Summary

CVE-2022-41073 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Microsoft Windows 8.1. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 18% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2022-41073 is an elevation of privilege vulnerability in the Windows Print Spooler component, assigned CWE-787 for an out-of-bounds write condition. It affects supported Windows versions and carries a CVSS 3.1 base score of 7.8 reflecting local attack vector, low attack complexity, and low required privileges.

A local attacker with a valid low-privileged account can exploit the flaw to obtain SYSTEM-level privileges on the affected host. The vulnerability is triggered without user interaction once the attacker has access to the Print Spooler service.

Microsoft’s security update guide recommends installing the patches released in the November 2022 Patch Tuesday cycle; the same advisory is referenced by CISA’s Known Exploited Vulnerabilities catalog, confirming that the issue has been observed in active exploitation. The associated EPSS score remains low, with a recorded peak of 0.0328.
