“There are indications from Google Threat Analysis Group that CVE-2024-43047 may be under limited, targeted exploitation. Patches for the issue affecting FASTRPC driver have been made available to OEMs together with a strong recommendation to deploy the update on affected devices as soon as possible,” Qualcomm wrote in its security bulletin.
A serious vulnerability (CVE-2024-33066, CVSS 9.8) in the WLAN Resource Manager could let attackers remotely execute harmful code, risking a complete device takeover. This issue, caused by improper input validation, allows memory corruption by redirecting log files. Affected chipsets include Immersive Home Platforms, IPQ series, QCA series, and Snapdragon X65 5G Modem-RF systems.
A high-severity vulnerability (CVE-2024-23369) in the HLOS (Hardware Abstraction Layer Operating System) allows local attackers to exploit memory corruption by manipulating FRS/UDS buffers. This affects Snapdragon mobile platforms, FastConnect series, and QCA series.
The October bulletin discusses various vulnerabilities in open-source software, including a buffer over-read issue in WLAN Host Communication (CVE-2024-33064) that may lead to denial of service or sensitive information leaks.
Qualcomm urges OEMs to quickly apply necessary patches to protect users. Users should update their devices to the latest firmware and check with their manufacturers about patch status for their specific models.
