Title: Texas Instrument TI-RTOS输入验证错误漏洞（CNVD-2021-36201）

Description:

Texas Instruments TI-RTOS-MCU是美国Texas Instruments公司的一个应用系统。用于微控制器 (MCU) 的实时操作系统 (RTOS)。

Texas Instrument TI-RTOS 存在输入验证错误漏洞，该漏洞源于当配置为使用HeapMem堆(默认)时，malloc返回一个有效的指针，指向一个非常大的值上的一个小缓冲区，这可能会触发HeapMem alloc未保护的整数溢出漏洞，并导致代码执行。目前没有详细的漏洞细节提供。
