CVE-2025-27059 is a vulnerability classified under CWE-823 (Use of Out-of-range Pointer Offset) affecting Qualcomm Snapdragon platforms. The issue arises from improper handling of pointer offsets during Secure Channel Manager (SCM) calls, leading to memory corruption. This memory corruption can be exploited by an attacker with low privileges and local access to the device to execute arbitrary code or cause denial of service. The vulnerability impacts a broad range of Snapdragon platforms, including Immersive Home 214, 216, 316, 318 platforms, and multiple QCN series chipsets (e.g., QCN6023, QCN9000, QCN9274). The CVSS v3.1 base score is 8.8, indicating a high severity with the vector AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H, meaning the attack requires local access with low complexity, no user interaction, and results in high impact on confidentiality, integrity, and availability with scope change. The flaw allows privilege escalation and potentially full system compromise. No patches are currently linked, and no exploits are known in the wild, but the vulnerability is publicly disclosed and should be considered critical for affected environments. The affected platforms are commonly used in networking equipment, IoT devices, and embedded systems, making this a significant threat to infrastructure relying on Qualcomm Snapdragon chipsets.

The vulnerability allows an attacker with local access and low privileges to corrupt memory during SCM calls, leading to arbitrary code execution with elevated privileges. This can result in full system compromise, data leakage, unauthorized control over device functions, and denial of service. Organizations using affected Snapdragon platforms in critical infrastructure such as networking equipment, IoT devices, and embedded systems face risks including disruption of services, exposure of sensitive data, and potential lateral movement within networks. The broad range of affected chipsets increases the attack surface, especially in environments where physical or local access controls are weak. The scope change in the CVSS vector indicates that the exploit can affect components beyond the initially vulnerable module, amplifying the potential damage. The absence of known exploits in the wild currently reduces immediate risk but the public disclosure may lead to rapid development of exploit code, increasing urgency for mitigation.

Organizations should monitor Qualcomm’s advisories for official patches and apply them promptly once available. Until patches are released, restrict local access to devices running affected Snapdragon platforms by enforcing strict physical security and network segmentation to limit exposure. Employ host-based intrusion detection systems to monitor for abnormal SCM call behavior or memory corruption indicators. Conduct regular firmware and software integrity checks to detect unauthorized modifications. For IoT and embedded devices, ensure secure boot and trusted execution environments are enabled to mitigate exploitation impact. Collaborate with device vendors to confirm patch availability and deployment timelines. Additionally, implement strict privilege management to minimize the number of users with local access and privileges on vulnerable devices. Maintain up-to-date asset inventories to identify all affected devices in the environment for targeted remediation.
