Sbc: sbc: heap out-of-bounds read via crafted sbc audio frame

Title source: cna
STIX 2.1

Description

A flaw was found in the sbc library (BlueZ SBC codec). An off-by-one error in the SBC frame decoder allows a crafted audio payload to trigger a one-byte heap out-of-bounds read. This could allow an adjacent attacker streaming Bluetooth audio to read a single byte of adjacent heap memory.
