CVE-2026-53280 is fixed in linux on 1 platform by DEBIAN-CVE-2026-53280 (version 7.0.10-1), released June 27, 2026. It is not reported as exploited. Patch Radar priority: Routine.
In the Linux kernel, the following vulnerability has been resolved: iommu: Fix NULL group->domain dereference in pci_dev_reset_iommu_done() Local sashiko review pointed it out that group->domain could be NULL when a default domain fails to allocate during the first probe, which can crash at domain->ops->attach_dev dereference in __iommu_attach_device() invoked by pci_dev_reset_iommu_done(). pci_dev_reset_iommu_prepare() is fine as an old_domain pointer can be NULL. Skip the re-attach in pci_dev_reset_iommu_done() to fix the bug.
