The issue was addressed with improved memory handling. This issue is fixed in iOS 26.7 and iPadOS 26.7, iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Tahoe 26.7, tvOS 27, visionOS 27, watchOS 27. Connecting to a malicious NFS server may disclose kernel memory.

The remote host is running a version of macOS / Mac OS X that is 26.x prior to 26.7. It is, therefore, affected by multiple vulnerabilities:

  - A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and     unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI     library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a     maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the     application, possibly resulting in a denial of service (DoS) attack. (CVE-2022-3437)

  - A use after free issue was addressed with improved memory management. This issue is fixed in iOS 18.7.9     and iPadOS 18.7.9, iOS 26.5 and iPadOS 26.5, macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.5,     tvOS 26.5, visionOS 26.5, watchOS 26.5. An app may be able to cause unexpected system termination.
    (CVE-2026-28969)

  - An injection issue was addressed with improved validation. This issue is fixed in macOS Sequoia 15.7.8,     macOS Sonoma 14.8.8. An app may be able to gain root privileges. (CVE-2026-43698)

  - A race condition was addressed with improved state handling. This issue is fixed in iOS 26.5.2 and iPadOS     26.5.2, macOS Tahoe 26.5.2, tvOS 26.6, watchOS 26.6. An app may be able to cause unexpected system     termination. (CVE-2026-43743)

  - An access issue was addressed with improved access restrictions. This issue is fixed in macOS Sonoma     14.8.8, macOS Tahoe 26.6. An app may be able to access user-sensitive data. (CVE-2026-43760)

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

The version of Apple iOS running on the mobile device is prior to 27. It is, therefore, affected by multiple vulnerabilities.

The version of Apple iOS running on the mobile device is prior to 26.7. It is, therefore, affected by multiple vulnerabilities.
