CVE-2026-53226
5.5 · MEDIUMOverview
CVE-2026-53226 is a medium-severity vulnerability affecting linux linux_kernel. It was published on June 25, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
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
irq_alloc_domain_generic_chips() 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
IRQ_DOMAIN_FLAG_DESTROY_GC.
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
irq_domain_remove_generic_chips() before removing the IRQ domain in
rockchip_gpio_remove().
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
