In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: Fix memory leak after mt76_connac_mcu_alloc_sta_req() mt76_connac_mcu_alloc_sta_req() allocates an skb which is expected to be freed eventually by mt76_mcu_skb_send_msg(). However, currently if an intermediate function fails before sending, the allocated skb is leaked. Specifically, mt76_connac_mcu_sta_wed_update() and mt76_connac_mcu_sta_key_tlv() may fail, leading to an immediate memory leak in the error path. Fix this by explicitly freeing the skb in these error paths. Commit 7c0f63fe37a5 ("wifi: mt76: mt7996: fix memory leak on mt7996_mcu_sta_key_tlv error") made a similar change. Compile tested only. Issue found using a prototype static analysis tool and code review.
Conclusion & alert: CVE-2026-53102 is rated Low Risk (5.1/100): low exploitation likelihood (EPSS 0.16%). Mandatory action: Low composite risk—no urgent action required; patch on your normal maintenance cycle and revisit priority if CVSS or EPSS increases.
