CVE-2022-26765 is a medium-severity vulnerability discovered in multiple Apple operating systems, including macOS Monterey, iOS, iPadOS, tvOS, and watchOS. This vulnerability allows malicious actors to exploit a race condition, which can potentially lead to unauthorized access or manipulation of system memory. The CVSS base score for this vulnerability is 4.7, indicating a medium level of risk.
The vulnerability is particularly concerning because it allows an attacker with arbitrary read and write capabilities to bypass Pointer Authentication. This can have serious implications for the integrity of the affected systems, especially in environments where sensitive data is processed.
Organizations using affected Apple products should prioritize patching this vulnerability. Apple has released fixes in the latest versions of the affected operating systems, including watchOS 8.6, tvOS 15.5, macOS Monterey 12.4, iOS 15.5, and iPadOS 15.5. Immediate action is necessary to mitigate potential exploitation.
Given the nature of this vulnerability, organizations should conduct thorough assessments of their environments to ensure that all impacted systems are updated to mitigate the risk of exploitation. Regular monitoring and security audits are also advised to detect any potential indicators of compromise.
Vulnerability Details
Apple has identified CVE-2022-26765 as a race condition that affects multiple products including macOS, iPadOS, iOS, tvOS, and watchOS. The issue was addressed with improved state handling, and the vulnerability has been documented in their product security advisories.
The vulnerability's CVSS score is 4.7, classified as medium severity. This score reflects the potential impact on integrity due to the vulnerability, as it allows unauthorized manipulation of data.
The affected products include versions of iOS, iPadOS, macOS, tvOS, and watchOS prior to the respective patches. It is classified under CWE-362, which pertains to race conditions.
Technical Analysis
The root cause of CVE-2022-26765 is a race condition, which occurs when two or more processes can access shared data and they try to change it at the same time. This condition can lead to erratic behavior in applications and operating systems, especially if the state handling is not properly synchronized.
The attack vector for this vulnerability is local, meaning that an attacker must have physical or local access to the device. The complexity of exploiting this vulnerability is assessed as high, requiring specific conditions to be met for successful exploitation.
Privileges required to exploit this vulnerability are low, indicating that an unprivileged user may be able to perform actions that lead to exploitation. No user interaction is required, which increases the likelihood of successful attacks.
In terms of impact, the confidentiality impact is none, while integrity is rated as high. This indicates that while sensitive information may not be directly exposed, the integrity of the system can be compromised, potentially allowing unauthorized modifications.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access and manipulation of system data, leading to integrity violations. The blast radius for this vulnerability is significant, as it affects multiple Apple products across various user environments.
Organizations should assess the urgency of this vulnerability based on the CVSS score of 4.7. Given that exploitation requires local access, the immediate risk may vary depending on the operational environment. However, it is advisable to prioritize remediation efforts to maintain system integrity.
