Doc Text:	A flaw was found in the Linux kernel's Tegra cryptography module. This vulnerability occurs when the system fails to properly return an ENOMEM error value if an input buffer allocation fails during cryptographic operations in the tegra_ccm_do_one_req function. An attacker could potentially exploit this by triggering memory allocation failures, leading to a denial of service (DoS) condition where the system becomes unresponsive or crashes.	Story Points:	---
