CVE-2026-18748The Bluetooth Classic A2DP host stores a codec Information Element (IE) in struct bt_a2dp_codec_ie, a one-byte len field plus a fixed 8-byte codec_ie[] array Executive summary A flaw in the Bluetooth Classic A2DP host component can let a paired Bluetooth device read a bounded region of nearby memory on the affected device. The advisory describes this as an information disclosure issue, and it does not state a severity score. The advisory describes a fix that makes the length limit configurable and rejects oversized codec data, but it does not state a fixed version number. Technical summary The vulnerability is an out-of-bounds read caused by a length field that is not reconciled with a fixed 8-byte codec Information Element buffer in struct bt_a2dp_codec_ie. When an AVDTP peer sends a longer codec IE in SET_CONFIGURATION, only 8 bytes are copied but the full length is stored, and later GET_CONFIGURATION responses read up to about 245 bytes past the array and send them to the peer. Exploitation requires CONFIG_BT_CLASSIC and CONFIG_BT_A2DP, a peer that has completed pairing, and a local endpoint registered for a non-SBC codec, although the bt_a2dp_get_config_cb() path has no such gate. The advisory states there is no out-of-bounds write. Affected version numbers are not stated, fixed version numbers are not stated, and no workaround is stated beyond the described fix. Detection guidance is not stated. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
