CVE-2026-98247
– Non évaluéeDescription
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.
