CVE-2026-46271

A flaw was found in the Linux kernel's ath12k Wi-Fi driver. When a multi-link connection is active, the firmware incorrectly enables Wake-on-Wireless WoW offloads on both primary and secondary links. This misconfiguration can lead to a firmware crash on WCN7850 devices, resulting in a Denial of...

CVE-2026-46248

A flaw was found in the Linux kernel's ath12k Wi-Fi driver. When an arvif Access Point Virtual Interface is initialized in non-AP STA mode and a Multi-Link Operation MLO connection fails before the arvif is fully created, a stale link mapping can persist. This can lead to a kernel warning WARNON...
