Garmin Forerunner 235是瑞士佳明（Garmin）公司的一款电子腕表。 Garmin Forerunner 235 8.20之前版本存在安全漏洞，该漏洞源于ConnectIQ TVM 整数溢出。该漏洞允许攻击者将恶意的ConnectIQ应用程序上传到ConnectIQ存储。 当为NEWA指令分配数组时，ConnectIQ程序解释器无法检查溢出。 这是整个MAX32630地址空间内的受限读/写原语。 成功的利用将使ConnectIQ应用商店应用程序可以逃脱并在受限的应用程序执行环境之外执行

Vulnerability Description
Garmin Forerunner 235 before 8.20 is affected by: Array index error. The component is: ConnectIQ TVM. The attack vector is: To exploit the vulnerability, the attacker must upload a malicious ConnectIQ application to the ConnectIQ store. The ConnectIQ program interpreter fails to check the index provided when accessing the local variable in the LGETV and LPUTV instructions. This provides the ability to both read and write memory outside the bounds of the TVM context allocation. It can be leveraged to construct a use-after-free scenario, leading to a constrained read/write primitive across the entire MAX32630 address space. A successful exploit would allow a ConnectIQ app store application to escape and perform activities outside the restricted application execution environment.
