Analysis

AI-generated

Technical impact

Maliciously crafted files can trigger an out‑of‑bounds read due to missing bounds checking, leading to process termination. The flaw corresponds to CWE‑125 and results in a denial‑of‑service condition for the affected application or system service.

Affected Systems

The vulnerability affects Apple macOS across all recent products, with the fix implemented in macOS Sequoia 15.6, macOS Sonoma 14.7.7, and macOS Ventura 13.7.7. Versions of macOS before these releases remain vulnerable.

Risk and Exploitability

This flaw has a CVSS score of 7.1 and an EPSS score of less than 1 %, indicating it is not highly likely to be exploited. It is not listed in the CISA KEV catalog. Exploitation requires a malicious file to be processed by a target system, so the attack vector is via local or remote file delivery. The impact is a denial of service through unexpected application or service termination.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update macOS to Sequoia 15.6, Sonoma 14.7.7, or Ventura 13.7.7 or later as released by Apple
