The vulnerability specifically impacted the system\u2019s ability to safely handle buffer boundaries, and once exploited, could cause the operating system to crash, interrupting user activity and potentially leading to data loss or service interruption. The weakness is classified as CWE\u2011120, which typically indicates untrusted input is written beyond an intended buffer limit.", "risk_and_exploitability": "The CVSS score of 5.5 suggests moderate severity. The EPSS score of less than 1% indicates exploitation is currently unlikely, and the vulnerability is not listed in the CISA KEV catalog. While the description does not specify how the attacker would gain a foothold, it is reasonable to infer that the attack vector involves a malicious or compromised application running with user privileges, rather than an external network-based exploit."}}}}, "created": "2025-09-17T10:05:21.703124+00:00", "title": "Buffer Overflow Causing Unexpected System Termination in macOS", "updated": "2026-04-28T00:00:18.110808+00:00", "vendors": ["apple", "apple$PRODUCT$macos", "apple$PRODUCT$macos_sequoia", "apple$PRODUCT$macos_sonoma", "apple$PRODUCT$macos_tahoe"]}
