CVE-2025-38292
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix invalid access to memory In ath12k_dp_rx_msdu_coalesce(), rxcb is fetched from skb and boolean is_continuation is part of rxcb. Currently, after freeing the skb, the rxcb->is_continuation accessed again which is wrong since the memory is already freed. This might lead use-after-free error. Hence, fix by locally defining bool is_continuation from rxcb, so that after freeing skb, is_continuation can be used. Compile tested only.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: ath12k: se corrige el acceso no válido a la memoria. En ath12k_dp_rx_msdu_coalesce(), rxcb se obtiene de skb y el booleano is_continuation forma parte de rxcb. Actualmente, tras liberar skb, se accede de nuevo a rxcb->is_continuation, lo cual es incorrecto, ya que la memoria ya está liberada. Esto podría provocar un error de uso tras liberación. Por lo tanto, se debe corregir definiendo localmente el booleano is_continuation desde rxcb, de modo que, tras liberar skb, se pueda usar is_continuation. Solo se ha probado la compilación."
