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.

No CVSS v4.0

No CVSS v3.1

No CVSS v3.0

No CVSS v2
