CVE-2024-39833 is a vulnerability identified in Intel(R) QuickAssist Technology (QAT) software prior to version 2.3.0. The issue stems from an uncontrolled search path, which means the software does not properly validate or restrict the directories it searches for certain resources or executables. This flaw can be exploited by an authenticated user with local access to the system to escalate their privileges beyond their assigned level. The vulnerability requires the attacker to have at least low-level privileges and some user interaction, such as executing a crafted process or script locally. The CVSS 4.0 base score of 5.4 reflects a medium severity, with attack vector limited to local access (AV:L), high attack complexity (AC:H), and requiring privileges (PR:L) and user interaction (UI:A). The impact on confidentiality, integrity, and availability is high, indicating that successful exploitation could lead to significant compromise of system security. The vulnerability does not affect network attack vectors and is not known to be exploited in the wild at this time. Intel QAT is widely used in accelerating cryptographic and compression workloads in data centers, cloud environments, and enterprise hardware, making this vulnerability relevant to organizations relying on these technologies. The lack of a patch link in the provided data suggests that remediation involves upgrading to version 2.3.0 or later once available. The vulnerability was reserved in June 2024 and published in May 2025, indicating a recent disclosure.

The potential impact of CVE-2024-39833 is significant for organizations utilizing Intel QAT software in their infrastructure. Successful exploitation allows a local authenticated user to escalate privileges, potentially gaining administrative or root-level access. This can lead to unauthorized access to sensitive data, modification or disruption of critical cryptographic operations, and compromise of system integrity and availability. In environments where Intel QAT accelerates cryptographic functions, such as secure communications, VPNs, or cloud services, this vulnerability could undermine the security guarantees of these systems. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk in multi-user or shared environments. Attackers who gain low-level access through other means could leverage this vulnerability to deepen their foothold. The absence of known exploits in the wild reduces immediate risk but does not preclude future exploitation. Organizations with high-value targets or sensitive data processed via Intel QAT are particularly at risk, as privilege escalation can facilitate lateral movement and persistent compromise.

To mitigate CVE-2024-39833, organizations should prioritize upgrading Intel QAT software to version 2.3.0 or later as soon as it becomes available. Until a patch is applied, restrict local access to systems running vulnerable QAT versions by enforcing strict user account controls and limiting the number of users with local login privileges. Implement robust monitoring and logging of local user activities to detect suspicious behavior indicative of privilege escalation attempts. Employ application whitelisting or execution control mechanisms to prevent unauthorized or unexpected binaries from running in directories involved in the search path. Conduct regular audits of system configurations to identify and remediate insecure search path settings or permissions. Additionally, consider isolating QAT-enabled systems within segmented network zones to reduce exposure. Security teams should stay informed on Intel advisories for any updated patches or mitigation guidance. Finally, incorporate this vulnerability into incident response plans to enable rapid containment if exploitation is detected.
