Uninitialized Memory Vulnerability in NXP S32G3 Reference Design Board
CVE-2025-68222
What is CVE-2025-68222?
An issue exists in the NXP S32G3 Reference Design Board related to uninitialized memory in the s32_pinctrl_desc structure. This inadequately initialized memory can lead to intermittent allocation errors and parsing failures in dependent drivers. Specifically, the malfunction affects the I2C adapter operations, resulting in warnings and errors during hardware probing. The problem can be addressed through proper initialization of the s32_pinctrl_desc structure using devm_kzalloc instead of devm_kmalloc, ensuring all fields are set to zero and preventing potential runtime issues.
