CVE-2022-25676: Buffer Over-read in Video in Qualcomm, Inc. Snapdragon Auto, Snapdragon Compute, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Wearables
Information disclosure in video due to buffer over-read while parsing avi files in Snapdragon Auto, Snapdragon Compute, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Wearables
AI Analysis
Technical Summary
CVE-2022-25676 is a medium-severity vulnerability identified in multiple Qualcomm Snapdragon platforms, including Snapdragon Auto, Compute, Consumer IoT, Industrial IoT, Mobile, and Wearables. The vulnerability arises from a buffer over-read condition during the parsing of AVI video files. Specifically, the flaw is a buffer over-read (CWE-125) in the video processing component, which can lead to information disclosure. When an affected device processes a specially crafted AVI file, the video parser reads beyond the allocated buffer boundaries, potentially leaking sensitive memory contents. This vulnerability affects a broad range of Qualcomm chipsets and platforms, including many Snapdragon mobile SoCs (e.g., SD 8 Gen1 5G, SD888, SD865 5G), IoT modules, and automotive processors. The flaw does not require authentication or elevated privileges to exploit, but it does require the victim device to process a malicious AVI file, which implies some level of user interaction or file delivery. No known public exploits have been reported in the wild as of the published date (November 15, 2022), and Qualcomm has not provided official patches linked in the provided data. The vulnerability could be triggered through media playback or processing applications that handle AVI files on affected devices. The broad affected product list indicates a widespread exposure across consumer smartphones, IoT devices, automotive systems, and wearable technology utilizing Qualcomm Snapdragon chipsets. The root cause is improper bounds checking in the video parser, leading to reading memory outside intended buffers, which can leak sensitive data from device memory to an attacker-controlled output.
Potential Impact
For European organizations, the impact of CVE-2022-25676 can be significant, especially for sectors relying heavily on Qualcomm Snapdragon-based devices, such as automotive manufacturers, IoT deployments, mobile workforce, and wearable technology users. The information disclosure could lead to leakage of sensitive data residing in memory, including cryptographic keys, personal user data, or proprietary information processed by the device. In automotive contexts, compromised infotainment or telematics units could expose vehicle telemetry or user privacy data. Industrial IoT devices affected could leak operational data or credentials, potentially facilitating further attacks. Although the vulnerability does not directly enable code execution or denial of service, the confidentiality breach can be leveraged for targeted espionage or lateral movement within networks. The requirement for processing a malicious AVI file means that attackers might exploit this via phishing, malicious media files embedded in emails, or compromised websites delivering crafted video content. European organizations with extensive mobile device fleets, connected vehicles, or IoT infrastructure using Qualcomm Snapdragon platforms are at risk. The lack of known exploits reduces immediate threat but does not eliminate risk, especially as attackers may develop exploits over time. The broad range of affected chipsets means that many consumer and enterprise devices in Europe could be vulnerable, impacting data privacy compliance and operational security.
Mitigation Recommendations
Given the absence of official patches linked in the provided data, European organizations should adopt a multi-layered mitigation approach: 1) Restrict or monitor the intake of untrusted AVI video files on devices using affected Qualcomm Snapdragon platforms, especially in enterprise and automotive environments. 2) Employ endpoint security solutions capable of detecting and blocking malformed media files or anomalous video parsing behavior. 3) Where possible, update device firmware and software to the latest versions provided by device manufacturers or Qualcomm, as patches may be released post-disclosure. 4) Implement strict media file handling policies, including disabling automatic playback of AVI files or sandboxing media processing applications. 5) For automotive and IoT deployments, ensure network segmentation and strict access controls to limit exposure of vulnerable devices to untrusted sources. 6) Conduct regular security audits and vulnerability assessments focusing on media processing components. 7) Educate users and administrators about the risks of opening untrusted media files and encourage vigilance against phishing or social engineering attempts delivering malicious AVI files. 8) Collaborate with device vendors to obtain timely updates and verify patch status for affected hardware. These targeted mitigations go beyond generic advice by focusing on controlling the attack vector (malicious AVI files) and hardening media processing workflows specific to the vulnerability.
