CVE-2025-21906CVE-2025-21906

linux / linux_kernel

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.
