Synopsis

The remote host is missing a macOS update that fixes multiple vulnerabilities

Description

The remote host is running a version of macOS / Mac OS X that is 26.x prior to 26.6. It is, therefore, affected by multiple vulnerabilities:

 - A use-after-free issue was addressed with improved memory management. This issue is fixed in Safari 26.6, iOS 26.6 and iPadOS 26.6, macOS Tahoe 26.6, visionOS 26.6, watchOS 26.6. Processing maliciously crafted web content may lead to an unexpected Safari crash. (CVE-2026-64783)

 - A memory initialization issue was addressed with improved memory handling. This issue is fixed in iOS 26.6 and iPadOS 26.6, macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6, tvOS 26.6, visionOS 26.6, watchOS 26.6. An app may be able to cause unexpected system termination. (CVE-2026-64775)

 - Double Free and possible RCE vulnerability in Apache HTTP Server with the HTTP/2 protocol. This issue affects Apache HTTP Server: 2.4.66. Users are recommended to upgrade to version 2.4.67, which fixes the issue. (CVE-2026-23918)

 - The issue was addressed with improved memory handling. This issue is fixed in macOS Sonoma 14.8.8, macOS Tahoe 26.6. A malicious app may be able to corrupt memory of a system process. (CVE-2026-28911)

Note that Nessus has not tested for these issues but has instead relied only on the operating system's self-reported version number.

Solution

Upgrade to macOS 26.6 or later.
