CVE-2015-2291 — Intel Ethernet Diagnostics Driver for Windows Denial-of-Service Vulnerability

(1) IQVW32.sys before 1.3.1.0 and (2) IQVW64.sys before 1.3.1.0 in the Intel Ethernet diagnostics driver for Windows allows local users to cause a denial of service or possibly execute arbitrary code with kernel privileges via a crafted (a) 0x80862013, (b) 0x8086200B, (c) 0x8086200F, or (d) 0x80862007 IOCTL call.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

CISA KEV · Feb 10, 2023 R used by ransomware (CISA) ☠ Scattered Spider Exploit-DB · 1
How the score was calculated
  • Confirmed exploitation (CISA KEV)+35
  • Used in ransomware campaigns (CISA)+10
  • Exploited by 1 threat actor(s) (MITRE ATT&CK)+10
  • Public exploit/PoC (exploitdb)+8
  • EPSS 9% (30-day exploitation probability)+14
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Apply updates per vendor instructions.

US federal deadline: Mar 3, 2023 — passed 1322 day(s) ago

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Intel Ethernet Diagnostics Driver Iqvw32.sys, Intel Ethernet Diagnostics Driver Iqvw64.sys).
  2. Treat as emergency remediation: the CVE is in CISA KEV (confirmed exploitation).
  3. Apply the fixed version or the patch documented under Remediation.
  4. EPSS ahead of 95% of scored CVEs: prioritize it in the patch queue.
  5. Search available logs for exploit probes matching the vulnerability class (input validation), errors and authentication anomalies.

CISA KEV details CISA

CISA lists a CVE once it has evidence of exploitation against real targets.

Listed
Feb 10, 2023
Federal deadline
Mar 3, 2023
passed 1322 day(s) ago
Ransomware use
Known

CISA records ransomware use only for campaigns it has confirmed, so “Unknown” means unrecorded, not ruled out. The deadline binds US federal agencies; for everyone else it is a reference date.

Public exploits, PoCs and detection templates

Public code that demonstrates or tests the flaw raises the odds of mass exploitation — and Nuclei templates help find vulnerable assets in your environment.

Exploit-DB

Warning: public PoCs are sometimes disguised malware. Use them only for authorized testing in an isolated environment. This portal does not host exploit code — it only points to the sources.

What should defenders know first?

CVE-2015-2291 is "Intel Ethernet Diagnostics Driver for Windows Denial-of-Service Vulnerability", rated High. It affects Ethernet Diagnostics Driver Iqvw32.sys (Intel); versions are in the scope table. It is in CISA KEV: there is evidence of real-world exploitation. CVSS 7.8 describes technical severity. EPSS 9.01% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
