About this tag
The irq domain teardown tag covers a focused Linux kernel security issue involving Rockchip GPIO drivers and generic IRQ chip cleanup. The tagged discussion examines CVE-2026-53226, in which IRQ-related structures may remain allocated during device removal and later cause use-after-free crashes when power-management callbacks run. This places driver teardown paths within the security perimeter for embedded Linux systems, even though the vulnerability is limited to a specific hardware driver and kernel workflow. Readers will find coverage of IRQ resource leaks, device removal behavior, kernel crash risks, and the importance of carefully handling low-level cleanup across embedded platforms.

    CVE-2026-53226 Rockchip GPIO Bug: IRQ Chip Leak, Use-After-Free Risk

    CVE-2026-53226 is a newly published Linux kernel vulnerability, added to NVD on June 25, 2026, in the Rockchip GPIO driver, where generic IRQ chip structures can leak during device removal and later trigger use-after-free crashes during kernel power-management callbacks. The bug is narrow, but...
