CVE-2025-21906

  2. Vulnerabilities (CVE)
  3. CVE-2025-21906
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: clean up ROC on failure If the firmware fails to start the session protection, then we do call iwl_mvm_roc_finished() here, but that won't do anything at all because IWL_MVM_STATUS_ROC_P2P_RUNNING was never set. Set IWL_MVM_STATUS_ROC_P2P_RUNNING in the failure/stop path. If it started successfully before, it's already set, so that doesn't matter, and if it didn't start it needs to be set to clean up. Not doing so will lead to a WARN_ON() later on a fresh remain- on-channel, since the link is already active when activated as it was never deactivated.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: iwlwifi: mvm: clean up ROC on fault () Si el firmware no inicia la protección de sesión, entonces llamamos a iwl_mvm_roc_finished() aquí, pero eso no hará nada en absoluto porque IWL_MVM_STATUS_ROC_P2P_RUNNING nunca se configuró. Establezca IWL_MVM_STATUS_ROC_P2P_RUNNING en la ruta de error/detención. Si se inició correctamente antes, ya está configurado, por lo que no importa, y si no se inició, debe configurarse para limpiar. No hacerlo conducirá a un WARN_ON() más tarde en un nuevo canal restante, ya que el enlace ya está activo cuando se activó, ya que nunca se desactivó.
