CVE-2024-40815
Published: 29 July 2024
Summary
CVE-2024-40815 is a high-severity Race Condition (CWE-362) vulnerability in Apple Macos. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 8.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
A race condition vulnerability addressed through additional validation affects multiple Apple operating systems, including iOS 17.6, iPadOS 17.6, macOS Sonoma 14.6, macOS Ventura 13.6.8, tvOS 17.6, and watchOS 10.6. The flaw is tracked under CWE-362 and CWE-352 and carries a CVSS 3.1 score of 7.5, reflecting high impact on confidentiality, integrity, and availability when successfully exploited.
An attacker who already possesses arbitrary read and write primitives can leverage the race condition to bypass Pointer Authentication, potentially enabling further code execution or privilege escalation on the affected device. Exploitation requires network-adjacent access with low privileges and no user interaction, though the attack complexity is rated high.
Apple security advisories for the listed updates state that the issue is resolved by the patches released on or around 29 July 2024; administrators should apply iOS 17.6, iPadOS 17.6, macOS Sonoma 14.6, macOS Ventura 13.6.8, tvOS 17.6, and watchOS 10.6 (or later) to eliminate the race condition.
The associated EPSS score remains flat at 0.0715 with no material increase after disclosure, indicating limited observed exploitation interest to date.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Awareness training educates users on avoiding untrusted links and actions that can be exploited via CSRF.
Accurate timestamps from internal clocks enable detection of race conditions by providing reliable event ordering in audit logs.
Requiring user re-entry of credentials for sensitive actions prevents automated forgery of requests without active user participation.
Coordination of concurrent security activities reduces the probability that shared resources will be accessed simultaneously without proper synchronization.
Security testing regimens explicitly include checks for missing or ineffective anti-CSRF protections in web applications.
Detects anomalous request patterns consistent with cross-site request forgery.
