CVE-2025-27041 is a buffer over-read vulnerability classified under CWE-126 found in Qualcomm Snapdragon platforms and associated chipsets. The vulnerability arises during the processing of video packets received from video firmware, leading to a transient denial of service (DoS) condition. Specifically, the flaw allows an attacker with local privileges to cause the system to read beyond the intended buffer boundaries, which can disrupt normal processing and cause temporary unavailability of affected components. The affected products include a broad range of Qualcomm Snapdragon mobile platforms (e.g., Snapdragon 660, 680, 888 series), automotive modems, FastConnect wireless subsystems, and various Qualcomm connectivity chipsets. The CVSS v3.1 base score is 5.5 (medium severity), with attack vector local (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), no impact on confidentiality or integrity (C:N/I:N), but high impact on availability (A:H). No public exploits are known at this time, and Qualcomm has not yet published patches. The vulnerability's root cause is a buffer over-read during video packet processing, which can cause transient system instability or crashes affecting availability but not data confidentiality or integrity. This vulnerability primarily threatens devices that rely on Qualcomm Snapdragon chipsets for video processing, including smartphones, automotive infotainment systems, and IoT devices.

For European organizations, this vulnerability poses a risk primarily to availability of devices utilizing affected Qualcomm Snapdragon platforms. Mobile devices, automotive systems, and IoT infrastructure relying on these chipsets could experience transient denial of service conditions, potentially disrupting business operations, communications, or critical automotive functions. Enterprises with large fleets of mobile devices or automotive manufacturers integrating Snapdragon-based modems and video processing units may face operational interruptions. Although the vulnerability does not compromise data confidentiality or integrity, availability impacts can degrade user experience and operational reliability. Given the widespread use of Qualcomm Snapdragon in European consumer electronics and automotive sectors, the disruption could affect end-users and industrial applications. The requirement for local privileges limits remote exploitation, but insider threats or compromised devices could trigger the DoS. The lack of known exploits reduces immediate risk, but organizations should prepare for potential future exploitation attempts.

Organizations should monitor Qualcomm’s security advisories for patches addressing CVE-2025-27041 and apply them promptly once available. Until patches are released, restrict access to video firmware interfaces and limit local user privileges to trusted personnel only. Employ device hardening practices to reduce the attack surface, including disabling unnecessary video processing features if feasible. Implement monitoring to detect abnormal device behavior or crashes indicative of exploitation attempts. For automotive and IoT deployments, ensure secure firmware update mechanisms to facilitate timely patching. Network segmentation can help isolate affected devices to contain potential disruptions. Additionally, conduct security awareness training to mitigate insider threats that could exploit local privilege requirements. Collaborate with device vendors to confirm affected hardware and firmware versions and validate remediation status. Finally, consider deploying endpoint detection and response (EDR) solutions capable of identifying anomalous local activities related to video firmware processing.
