CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2024-40815 is a high-severity Race Condition (CWE-362) vulnerability in Apple Macos. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 37% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SC-23 (Session Authenticity) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Mitigating Controls (NIST 800-53 r5) AI
Access enforcement requires verifying that state-changing requests originate from the authenticated user rather than a forged cross-site source.
Protecting session authenticity prevents attackers from replaying or forging authenticated requests via the victim's browser.
Maintaining separate execution domains for each process structurally eliminates unintended concurrent access to the same shared resources.
Preventing unintended information transfer through shared system resources directly addresses the improper concurrent modification that defines a race condition.

Secure SDLC practices directly require proper synchronization primitives and concurrency testing that prevent race conditions.

Security testing can detect race conditions, but does not prevent them at design or coding time.
By denying access to phishing or malicious sites, the control lowers the likelihood that a user will be tricked into submitting a forged request that performs an unintended action on another site.
Secure SDLC mandates concurrency controls and synchronization primitives that directly prevent race conditions.
Application security requirements can specify thread-safety and locking rules, but do not prescribe implementation details.
Secure architecture principles require proper synchronization and resource isolation, addressing the root cause of CWE-362.
Secure coding standards explicitly forbid unsafe concurrent access patterns and mandate atomic operations or locks.
