Description
In the Linux kernel, the following vulnerability has been resolved: dm: verity-loadpin: Only trust verity targets with enforcement Verity targets can be configured to ignore corrupted data blocks. LoadPin must only trust verity targets that are configured to perform some kind of enforcement when data corruption is detected, like returning an error, restarting the system or triggering a panic.

Executive Summary

This vulnerability involves the Linux kernel's dm-verity feature, specifically the verity-loadpin component. Verity targets can be set to ignore corrupted data blocks, which is insecure. The fix ensures that LoadPin only trusts verity targets that enforce data integrity by reacting to corruption through error returns, system restarts, or panics. This prevents silent acceptance of corrupted data.

Impact Analysis

If exploited, this vulnerability could allow corrupted data blocks to be accepted silently by the system, potentially leading to data integrity issues, system instability, or security breaches due to undetected tampering or corruption.
