CVE-2022-25681: Improper Access Control in KERNEL in Qualcomm, Inc. Snapdragon Auto, Snapdragon Compute, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile
Possible memory corruption in kernel while performing memory access due to hypervisor not correctly invalidated the processor translation caches in Snapdragon Auto, Snapdragon Compute, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile
AI Analysis
Technical Summary
CVE-2022-25681 is a vulnerability classified as an improper access control issue within the kernel of Qualcomm Snapdragon platforms, including Snapdragon Auto, Compute, Consumer IoT, Industrial IoT, and Mobile product lines. The root cause lies in the hypervisor's failure to correctly invalidate processor translation caches during memory access operations. This flaw can lead to possible memory corruption in the kernel, which is a critical component responsible for managing hardware resources and enforcing security boundaries. The vulnerability affects a broad range of Qualcomm chipsets and modules, including but not limited to AQT1000, QCA series (e.g., QCA6174A, QCA6390), SD series (e.g., SD 8 Gen1 5G, SD888), and WCN series wireless connectivity chips. The improper invalidation of translation caches can allow unauthorized access or modification of kernel memory, potentially enabling privilege escalation or arbitrary code execution at the kernel level. This type of vulnerability is categorized under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer), indicating risks of buffer overflows or memory corruption. Although no known exploits are currently reported in the wild, the extensive range of affected devices, including automotive, industrial IoT, and mobile platforms, underscores the importance of timely mitigation. The vulnerability was publicly disclosed on December 13, 2022, and is rated with medium severity by the vendor, reflecting a balance between exploit complexity and potential impact.
Potential Impact
For European organizations, the impact of CVE-2022-25681 can be significant due to the widespread deployment of Qualcomm Snapdragon chipsets across various sectors. In the automotive industry, Snapdragon Auto platforms are integrated into advanced driver-assistance systems (ADAS) and infotainment systems; exploitation could lead to unauthorized control or disruption of vehicle systems, posing safety risks and operational downtime. Industrial IoT devices using Snapdragon Industrial IoT platforms are critical for manufacturing automation and infrastructure monitoring; a successful attack could compromise operational integrity, leading to production halts or safety incidents. Consumer IoT and mobile devices are ubiquitous in enterprise environments, and kernel-level compromise could facilitate lateral movement, data exfiltration, or persistent footholds within corporate networks. The memory corruption nature of the vulnerability means confidentiality, integrity, and availability of affected systems could be compromised. Although exploitation requires kernel-level access and is non-trivial, the broad scope of affected devices increases the attack surface. European organizations relying heavily on Qualcomm-powered devices, especially in automotive manufacturing, critical infrastructure, and telecommunications, face elevated risks. Additionally, the lack of known exploits currently provides a window for proactive defense but also necessitates vigilance given the potential for future weaponization.
Mitigation Recommendations
Given the absence of publicly available patches at the time of disclosure, European organizations should implement a multi-layered mitigation strategy: 1) Engage with device and chipset vendors to obtain and deploy firmware or software updates as soon as they become available, prioritizing automotive and industrial IoT devices. 2) Employ strict network segmentation to isolate vulnerable devices, limiting exposure to untrusted networks and reducing the attack surface. 3) Monitor kernel-level logs and system behavior for anomalies indicative of memory corruption or privilege escalation attempts, using advanced endpoint detection and response (EDR) tools tailored for embedded and IoT environments. 4) Implement strict access controls and minimize privileged access to devices running affected Snapdragon platforms, enforcing the principle of least privilege. 5) For organizations deploying hypervisors or virtualization on Snapdragon platforms, ensure hypervisor configurations follow best practices to mitigate cache invalidation issues and consider additional runtime protections such as kernel address space layout randomization (KASLR) and memory protection extensions. 6) Conduct regular security assessments and penetration testing focused on embedded and IoT devices to identify potential exploitation paths. 7) Maintain up-to-date inventories of affected devices to prioritize patching and risk management efforts effectively.
