| Sažetak |
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.
BUG: kernel NULL pointer dereference, address: 0000000000000400
