Descriptions

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

wifi: iwlwifi: mvm: guard against invalid STA ID on removal

Guard against invalid station IDs in iwl_mvm_mld_rm_sta_id as that would
result in out-of-bounds array accesses. This prevents issues should the
driver get into a bad state during error handling.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: wifi: iwlwifi: mvm: proteger contra ID de STA no válido al eliminarlo Proteger contra ID de estación no válidos en iwl_mvm_mld_rm_sta_id ya que eso daría como resultado accesos a la matriz fuera de los límites. Esto evita problemas en caso de que el controlador entre en mal estado durante el manejo de errores.

An out-of-bounds memory access flaw was found in the Linux kernel’s Wireless WiFi Link Next-Gen AGN driver in how a user removes it. This flaw allows a local user to crash or potentially escalate their privileges on the system.
