Security readout for executives and security teams
Plain-English summary
CVE-2022-3050 is a high-severity Chrome WebUI memory-safety flaw on Chrome OS before 105.0.5195.52. A remote attacker would need to lure a user into specific UI interactions, but successful exploitation could compromise confidentiality, integrity, and availability. There is no provided evidence of known active exploitation.
Executive priority
Treat as a high-priority browser update issue. It requires user interaction, but the impact is severe and browsers are exposed to untrusted content daily. Prioritize managed Chrome OS fleets and any lagging Chromium packages.
Technical view
The issue is a CWE-787 heap buffer overflow in Chrome WebUI. The CVSS 3.1 score is 8.8, with network attack vector, no privileges required, user interaction required, and high confidentiality, integrity, and availability impact. Sources describe potential heap corruption through crafted UI interactions.
Likely exposure
Organizations with Chrome OS or managed Chrome/Chromium deployments below version 105.0.5195.52 are the likely exposure group. The supplied affected-product data is broad and does not enumerate every platform or package build.
Exploitation context
The sources support remote exploitation potential, but only after convincing a user to perform specific UI interactions. The bundle does not include proof of exploitation in the wild, and KEV status is false.
Researcher notes
Evidence points to WebUI heap corruption, not a generic webpage-only flaw. The public bundle does not provide technical root-cause detail, exploit primitives, or reliable exploit status. Avoid assuming broader affected platforms beyond the cited Chrome OS and vendor package advisories.
Mitigation direction
- Update Chrome OS or Chrome/Chromium packages to vendor-fixed versions.
- Prioritize systems below 105.0.5195.52 where Chrome OS is present.
- Apply Fedora or Gentoo package updates where those distributions maintain Chromium packages.
- Check current Google and distribution vendor guidance for supported fixed versions.
- Use browser management policy to accelerate updates on managed endpoints.
Validation and detection
- Inventory Chrome OS, Chrome, and Chromium versions across endpoints.
- Confirm no managed devices remain below 105.0.5195.52.
- Review vulnerability scanner results against CVE-2022-3050.
- Validate distribution package advisories were applied on Fedora and Gentoo systems.
- Monitor vendor advisories for any later clarification on affected builds.
