CVE-2025-37886

  3. CVE-2025-37886
In the Linux kernel, the following vulnerability has been resolved: pds_core: make wait_context part of q_info Make the wait_context a full part of the q_info struct rather than a stack variable that goes away after pdsc_adminq_post() is done so that the context is still available after the wait loop has given up. There was a case where a slow development firmware caused the adminq request to time out, but then later the FW finally finished the request and sent the interrupt. The handler tried to complete_all() the completion context that had been created on the stack in pdsc_adminq_post() but no longer existed. This caused bad pointer usage, kernel crashes, and much wailing and gnashing of teeth.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pds_core: hacer que wait_context forme parte de q_info Hacer que wait_context sea una parte completa de la estructura q_info en lugar de una variable de pila que desaparezca después de que pdsc_adminq_post() se complete para que el contexto siga disponible después de que el bucle de espera se haya dado por vencido. Hubo un caso en el que un firmware de desarrollo lento provocó que la solicitud adminq expirara, pero luego el FW finalmente terminó la solicitud y envió la interrupción. El controlador intentó completar_todo() el contexto de finalización que se había creado en la pila en pdsc_adminq_post() pero ya no existía. Esto causó un mal uso del puntero, fallos del kernel y muchos lamentos y crujir de dientes.
