From this webpage screenshot, we can extract the following key information about the vulnerability: 1. Vulnerability Description: - Title: tpm: Clean up TPM space after command failure - Description: The function does not roll back the TPM space after preparing it if the command fails. This could lead to transient handles being leaked if the device is powered off without further commands. 2. Fix Measures: - Fix Method: Resolved by clearing the TPM space in case of command transmission failure. - Fixed Code: Modifications were made in the files and . 3. Fix History: - Upstream Commit: - Fix Commit: 4. Fix Contributors: - Author: Jonathan McDowell - Committer: Greg Kroah-Hartman - Reviewer: Jarkko Sakkinen - Signer: Sasha Levin 5. Code Changes: - Files: and - Change Type: Added code to clean up TPM space. 6. Patch Status: - Status: Fixed, with code changes applied to both files. This information indicates that the vulnerability arises from the failure to roll back the TPM space after command preparation, potentially leaking transient handles if the device is powered off without further commands. The fix involves clearing the TPM space upon command transmission failure. The contributors have modified the relevant code, and the fix has been confirmed via upstream and downstream commits.
