Descriptions

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

wifi: mac80211: fix race condition on enabling fast-xmit

fast-xmit must only be enabled after the sta has been uploaded to the driver,
otherwise it could end up passing the not-yet-uploaded sta via drv_tx calls
to the driver, leading to potential crashes because of uninitialized drv_priv
data.
Add a missing sta->uploaded check and re-check fast xmit after inserting a sta.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: mac80211: corrige la condición de ejecución al habilitar fast-xmit fast-xmit solo debe habilitarse después de que el sta se haya cargado en el controlador; de lo contrario, podría terminar pasando el error sta aún cargada a través de llamadas drv_tx al controlador, lo que genera posibles fallas debido a datos drv_priv no inicializados. Agregue una estación faltante->comprobación cargada y vuelva a verificar la transmisión rápida después de insertar una estación.

A vulnerability was found in the mac80211 driver in the Linux kernel. This issue could lead to potential crashes or memory corruption due to of a situation where the driver attempts to utilize data structures that haven't been fully initialized yet.
