Descriptions

A memory leak in the ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c in the Linux kernel through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-128c66429247.

Una pérdida de memoria en la función ccp_run_sha_cmd() en el archivo drivers/crypto/ccp/ccp-ops.c en el kernel de Linux versiones hasta 5.3.9, permite a atacantes causar una denegación de servicio (consumo de memoria), también se conoce como CID-128c66429247.

A flaw was found in the AMD Cryptographic Co-processor driver in the Linux kernel. An attacker, able to send invalid SHA type commands, could cause the system to crash. The highest threat from this vulnerability is to system availability.
