From this webpage screenshot, we can extract the following key information about the vulnerability: 1. Vulnerability Description: - Issue: On certain systems, when using pages larger than 4K, MMIO space may be exposed. - Cause: In some cases, there is an unused 4K region within the GPU's BAR space that can be mapped to MMIO space. However, when using pages larger than 4K, this may expose MMIO space of size . 2. Fix Details: - Code Modification: Changes were made to the function in the file . - Changes Made: - Added a condition check: if is 0 or is greater than 4096, return error code . - If is greater than 4096, return error code . 3. Scope of Fix: - File: - Line Numbers: From -1311,7 to +1311,7, and from -1969,6 to +1969,9. 4. Fix Contributors: - Author: Alex Deucher - Committer: Greg Kroah-Hartman 5. Fix Context: - Issue ID: d8e408a82704 - Reason for Fix: Resolved the issue . 6. Fix Status: - Status: Fixed and merged into upstream. This information indicates that the vulnerability, which exposed MMIO space on certain systems, has been resolved by modifying the code to prevent exposure of MMIO space when using pages larger than 4K.
