CVE-2025-39750
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Correct tid cleanup when tid setup fails Currently, if any error occurs during ath12k_dp_rx_peer_tid_setup(), the tid value is already incremented, even though the corresponding TID is not actually allocated. Proceed to ath12k_dp_rx_peer_tid_delete() starting from unallocated tid, which might leads to freeing unallocated TID and cause potential crash or out-of-bounds access. Hence, fix by correctly decrementing tid before cleanup to match only the successfully allocated TIDs. Also, remove tid-- from failure case of ath12k_dp_rx_peer_frag_setup(), as decrementing the tid before cleanup in loop will take care of this. Compile tested only.

"value": "En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:\n\nwifi: ath12k: Limpieza correcta de tid cuando la configuración de tid falla\n\nActualmente, si ocurre algún error durante ath12k_dp_rx_peer_tid_setup(), el valor de tid ya está incrementado, a pesar de que el TID correspondiente no está realmente asignado. Se procede a ath12k_dp_rx_peer_tid_delete() comenzando desde un tid no asignado, lo que podría llevar a liberar un TID no asignado y causar un posible fallo o acceso fuera de límites.\n\nPor lo tanto, se corrige decrementando correctamente tid antes de la limpieza para que coincida solo con los TIDs asignados con éxito.\n\nAdemás, se elimina tid-- del caso de fallo de ath12k_dp_rx_peer_frag_setup(), ya que decrementar el tid antes de la limpieza en el bucle se encargará de esto.\n\nSolo probado en compilación."
