AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Network-delivered media parsing with no auth (PR:N), but a victim must process the crafted media, so UI:R rather than UI:N; full RCE gives C/I/A:H.

Out-of-bounds read in Windows Direct Show allows an unauthorized attacker to execute code over a network.
AnalysisAI
Remote code execution in the Microsoft Windows DirectShow media framework arises from an out-of-bounds memory condition (classed as heap overflow, CWE-122) that lets a remote attacker run arbitrary code when a victim system processes maliciously crafted media. It affects the DirectShow component across nearly all supported Windows client and server releases (Windows 10/11, Server 2012 through Server 2025). …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target system to process attacker-supplied media through the Windows DirectShow framework - i.e., a crafted media file or stream must be opened or ingested by a DirectShow-backed application or service. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The supplied CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, 9.8) rates this as critical unauthenticated network RCE with no user interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Microsoft security update for your specific Windows build; Patch available per vendor advisory (MSRC), with fixed builds including 10.0.26100.33438 (Server 2025 / Win11 24H2), 10.0.28000.2954 (Win11 26H1), 10.0.22631.7582 (Win11 23H2), 10.0.20348.5622 (Server 2022), 10.0.17763.9245 (1809/Server 2019), 10.0.19045.7725 (22H2), 10.0.14393.9512 (1607/Server 2016), 6.3.9600.23397 (Server 2012 R2) and 6.2.9200.26349 (Server 2012), per https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-69715. … Detailed patch versions, workarounds, and compensating controls in full report. |
