Description Eugene Teo (Security Response) 2009-04-22 03:26:41 UTC 
Description of problem:
AGP pages might be mapped into userspace finally, so the pages should be set to zero before userspace can use it. Otherwise there is potential information leakage.

This fix for this was added to 2.6.29.3 and MRG-1.2 is based on 2.6.29.4 so this should not be an issue for MRG-1.2
