Title
wifi: mt76: mt7921: fix kernel panic due to null pointer dereference
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: fix kernel panic due to null pointer dereference Address a kernel panic caused by a null pointer dereference in the `mt792x_rx_get_wcid` function. The issue arises because the `deflink` structure is not properly initialized with the `sta` context. This patch ensures that the `deflink` structure is correctly linked to the `sta` context, preventing the null pointer dereference.
