Descriptions

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath12k: fix possible out-of-bound read in ath12k_htt_pull_ppdu_stats()

len is extracted from HTT message and could be an unexpected value in
case errors happen, so add validation before using to avoid possible
out-of-bound read in the following message iteration and parsing.

The same issue also applies to ppdu_info->ppdu_stats.common.num_users,
so validate it before using too.

These are found during code review.

Compile test only.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: wifi: ath12k: corrige una posible lectura fuera de los límites en ath12k_htt_pull_ppdu_stats(). len se extrae del mensaje HTT y podría ser un valor inesperado en caso de que ocurran errores, así que agregue validación antes de usarlo para evitar una posible lectura fuera de los límites en la siguiente iteración y análisis del mensaje. El mismo problema también se aplica a ppdu_info->ppdu_stats.common.num_users, así que valídelo antes de usarlo también. Estos se encuentran durante la revisión del código. Compilar prueba únicamente.
