Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue concerns a crash that occurs when surprise hot-unplugging a PCI device in the Linux kernel. This happens because during hot-unplug, the
iommu group set domain nofail() function fails to attach the default domain when the platform no longer recognizes the device, resulting in a NULL domain pointer and Use After Free (UAF). Implementing a blocking domain prevents this UAF by handling the already removed device. The crash is fixed, but a warning still occurs when attempting to change DMA ownership on a blocked device.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
