Security readout for executives and security teams
Plain-English summary
CVE-2022-3046 is a high-severity Google Chrome flaw fixed in version 105.0.5195.52. A successful attack required tricking a user into installing a malicious extension, then using crafted HTML to trigger memory corruption. The main business risk is compromised browser sessions and data exposure on outdated endpoints.
Executive priority
Treat as a high-priority browser patching issue, especially for workstations with sensitive access. It is not marked KEV in the provided bundle, but the impact rating and browser attack surface justify prompt remediation.
Technical view
The issue is a CWE-416 use-after-free in Chrome's Browser Tag component before 105.0.5195.52. The CVSS 3.1 score is 8.8, with network attack vector, low complexity, required user interaction, and high confidentiality, integrity, and availability impact.
Likely exposure
Organizations are mainly exposed where Chrome versions earlier than 105.0.5195.52 remain in use, especially on unmanaged endpoints or systems allowing users to install untrusted browser extensions.
Exploitation context
The bundle does not show CISA KEV inclusion or state active exploitation. The described attack path requires social engineering: persuading a user to install a malicious extension and interact with crafted HTML.
Researcher notes
Evidence is strongest for affected version range, weakness class, and required user interaction. Public details in the bundle are limited; do not infer broader Chromium-based product impact, active exploitation, or exploit availability beyond the cited records.
Mitigation direction
- Update Google Chrome to 105.0.5195.52 or later.
- Apply relevant Gentoo or Fedora browser package updates where applicable.
- Check current vendor guidance before relying on compensating controls.
- Restrict installation of unapproved Chrome extensions on managed devices.
- Prioritize remediation on endpoints used for privileged web access.
Validation and detection
- Inventory Chrome versions across managed and unmanaged endpoints.
- Confirm no Chrome installations remain below 105.0.5195.52.
- Review browser extension policy enforcement on managed devices.
- Check for unapproved or suspicious Chrome extensions.
- Verify applicable Linux distribution advisories are remediated.
