Ubuntu.comUB:CVE-2022-48724CVE-2022-48724
In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Fix potential memory leak in intel_setup_irq_remapping() After
commit e3beca48a45b (“irqdomain/treewide: Keep firmware node
unconditionally allocated”). For tear down scenario, fn is only freed after
fail to allocate ir_domain, though it also should be freed in case
dmar_enable_qi returns error. Besides free fn, irq_domain and ir_msi_domain
need to be removed as well if intel_setup_irq_remapping fails to enable
queued invalidation. Improve the rewinding path by add out_free_ir_domain
and out_free_fwnode lables per Baolu’s suggestion.
