Vulnerability from github – Published: 2026-01-05 12:30 – Updated: 2026-01-11 18:30

Details

In the Linux kernel, the following vulnerability has been resolved:

mt76: mt7615: Fix memory leak in mt7615_mcu_wtbl_sta_add()

In mt7615_mcu_wtbl_sta_add(), an skb sskb is allocated. If the subsequent call to mt76_connac_mcu_alloc_wtbl_req() fails, the function returns an error without freeing sskb, leading to a memory leak.

Fix this by calling dev_kfree_skb() on sskb in the error handling path to ensure it is properly released.
