CWE-119Published: September 5, 2023· Updated: Jun 17, 2026
Official Description
Memory corruption in WLAN Firmware while parsing receieved GTK Keys in GTK KDE.
Risk Analysis
Qualcomm FastConnect firmware is vulnerable to memory corruption when parsing GTK keys. This critical flaw allows a remote attacker to potentially execute arbitrary code or cause a system crash.
No public exploit is known, and it is not in the CISA KEV. It is remotely exploitable with low attack complexity.
Users should apply the latest firmware updates provided by the device manufacturer for the affected FastConnect components.
Technical Analysis
CVE-2023-28581 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
