Senserva AI Opinion for KB5041770

KB5041770 is a companion August 2024 update for the same Windows 11 24H2 and Windows 10 1809 builds, but it exists to fix a single vulnerability, CVE-2024-38178, already listed in CISA's Known Exploited Vulnerabilities catalog. Its CVSS of 7.5 is lower than KB5041160's headline flaw, but the shared 39 percent EPSS score means attackers are actively working exploits at this exploitability level. Because it is scoped to one CVE, verify it deploys alongside, not instead of, the broader August rollup.

Do this: Confirm KB5041770 is applied in addition to KB5041160 on every affected 24H2 and 1809 machine, since it patches a separate actively exploited CVE.
