Linux Distros Unpatched Vulnerability : CVE-2022-48724

medium Nessus Plugin ID 225281

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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.
 (CVE-2022-48724)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
