What it is

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_codec: validate vendor codec count length

The Read Local Supported Codecs parsers consume the variable-sized

standard codec array before parsing the vendor codec count. Although the

initial reply-size check includes a vendor count byte in the fixed layout,

it does not guarantee that the byte remains after the standard codec array.

If a controller reply ends immediately after that array, calculating the

vendor codec array size reads vnd_codecs->num beyond the skb data. Use

skb_pull_data() to validate and consume each codec header before using its

count in both command variants.
