CVE-2026-53280
|
| Sažetak |
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. |
