CVE-2024-49841 is a vulnerability classified under CWE-390, indicating detection of an error condition without appropriate action, specifically within Qualcomm Snapdragon chipsets. The issue arises from incorrect error code handling during memory assignment to a headless peripheral virtual machine, resulting in memory corruption. This memory corruption can be exploited to achieve unauthorized code execution or escalate privileges, impacting confidentiality, integrity, and availability of the system. The vulnerability affects a wide array of Qualcomm products, including multiple Snapdragon mobile platforms (e.g., SD 8 Gen1 5G, SD 865 5G, SD 888 5G), FastConnect wireless subsystems, compute platforms (e.g., Snapdragon 8cx series), automotive platforms, and various wireless connectivity modules. The flaw requires local privileges (AV:L) and low attack complexity (AC:L), with no user interaction needed (UI:N), and the scope remains unchanged (S:U). The CVSS v3.1 base score is 7.8, indicating high severity, with high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits are known, the extensive list of affected devices and platforms suggests a broad potential impact. The vulnerability was published on May 6, 2025, and is recognized by CISA as enriched intelligence. No patches are currently linked, indicating that mitigation may depend on forthcoming vendor updates.

The impact of CVE-2024-49841 is significant due to the extensive range of affected Qualcomm Snapdragon platforms used globally in smartphones, tablets, automotive systems, IoT devices, and compute platforms. Successful exploitation can lead to memory corruption, enabling attackers with local access to execute arbitrary code, escalate privileges, or cause denial of service. This compromises device confidentiality, integrity, and availability, potentially allowing attackers to bypass security controls, access sensitive data, or disrupt critical services. Given the prevalence of Snapdragon chipsets in consumer and enterprise devices, the vulnerability poses a risk to millions of devices worldwide. In automotive and IoT contexts, exploitation could affect safety-critical systems, increasing the risk of physical harm or operational disruption. The requirement for local privileges limits remote exploitation but does not eliminate risk, especially in environments where attackers can gain local access through other means (e.g., malware, insider threats). The absence of known exploits in the wild currently reduces immediate risk but does not preclude future exploitation once exploit code becomes available.

1. Monitor Qualcomm’s official security advisories and apply patches promptly once released for all affected Snapdragon platforms and related components. 2. Implement strict access controls to limit local user privileges and prevent unauthorized local access to devices running vulnerable Snapdragon chipsets. 3. Employ endpoint detection and response (EDR) solutions to monitor for unusual memory operations or VM-related anomalies indicative of exploitation attempts. 4. For enterprise and automotive deployments, enforce device hardening policies and restrict installation of untrusted applications that could leverage local access to exploit this vulnerability. 5. Coordinate with device manufacturers and vendors to ensure firmware and software updates incorporate fixes for this vulnerability. 6. Conduct regular security audits and penetration testing focused on local privilege escalation vectors to identify potential exploitation paths. 7. Educate users and administrators about the risks of local access attacks and the importance of timely updates. 8. Where patching is delayed, consider isolating vulnerable devices from sensitive networks to reduce potential impact.
