Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to pointer dereference errors in the Linux kernel. It allows an attacker to access confidential data, compromise its integrity, and cause a denial of service. Specifically, with shadow paging enabled, the INVPCID instruction results in a call to
kvm mmu invpcid gva. If INVPCID is executed with CR0.PG=0, the invlpg callback is not set, leading to a NULL pointer dereference.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
