The flaw, classified as CWE\u2011787, allows a malformed file to corrupt memory, causing the target application to terminate unexpectedly. The primary consequence is a denial\u2011of\u2011service effect for the affected application, compromising availability rather than confidentiality or integrity.", "risk_and_exploitability": "The CVSS score of 5.5 indicates a moderate severity. The EPSS score of less than 1% suggests a low probability of exploitation at the current time, and the vulnerability is not listed in the CISA KEV catalog. Based on the description, the likely attack vector is a local or remote application that parses user\u2011supplied files; an attacker must supply a crafted file that triggers the out\u2011of\u2011bounds write, leading to application crash. No mention of remote code execution or privilege escalation is provided, so the risk remains confined to local denial of service for the apps that process the file."}}}}, "created": "2025-11-04T16:34:44.029683+00:00", "title": "Out\u2011of\u2011Bounds Write Leading to Unexpected App Termination in macOS File Parsing", "updated": "2026-04-28T10:30:29.023552+00:00", "vendors": ["apple", "apple$PRODUCT$macos", "apple$PRODUCT$macos_sequoia", "apple$PRODUCT$macos_sonoma"]}
