Return ENOMEM Error in Tegra CCM Crypto Driver Buffer Allocation

Executive Summary

This vulnerability is in the Linux kernel's crypto subsystem, specifically in the Tegra cryptographic module. When processing a cryptographic operation, the function tegra_ccm_do_one_req fails to allocate an input buffer but does not properly set the ENOMEM error value, which indicates an out-of-memory condition.
