How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-0609, inspect your project dependencies for CefSharp.Common:

inspect dependencies for CefSharp.Common

Analyze the terminal output to locate any version of CefSharp.Common in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 98.1.210), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-416: Use After Free, where the product reuses or references memory after it has been freed. at some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. In CefSharp.Common, software state validation or input boundaries are circumvented during processing.
