CVE-2021-34372
Quick assessment
Affected
NVIDIA NVIDIA Jetson TX2 series, TX2 NX, AGX Xavier series, Xavier NX
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Nvidia NVIDIA Jetson TX2和NVIDIA Jetson TX1都是美国英伟达（Nvidia）公司的一款嵌入式系统开发模块。 NVIDIA Jetson 存在输入验证错误漏洞，该漏洞源于Trusty（NVIDIA 为 Jetson 设备生产的可信操作系统）驱动程序在 NVIDIA OTE 协议消息解析代码中包含一个漏洞，即 malloc() 大小计算中的整数溢出导致堆上的缓冲区溢出。攻击者可利用该漏洞导致信息披露,特权升级,拒绝服务。
