Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are affected are 8.0.29 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS 3.1 Base Score 4.9 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H).

Security readout for executives and security teams

Plain-English summary

This is a service reliability risk in MySQL, not a data theft issue based on the sources. Someone who already has high database privileges and network access could crash or hang affected MySQL servers, interrupting dependent applications.

Executive priority

Treat as a scheduled remediation item unless the affected database supports critical services or has broad privileged access paths. Business impact is downtime, not confirmed confidentiality loss.

Technical view

CVE-2022-21517 affects Oracle MySQL Server InnoDB in 8.0.29 and prior. A high-privileged attacker with network access over multiple protocols can cause a hang or frequently repeatable crash. CVSS 3.1 is 4.9, with availability impact only.

Likely exposure

Exposure is most likely where MySQL Server 8.0.29 or earlier remains deployed and reachable by high-privileged database users or services over the network.

Exploitation context

The provided sources describe easy exploitation but require high privileges. The CVE is not listed as CISA KEV, and the bundle does not provide evidence of active exploitation or public exploit use.

Researcher notes

Evidence is limited to advisory-level details. No CWE is provided. Scope appears unchanged, with network attack vector, low complexity, high privileges required, and availability impact only.

Mitigation direction

  • Identify Oracle MySQL Server instances running 8.0.29 or earlier.
  • Apply Oracle July 2022 CPU guidance or later vendor-supported updates.
  • Review Fedora or NetApp advisories if using their packaged or affected products.
  • Restrict network access to MySQL administration and high-privilege accounts.
  • Monitor affected databases for unexplained hangs, crashes, or restart loops.

Validation and detection

  • Inventory MySQL Server versions across production, staging, and managed images.
  • Confirm whether InnoDB-backed MySQL instances are 8.0.29 or earlier.
  • Check package provenance against Oracle, Fedora, or NetApp advisory coverage.
  • Verify privileged database accounts are limited to required hosts and services.
  • Review uptime and error logs for repeated crash or hang patterns.
