentará adquirir el mutex mientras ya está en estado de suspensión. El programador nos advierte con la siguiente advertencia: no llamar a operaciones de bloqueo cuando !TASK_RUNNING; estado=2 establecido en [&lt;0000000061515a6f&gt;] prepare_to_wait_event+0x9f/0x6c0 ADVERTENCIA: CPU: 2 PID: 4147 en kernel/sched/core.c:10099 __might_sleep+0x12f/0x160 El bloqueo mutex no es necesario en ksmbd_durable_scavenger_alive().
