AI Analysis

Impact

An out‑of‑bounds read due to missing bounds checking can be triggered by a local application, causing unexpected system termination. The vulnerability does not grant code execution or data disclosure, but can lead to a denial of service by crashing the operating system or its services.

Affected Systems

Apple macOS is affected; systems running versions prior to macOS Sequoia 15.6, macOS Sonoma 14.7.7, or macOS Ventura 13.7.7 are vulnerable. The fix is available in these and later releases.

Risk and Exploitability

The CVSS score of 3.3 reflects low severity, and the EPSS suggests a very low exploitation probability (less than 1%). The vulnerability is not listed in CISA KEV, and the attack vector is inferred to be local, requiring an application capable of causing the out‑of‑bounds read to be executed. There is no evidence of remote exploitation or privilege escalation.
