AI-analyzed exploit summary This repository provides a detailed technical analysis of CVE-2026-26399, a stack-based use-after-return vulnerability in legacy versions of Arduino_Core_STM32. It includes root cause analysis, affected components, and impact assessment.
Description
A stack-use-after-return issue exists in the Arduino_Core_STM32 library prior to version 1.7.0. The pwm_start() function allocates a TIM_HandleTypeDef structure on the stack and passes its address to HAL initialization routines, where it is stored in a global timer handle registry. After the function returns, interrupt service routines may dereference this dangling pointer, resulting in memory corruption.
