CVE-2025-50165

Exploitation: poc CVSS 9.8 CRITICAL

CVSS base score: 9.8 (Critical) vendor CNA · v3.1

Description

Untrusted pointer dereference in Microsoft Graphics Component allows an unauthorized attacker to execute code over a network.

Lifecycle Timeline

Each milestone comes from a different source, so gaps between them are gaps in what those sources publish, not evidence that nothing happened. EPSS history for this CVE holds 70 points from 2025-08-16, tracked daily from 2026-09-09; earlier points are weekly, which dates a spike to within a week. Peak probability 23.5% on 2026-06-13.

Research & News Coverage

DateSourceArticle
2025-12-22 ESET WeLiveSecurity Revisiting CVE-2025-50165: A critical flaw in Windows Imaging Component

Articles from monitored vendor research blogs and security news feeds that specifically mention this CVE. Coverage begins when feed monitoring started; earlier articles are not indexed.

Detection & Exploitation

Exploit / Pen Test
Network IDS/IPS
none published
Host / SIEM
none published

Coverage across public collections only: Nuclei and OpenVAS NVT (scan); Snort and Suricata ET Open (network); Sigma and YARA (host/SIEM); Metasploit, Exploit-DB and public GitHub repositories (exploit). Absence here means nothing public was found, not that detection is impossible.
GitHub PoC repositories are collected automatically by PoC-in-GitHub (CC0) and are not vetted: some are fakes and some are malware. Treat them as evidence that code was published, not as code to run.
OpenVAS coverage derives from the Greenbone Community Feed, made available under the Open Database License (ODbL) v1.0; its individual Vulnerability Tests are licensed GNU GPL v2.

CWE-822: Untrusted Pointer Dereference, CWE-908: Use of Uninitialized Resource

The vendor's own judgement about their own code, shown alongside CISA's rather than merged into it. The exploitability index is a forward-looking prediction, distinct from a CVSS severity or CISA's SSVC decision, and vendors often report observed exploitation before a CVE reaches the KEV catalog.
