Critical Qualcomm Chipset Vulnerabilities Enable Remote Code Execution
Qualcomm Technologies has recently disclosed multiple critical vulnerabilities within its proprietary and open-source software, posing significant security risks to a wide array of devices powered by Snapdragon processors. These vulnerabilities, if exploited, could allow attackers to execute arbitrary code remotely, leading to potential data breaches, device control, and system instability.
Overview of Critical Vulnerabilities
The most severe of these vulnerabilities is identified as CVE-2026-25254, which carries a Common Vulnerability Scoring System (CVSS) score of 9.8, indicating its critical nature. This flaw resides in the Qualcomm Software Center and stems from improper authorization mechanisms. An unauthenticated attacker can exploit this vulnerability via the SocketIO interface to achieve remote code execution, potentially compromising the entire system.
Another critical vulnerability, CVE-2026-25293, with a CVSS score of 9.6, affects the Power Line Communication (PLC) firmware. This issue arises from a buffer overflow caused by incorrect authorization checks, enabling remote attackers to execute arbitrary code without requiring user interaction.
Additional High-Severity Vulnerabilities
Beyond these critical flaws, Qualcomm has addressed several high-severity vulnerabilities that could lead to local privilege escalation or system instability:
– CVE-2026-25262: A write-what-where condition in the Primary Bootloader, leading to memory corruption when processing crafted ELF files.
– CVE-2025-47401 and CVE-2025-47403: Buffer over-read vulnerabilities in the WLAN HAL and firmware, respectively, allowing remote attackers to trigger transient Denial-of-Service (DoS) conditions via buffer overruns during channel configuration or wireless roaming.
