CVE-2025-21906 Information

Description

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.
