Insertion of sensitive information into log file in Windows Kernel allows an unauthorized attacker to disclose information locally.

The remote Windows host is missing security update 5073457. It is, therefore, affected by multiple vulnerabilities

  - Untrusted pointer dereference in Windows Cloud Files Mini Filter Driver allows an authorized attacker to     elevate privileges locally. (CVE-2026-20857)

  - An issue was discovered in Broadcom) LSI PCI-SV92EX Soft Modem Kernel Driver through 2.2.100.1 (aka     AGRSM64.sys). There is Local Privilege Escalation to SYSTEM via a Stack Overflow in RTLCopyMemory (IOCTL     0x1b2150). An attacker can exploit this to elevate privileges from a medium-integrity process to SYSTEM.
    This can also be used to bypass kernel-level protections such as AV or PPL, because exploit code runs with     high-integrity privileges and can be used in coordinated BYOVD (bring your own vulnerable driver)     ransomware campaigns. (CVE-2023-31096)

  - Windows Remote Procedure Call Interface Definition Language (IDL) Elevation of Privilege Vulnerability     (CVE-2026-20832)

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 5073723. It is, therefore, affected by multiple vulnerabilities

  - Windows Remote Procedure Call Interface Definition Language (IDL) Elevation of Privilege Vulnerability     (CVE-2026-20832)

  - A vulnerability exits in driver SmSerl64.sys in Motorola SM56 Modem WDM Driver v6.12.23.0, which allows     low-privileged users to mapping physical memory via specially crafted IOCTL requests . This can be     exploited for privilege escalation, code execution under high privileges, and information disclosure.
    These signed drivers can also be used to bypass the Microsoft driver-signing policy to deploy malicious     code. (CVE-2024-55414)
