TITLE

plural NXP Kinetis Authentication vulnerabilities in product devices

Trust: 0.8

sources: JVNDB: JVNDB-2019-009672

DESCRIPTION

On NXP Kinetis KV1x, Kinetis KV3x, and Kinetis K8x devices, Flash Access Controls (FAC) (a software IP protection method for execute-only access) can be defeated by leveraging a load instruction inside the execute-only region to expose the protected code into a CPU register. NXP Kinetis KV1x , KV3x , K8x Devices have authentication vulnerabilities.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. NXP Semiconductors NXP Kinetis KV1x, etc. are all microcontrollers from NXP Semiconductors in the Netherlands. A security vulnerability exists in NXP Semiconductors NXP Kinetis KV1x, Kinetis KV3x, and Kinetis K8x. An attacker could exploit this vulnerability to bypass Flash Access Controls (FAC) protection
