Summary
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.

En caso de retraso en la interrupci\u00f3n por cualquier motivo, slim_do_transfer() devuelve un error de tiempo de espera, pero el ID de transacci\u00f3n (TID) no se libera. Esto provoca un acceso no v\u00e1lido a memoria dentro de qcom_slim_ngd_rx_msgq_cb() debido a un TID no v\u00e1lido.
