CVE-2025-27041 is a buffer over-read vulnerability classified under CWE-126 found in multiple Qualcomm Snapdragon chipsets and related platforms. The flaw occurs during the processing of video packets by the video firmware, where improper bounds checking leads to reading beyond the allocated buffer. This can cause a transient denial of service (DoS) condition, disrupting video processing capabilities temporarily. The vulnerability affects a broad range of Qualcomm products, including mobile platforms like Snapdragon 660, 680, 888 series, automotive modems, and various wireless connectivity chips (e.g., FastConnect 6900, QCA series). Exploitation requires local privileges (AV:L) with low attack complexity (AC:L) and no user interaction (UI:N), but privileges are necessary to trigger the flaw. The impact is limited to availability (A:H), with no confidentiality or integrity compromise. No public exploits have been reported yet, and Qualcomm has not published patches at the time of disclosure. The vulnerability was reserved in February 2025 and published in October 2025, indicating a recent discovery. The broad product impact suggests that many devices incorporating these chipsets could be vulnerable, including smartphones, automotive systems, and IoT devices. The transient DoS could disrupt critical services relying on video processing or connectivity. Given the complexity and requirement for local access, exploitation is less likely remotely but remains a concern for targeted attacks or insider threats.

For European organizations, the primary impact of CVE-2025-27041 is the potential for transient denial of service in devices using affected Qualcomm Snapdragon chipsets. This could disrupt video processing functions in smartphones, automotive infotainment systems, and wireless communication devices. Critical sectors such as automotive manufacturing, transportation, telecommunications, and public safety could experience operational interruptions. In automotive contexts, disruption of video firmware could affect driver assistance systems or in-vehicle entertainment, potentially impacting safety and user experience. Telecommunications providers using affected modems might face service degradation. The requirement for local privileges limits remote exploitation, but insider threats or compromised devices could trigger the vulnerability. The widespread use of Qualcomm Snapdragon in consumer and industrial devices across Europe means the scope is broad, potentially affecting millions of endpoints. The absence of known exploits reduces immediate risk, but the vulnerability could be leveraged in targeted attacks or combined with other exploits. Organizations relying on video collaboration platforms or embedded systems with these chipsets should prioritize assessment and remediation to avoid service disruptions.

1. Monitor Qualcomm and device vendor advisories closely for official patches or firmware updates addressing CVE-2025-27041 and apply them promptly once available. 2. Implement strict access controls to limit local privilege escalation and reduce the risk of an attacker gaining the necessary local access to exploit the vulnerability. 3. Employ endpoint detection and response (EDR) solutions to monitor for anomalous behavior related to video firmware or chipset operations that could indicate exploitation attempts. 4. For automotive and embedded systems, coordinate with OEMs to schedule firmware updates and validate system stability post-patching. 5. Conduct regular security audits and vulnerability assessments on devices using affected Snapdragon chipsets to identify and remediate potential exposure. 6. Educate internal staff about the risks of local privilege misuse and enforce least privilege principles to minimize insider threat vectors. 7. Where possible, isolate critical systems using affected chipsets from untrusted networks or users to reduce attack surface. 8. Maintain robust incident response plans to quickly address any transient DoS events impacting video processing or connectivity services.
