The vulnerability is classified as a confidentiality breach (CWE-200) and, if exploited, could enable privilege escalation or further exploitation of the operating system.", "risk_and_exploitability": "The CVSS score of 9.8 indicates critical severity, while the EPSS score of less than 1% suggests a small likelihood of immediate exploitation. The vulnerability is not listed in the CISA KEV catalog. Attackers would need to run a malicious application locally on the target machine; thus the attack vector is likely local. Given the high impact on confidentiality, the flaw warrants urgent attention."}}}}, "created": "2025-07-30T11:10:19.730859+00:00", "title": "Kernel Memory Disclosure via Improper Memory Handling in macOS", "updated": "2026-04-28T01:00:10.123053+00:00", "vendors": ["apple", "apple$PRODUCT$macos", "apple$PRODUCT$macos_sequoia", "apple$PRODUCT$macos_sonoma"]}
