CVE-2022-27674: NA in AMD AMD μProf
Insufficient validation in the IOCTL input/output buffer in AMD μProf may allow an attacker to bypass bounds checks potentially leading to a Windows kernel crash resulting in denial of service.
AI Analysis
Technical Summary
CVE-2022-27674 is a high-severity vulnerability affecting AMD's performance profiling tool, AMD μProf, across multiple platforms including Windows, Linux, and FreeBSD. The root cause is insufficient validation of input/output buffers in the IOCTL (Input Output Control) interface. This lack of proper bounds checking allows an attacker to craft malicious IOCTL requests that can bypass normal validation mechanisms. Exploiting this flaw can lead to a Windows kernel crash, resulting in a denial of service (DoS) condition. The vulnerability is classified under CWE-20, which pertains to improper input validation. Notably, the CVSS v3.1 score is 7.5, reflecting a high severity primarily due to the potential for complete availability disruption without requiring any privileges or user interaction. The attack vector is network or remote (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). Although the vulnerability does not impact confidentiality or integrity, the ability to cause a kernel-level crash can severely disrupt system operations, especially on critical infrastructure or enterprise environments where AMD μProf is deployed for performance monitoring and profiling. There are no known exploits in the wild at the time of publication, and no patches have been linked yet, indicating that mitigation may rely on vendor updates or workarounds once available.
Potential Impact
For European organizations, the impact of this vulnerability can be significant, particularly in sectors relying on AMD hardware and AMD μProf for performance analysis and system diagnostics, such as technology firms, research institutions, and data centers. A successful exploitation can cause system crashes leading to downtime, loss of productivity, and potential disruption of critical services. In environments where uptime and reliability are paramount, such as financial services, healthcare, and industrial control systems, the denial of service could have cascading effects on business operations and service delivery. Although the vulnerability does not allow data theft or system takeover, the disruption caused by kernel crashes could necessitate emergency response and recovery efforts, increasing operational costs. Additionally, the lack of required privileges or user interaction lowers the barrier for attackers, potentially enabling automated or remote attacks against vulnerable systems.
Mitigation Recommendations
To mitigate this vulnerability, European organizations should: 1) Monitor AMD's official channels for patches or updates addressing CVE-2022-27674 and apply them promptly once available. 2) Restrict access to AMD μProf interfaces, especially IOCTL calls, by enforcing strict access controls and limiting usage to trusted administrators or systems. 3) Employ network segmentation and firewall rules to limit exposure of systems running AMD μProf to untrusted networks or users. 4) Implement robust monitoring and alerting for unusual IOCTL activity or system crashes that could indicate exploitation attempts. 5) Consider temporarily disabling AMD μProf if it is not essential for operations until a patch is released. 6) Conduct regular system integrity checks and maintain up-to-date backups to facilitate rapid recovery in case of denial of service incidents. These steps go beyond generic advice by focusing on controlling the attack surface related to the vulnerable component and preparing for incident response.
