Description
This vulnerability involves the mt76 wireless driver component, specifically the mt7996 chipset, where the RX band index is not properly validated before dereferencing the phys[] array. This could potentially lead to out-of-bounds memory access or other unintended behavior. The affected software versions are exactly 3.0 and 4.0. No CVSS score or detailed impact information is provided, and there are no known exploits in the wild at this time.
