In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: validate RX band_idx before dereferencing phys[]
band_idx comes from a 2-bit descriptor field (0-3) and was used directly
to index dev->mt76.phys[] (size __MT_MAX_BAND == 3) and dereference the
result. A corrupt or reserved descriptor value could index out of bounds
or hit a NULL phy on parts with fewer bands. Reject invalid band indices,
mirroring mt7996_rx_get_wcid().
