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.
