MetricsAV:L/AC:M/Au:N/C:N/I:N/A:C
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.
