Discussion

Multiple Vendor AMD CPU Local FPU Information Disclosure Vulnerability

Multiple vendors' operating systems are prone to a local information-disclosure vulnerability. This issue is due to a flaw in the operating systems that fail to properly use AMD CPUs.

Local attackers may exploit this vulnerability to gain access to potentially sensitive information regarding other processes executing on affected computers. This may aid attackers in retrieving information regarding cryptographic keys or other sensitive information.

This issue affects Linux and FreeBSD operating systems that use generations 7 and 8 AMD CPUs.

Exploit / POC

Multiple Vendor AMD CPU Local FPU Information Disclosure Vulnerability

Currently we are not aware of any exploits for this issue. If you feel we are in error or if you are aware of more recent information, please mail us at: [email protected]

Solution / Fix

Multiple Vendor AMD CPU Local FPU Information Disclosure Vulnerability

Solution:
Linux has released version 2.6.16.9 of the Linux kernel to address this issue.
