CVE-2023-27349
Description
A vulnerability was found in the BlueZ Audio Profile AVRCP, stemming from the improper validation of array indices. This flaw resides in the AVRCP protocol handling and arises due to inadequate validation of user-supplied data. Consequently, it may lead to writing beyond the bounds of an allocated buffer. This flaw possibly allows a network-adjacent attacker to execute code within the root context via Bluetooth.
Statement
This vulnerability is considered moderate due to its potential impact stemming from improper validation of array indices within the BlueZ Audio Profile AVRCP implementation. The inadequate validation of user-supplied data could result in buffer overflow, enabling a network-adjacent attacker to execute code with root privileges via Bluetooth, contingent upon specific conditions being met.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
