CVE-2026-16473

Summary

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.

Workarounds

There is no practical mitigation short of disabling Bluetooth A2DP audio decoding entirely. The SBC codec is mandatory for A2DP and the decode path is invoked automatically on incoming Bluetooth audio streams.
