Senserva AI Opinion for CVE-2025-58730

Another Inbox COM Objects global memory Remote Code Execution bug, matching the 9.9 CVSS score and 6 percent EPSS estimate of its siblings, affects Windows 11 25H2 and Windows 10 1809. This release contains an unusually large cluster of nearly identical COM Objects RCE CVEs, all pointing to the same underlying memory-handling weakness across different code paths. No confirmed exploitation or ransomware use.

Do this: Patch this together with the other COM Objects RCE fixes in one coordinated update rather than treating each as separate work.
