The remote Windows host is missing security update 5075899. It is, therefore, affected by multiple vulnerabilities

  - Protection mechanism failure in MSHTML Framework allows an unauthorized attacker to bypass a security     feature over a network. (CVE-2026-21513)

  - Access of resource using incompatible type ('type confusion') in Desktop Window Manager allows an     authorized attacker to elevate privileges locally. (CVE-2026-21519)

  - Heap-based buffer overflow in Windows Hyper-V allows an authorized attacker to execute code locally.
    (CVE-2026-21244, CVE-2026-21248)

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

The remote Windows host is missing security update 5075897. It is, therefore, affected by multiple vulnerabilities

  - A heap-based buffer overflow issue was discovered in libjpeg-turbo in h2v2_merged_upsample_internal()     function of jdmrgext.c file. The vulnerability can only be exploited with 12-bit data precision for which     the range of the sample data type exceeds the valid sample range, hence, an attacker could craft a 12-bit     lossless JPEG image that contains out-of-range 12-bit samples. An application attempting to decompress     such image using merged upsampling would lead to segmentation fault or buffer overflows, causing an     application to crash. (CVE-2023-2804)
