About this tag
The rockchip gpio tag covers a reported Linux kernel vulnerability in the Rockchip GPIO driver. The featured discussion of CVE-2026-53226 examines how generic IRQ chip structures can leak during device removal and later contribute to use-after-free crashes in kernel power-management callbacks. It explains why driver teardown paths matter to the security perimeter of embedded Linux systems, while emphasizing that the issue is narrow and does not mean Rockchip boards are broadly unsafe. This archive is useful for readers tracking Rockchip platform security, GPIO driver behavior, kernel lifecycle handling, and risks associated with device removal and power-management code.
