Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.6.58

Description: A potential lockup issue has been identified in the Linux kernel, specifically in the iommu/vt-d component, when the qi submit sync() function is called with a count of 0. This issue has been resolved in upstream kernel version 6.6.58. The kmod-virtualbox and kmod-xtables-addons packages have been updated to work with this new kernel.

Recommendations: For versions prior to 6.6.58, update to version 6.6.58 or later to resolve the issue. As a temporary workaround, consider avoiding the use of the qi submit sync() function with a count of 0 until a patch is available.
