Security readout for executives and security teams
Plain-English summary
CVE-2023-22311 is a local privilege-escalation issue in Intel Optane PMem 100 Series Management Software before 01.00.00.3547. An authenticated local user could potentially gain higher privileges. It is not remotely exploitable based on the provided CVSS vector, and no active exploitation evidence is provided.
Executive priority
Treat as a moderate-priority infrastructure hygiene issue. It is not described as remotely exploitable or actively exploited, but privilege escalation on systems handling persistent memory can increase impact after initial access.
Technical view
The issue is CWE-284 improper access control. CVSS 3.1 is 6.7 with AV:L, AC:H, PR:L, UI:R, S:U, and high confidentiality, integrity, and availability impact. Affected software is Intel Optane PMem 100 Series Management Software before 01.00.00.3547.
Likely exposure
Exposure is likely limited to systems running Intel Optane PMem 100 Series Management Software below 01.00.00.3547, especially servers or workstations using Optane persistent memory tooling. The attacker must already have authenticated local access, so internet-facing exposure is not indicated by the source bundle.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation. Exploitation requires local access, low privileges, user interaction, and high attack complexity, which lowers broad operational urgency but still matters on shared or sensitive hosts.
Researcher notes
Available evidence identifies product, version boundary, CWE class, and CVSS vector, but not technical root cause details or exploit primitives. Do not infer affected platforms beyond the named Intel Optane PMem 100 Series Management Software before 01.00.00.3547.
Mitigation direction
- Upgrade affected software to version 01.00.00.3547 or later.
- Review Intel advisory INTEL-SA-00948 for vendor-specific remediation guidance.
- Limit local interactive access to systems running affected PMem management software.
- Prioritize shared administrative systems and high-value servers using Optane persistent memory.
Validation and detection
- Inventory systems with Intel Optane PMem 100 Series Management Software installed.
- Confirm installed versions are 01.00.00.3547 or later.
- Check whether affected systems allow non-admin local authenticated users.
- Document exceptions and track them against Intel advisory guidance.

Improper Access Control
Improper Access Control represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
