A memory corruption vulnerability in Qualcomm Snapdragon chipsets could allow a local attacker with low privileges to gain elevated control over the device.

This is a stack-based buffer overflow (CWE-121) occurring during dynamic channel switching. It allows an attacker with low-level local access to trigger memory corruption when the system processes invalid HT40 channel layout data.

With a CVSS score of 8.8, this vulnerability poses a significant risk to the integrity and availability of devices using affected Qualcomm hardware. Successful exploitation could lead to total system impact, including privilege escalation and the execution of arbitrary code, which is particularly dangerous for enterprise-grade networking and mobile hardware.

Immediate Action: Check the Qualcomm July 2026 Security Bulletin for device-specific firmware updates and apply the necessary patches to your hardware.

Proactive Monitoring: Monitor for unexpected system reboots, stability issues, or performance degradation on affected hardware, which may indicate memory corruption events.

Compensating Controls: Restrict physical or local access to affected hardware components to minimize the attack surface, as the vulnerability requires local access to exploit.

Public Exploit Available: false

Hardware-level vulnerabilities like this one are difficult to mitigate without vendor-supplied firmware updates. Organizations utilizing affected Qualcomm Snapdragon platforms must coordinate with their hardware vendors to verify the availability of patched firmware and schedule deployment immediately.
