What is known
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix node corruption in ar->arvifs list In current WLAN recovery code flow, ath12k_core_halt() only reinitializes the "arvifs" list head. This will cause the list node immediately following the list head to become an invalid list node. Because the prev of that node still points to the list head "arvifs", but the next of the list head "arvifs" no longer points to that list node. When a WLAN recovery occurs during the execution of a vif removal, and it happens before the spin_lock_bh(&ar->data_lock) in ath12k_mac_vdev_delete(), list_del() will detect the previously mentioned situation, thereby triggering a kernel panic. The fix is to remove and reinitialize all vif list nodes from the list head "arvifs" during WLAN halt. The reinitialization is to make the list nodes valid, ensuring that the list_del() in ath12k_mac_vdev_delete() can execute normally.

Business impact
Successful exploitation of CVE-2025-38290, a high vulnerability (CVSS 8.8) affecting linux kernel, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
Recommended administrator action
Confirm whether linux kernel is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
