Description
Memory corruption during video playback when video session open fails with time out error
AI Analyst Comment
Remediation
Apply vendor security updates immediately. Monitor for exploitation attempts and review access logs.
Description Summary:
A use-after-free vulnerability in Qualcomm Snapdragon hardware allows for memory corruption during video playback if a session open fails due to a timeout error.
Executive Summary:
A critical memory corruption vulnerability in Qualcomm Snapdragon chipsets could allow local attackers to gain elevated privileges or execute arbitrary code.
Vulnerability Details
CVE-ID: CVE-2025-27063
Affected Software: Qualcomm Snapdragon
Affected Versions: CSRA6620, CSRA6640, FastConnect 6200, FastConnect 6700, FastConnect 6800, FastConnect 6900, FastConnect 7800, Flight RB5 5G Platform
Vulnerability: The flaw is a use-after-free (CWE-416) condition triggered during video session initialization. An attacker with local access and low privileges can exploit this memory corruption when a session open request fails due to a timeout, potentially leading to unauthorized system impact.
Business Impact
The vulnerability carries a CVSS score of 7.8, indicating a high severity risk. Successful exploitation could allow a local attacker to compromise the integrity, availability, and confidentiality of the affected hardware platform, potentially leading to full system compromise or persistent unauthorized access.
Remediation Plan
Immediate Action: Review the official Qualcomm December 2025 security bulletin and apply the vendor provided firmware or software updates to all affected Snapdragon platforms.
Proactive Monitoring: Monitor system logs for unexpected video playback crashes or abnormal service behavior that may indicate an attempt to trigger the timeout condition.
Compensating Controls: Since this is a hardware-level vulnerability, minimize local user access to the affected devices and ensure that only trusted applications are permitted to interface with the video hardware.
Exploitation Status
Public Exploit Available: No
Analyst Notes: As of December 18, 2025, there is no public information indicating active exploitation or a public proof-of-concept for this vulnerability. The flaw requires local, low-privileged access to the device, which limits the attack surface to users or malicious applications already present on the system.
Analyst Recommendation
Given the potential for complete system impact via memory corruption, immediate action is required to patch affected Qualcomm Snapdragon components. Organizations should prioritize firmware updates for all deployed hardware listed in the vendor advisory to eliminate the risk of exploitation.
