Linux Distros Unpatched Vulnerability : CVE-2026-16473

medium Nessus Plugin ID 329464

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- 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. (CVE-2026-16473)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
