Summary
CVE-2026-53226 affecting package kernel 6.6.150.1-1
Details

In the Linux kernel, the following vulnerability has been resolved:

gpio: rockchip: fix generic IRQ chip leak on remove

The driver allocates domain generic chips using irqallocdomaingenericchips() during probe. However, on driver remove/teardown, the generic chips are not automatically freed when the IRQ domain is removed because the domain flags do not include IRQDOMAINFLAGDESTROYGC.

This causes both the domain generic chips structure and the associated generic chips to be leaked. Additionally, the generic chips remain on the global gc_list and may later be visited by generic IRQ chip suspend, resume, or shutdown callbacks after the GPIO bank has been removed, potentially resulting in a use-after-free and kernel crash.

Fix the resource leak by explicitly calling irqdomainremovegenericchips() before removing the IRQ domain in rockchipgpioremove().
