| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The issue is related to a NULL pointer dereference in the Linux kernel, specifically in the iommu/vt-d component. This occurs when the IOMMU operates in deferred attach mode and the
info->domain may not be assigned by the time the release device function is called, leading to a crash in the crash kernel. The scalable mode context entry not part of the release domain should be cleared in release device() to fix the issue. The vulnerability can be exploited to cause a denial of service.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
