Description
In the Linux kernel, the following vulnerability has been resolved: KEYS: trusted: Fix a memory leak in tpm2_load_cmd 'tpm2_load_cmd' allocates a tempoary blob indirectly via 'tpm2_key_decode' but it is not freed in the failure paths. Address this by wrapping the blob into with a cleanup helper.

Executive Summary

This vulnerability is a memory leak in the Linux kernel's KEYS trusted subsystem. Specifically, the function 'tpm2_load_cmd' allocates a temporary blob indirectly via 'tpm2_key_decode', but this allocated memory is not freed properly in failure paths, leading to a memory leak. The issue was fixed by wrapping the blob with a cleanup helper to ensure proper memory management.

Impact Analysis

The memory leak could lead to increased memory usage and potentially degrade system performance or stability over time if the failure paths are triggered repeatedly. This could affect systems relying on the Linux kernel's TPM2 key handling, possibly causing resource exhaustion.
