CVE-2026-53102

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: mt76: Fix memory leak after mt76_connac_mcu_alloc_sta_req()<br /> <br /> mt76_connac_mcu_alloc_sta_req() allocates an skb which is expected to<br /> be freed eventually by mt76_mcu_skb_send_msg(). However, currently if<br /> an intermediate function fails before sending, the allocated skb is<br /> leaked.<br /> <br /> Specifically, mt76_connac_mcu_sta_wed_update() and<br /> mt76_connac_mcu_sta_key_tlv() may fail, leading to an immediate memory<br /> leak in the error path.<br /> <br /> Fix this by explicitly freeing the skb in these error paths.<br /> Commit 7c0f63fe37a5 ("wifi: mt76: mt7996: fix memory leak on<br /> mt7996_mcu_sta_key_tlv error") made a similar change.<br /> <br /> Compile tested only. Issue found using a prototype static analysis tool<br /> and code review.
