A client that connects to a malicious AFP server can cause a buffer overflow, corrupting kernel memory. This memory corruption could enable an attacker to execute arbitrary code with kernel privileges; based on the description, it is inferred that such an escalation is possible but not explicitly confirmed.", "risk_and_exploitability": "The CVSS score of 8.8 classifies the flaw as high\u2011severity. The EPSS score of less than 1\u202f% indicates that exploitation is currently unlikely. The vulnerability is not listed in the CISA KEV catalog. The attack vector requires a network connection to an AFP server, so remote access via AFP communications is the expected trigger."}}}}, "created": "2026-04-28T11:30:29.833803+00:00", "title": "Kernel Memory Corruption via AFP Server in macOS", "updated": "2026-04-28T11:30:29.833818+00:00", "vendors": []}
