DescriptionIn the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: bound TLV walk in mt7996_mcu_get_chip_config The response TLV loop advanced by tlv->len without a minimum, so a theoretical firmware response containing a zero-length TLV could spin forever, hanging the CPU during device probe. The u32 payload was also read without bounds checking. Reject a short fixed field, stop on a TLV whose length underruns the header or overruns the skb.
