Summary
In the Linux kernel, the following vulnerability has been resolved: KEYS: trusted: Fix tpm2_load_cmd() boundary check tpm2_load_cmd() does boundary checks against the ASN.1 size i.e., payload->blob_len. Address this by passing the decoded blob size to tpm2_load_cmd(), and use it for the boundary checks.
