Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the switch to function in the Linux kernel, which does not properly context-switch IOPL on 64-bit PV Xen guests. This allows local guest OS users to gain privileges, cause a denial of service (guest OS crash), or obtain sensitive information by leveraging I/O port access.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
