Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 3.12.8
Description
The issue is related to the
restore fpu checking function in the Linux kernel, which does not properly clear pending exceptions before executing an EMMS instruction on AMD K7 and K8 platforms. This can be exploited by local users to cause a denial of service or potentially gain privileges through a crafted application.Recommendations
For Linux kernel versions prior to 3.12.8, update to version 3.12.8 or later to resolve the issue. As a temporary workaround, consider restricting access to the
restore fpu checking function to minimize the risk of exploitation.Exploitability
