Intel and AMD disclosed about 132 vulnerabilities combined in their November 2023 security updates: SecurityWeek reported about 105 across 31 Intel advisories and 27 across five AMD advisories. This is a historical disclosure roundup published on November 15, 2023—not a new patch release in 2026. The total spans many products and does not mean every Intel or AMD customer was affected.

What the “over 130” figure counts

SecurityWeek’s November 15, 2023 report combined its reported counts for the two chipmakers: about 105 Intel vulnerabilities and 27 AMD vulnerabilities. The Intel figure is qualified as approximate in the report. The totals refer to issues covered by multiple advisories, not to 132 flaws in one processor or one product. They are the outlet’s reported figures, not a separately verified vendor-wide total. Read SecurityWeek’s report.

Intel vulnerabilities highlighted in the report

Reptar: a virtualized-host risk

Reptar (CVE-2023-23583) is a processor flaw that SecurityWeek said Intel discovered internally, with Google researchers also finding it independently. In the reported scenario, an attacker with access to a guest machine in a multi-tenant virtualized environment could crash the host and other guests running on it. Information disclosure or privilege escalation were described as possible impacts, not as confirmed exploitation. SecurityWeek’s account of Reptar.

Data Center Manager: a separate software issue

Data Center Manager (CVE-2023-31273) is distinct from Reptar: SecurityWeek described it as a software vulnerability with a reported CVSS score of 10 that could allow an unauthenticated attacker with network access to escalate privileges. The report is not a substitute for the vendor advisory’s authoritative severity details or affected-version list. SecurityWeek’s report.

Other Intel products mentioned

The report also identified high-severity flaws affecting Intel oneAPI, Server Board and Server System BIOS firmware, QuickAssist Technology, NUC software, One Boot Flash Update, Connectivity Performance Suite, In-Band Manageability, and Unison. It characterized the remaining reported advisories as medium or low severity. This list does not establish that every product version was affected.

AMD vulnerabilities highlighted in the report

CacheWarp and Secure Encrypted Virtualization

CacheWarp (CVE-2023-20592) affects AMD Secure Encrypted Virtualization (SEV), a technology used to protect virtual machines. SecurityWeek described potential consequences including control-flow hijacking, breaking into an encrypted VM, and privilege escalation. Those are potential risks described in the report, not evidence of widespread exploitation. SecurityWeek’s account of CacheWarp.

Other AMD components

AMD’s five reported advisories covered vulnerabilities in its Secure Processor (ASP), System Management Unit (SMU), SEV, SMM Supervisor, server components, and graphics drivers. SecurityWeek noted several high-severity issues with potential for arbitrary code execution or privilege escalation. It also reported four medium-severity graphics-driver flaws that could permit code execution or denial of service. These findings have different affected components and possible impacts; they should not be treated as one uniform risk.

How to check whether your system needs an update

  1. Identify the exact component and version. Record your processor or product model and, where relevant, the software or firmware version. A headline total alone cannot tell you whether your particular system is affected.
  2. Check the relevant vendor advisory. Use Intel or AMD’s current security-support information to match your specific product and version against the affected list and mitigation guidance. The November 2023 roundup does not provide complete version-by-version remediation tables or update numbers.
  3. Check the system manufacturer’s update channel. For a PC or server, consult its manufacturer for applicable BIOS or firmware updates and installation instructions. Follow the guidance for your precise model.
  4. Apply the applicable mitigation and verify the result. Install only an update identified for your product, following the vendor or manufacturer’s instructions. Do not infer that a system is still vulnerable—or that it is fixed—from the roundup alone.

For Reptar, the reported attack setting involved access to a guest in a multi-tenant virtualized environment; Data Center Manager was a separate, network-accessible software issue. CacheWarp concerned AMD SEV and potential virtual-machine risk. These distinctions matter when administrators assess exposure and prioritize the applicable vendor guidance.
