        "text": "On April 24, 2018, researchers disclosed a vulnerability that takes advantage of a buffer overflow vulnerability in NVIDIA TX1 BootROM when Recovery Mode (RCM) is active. This vulnerability could allow an unprivileged, local attacker to bypass secure boot and execute unverified code on an affected system.\r\n\r\nThe vulnerability has been identified by CVE-2018-6242.\r\n\r\nTo exploit this vulnerability, an attacker must be able to physically access the device along with the affected processor\u2019s USB connection. This vulnerability cannot be exploited remotely, even if the device is connected to the Internet.\r\n\r\nCisco has identified all products that use the NVIDIA TX1 processor and has released software updates to address this vulnerability. The software update will permanently disable the ability to activate RCM. Should customers attempt to downgrade their software version, the ability to activate RCM will no longer be available.\r\n\r\n\r\nThere are no workarounds that address this vulnerability.\r\n\r\nThis advisory is available at the following link:\r\nhttps://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180620-nvidia-tx1-rom [\"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180620-nvidia-tx1-rom\"]",
