CVE-2025-21914

  2. Vulnerabilities (CVE)
  3. CVE-2025-21914
In the Linux kernel, the following vulnerability has been resolved: slimbus: messaging: Free transaction ID in delayed interrupt scenario In case of interrupt delay for any reason, slim_do_transfer() returns timeout error but the transaction ID (TID) is not freed. This results into invalid memory access inside qcom_slim_ngd_rx_msgq_cb() due to invalid TID. Fix the issue by freeing the TID in slim_do_transfer() before returning timeout error to avoid invalid memory access.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: slimbus: mensajería: ID de transacción libre en un escenario de interrupción retrasada. En caso de retraso en la interrupción por cualquier motivo, slim_do_transfer() devuelve un error de tiempo de espera, pero el ID de transacción (TID) no se libera. Esto provoca un acceso no válido a memoria dentro de qcom_slim_ngd_rx_msgq_cb() debido a un TID no válido. Para solucionar el problema, libere el TID en slim_do_transfer() antes de devolver el error de tiempo de espera para evitar accesos no válidos a memoria.
