What it is

In 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.
