Stack-based Buffer Overflow

CVE-2023-44431

High
8/10

Summary

A stack-based buffer overflow vulnerability exists in BlueZ's handling of the Audio/Video Remote Control Profile (AVRCP), allowing network-adjacent attackers to execute arbitrary code via Bluetooth. Exploitation requires user interaction, such as connecting to a malicious Bluetooth device. The vulnerability occurs due to insufficient validation of user-supplied data length before copying it into a fixed-length stack-based buffer. An attacker can exploit this flaw to execute code with root privileges.
