Comment 1 Eugene Teo (Security Response) 2008-07-15 04:49:21 EDT
Description of problem:
There is a bug in set_tssldt_descriptor routine that when it is called, it will
use a size larger than (entries * LDT_ENTRY_SIZE - 1), resulting in an unintended
miscalculation of the ldt limits.

Version-Release number of selected component (if applicable):
It only affects 2.6.25-based kernel releases.

Additional info:
RHEL kernels are not affected by this. Filing this for Fedora kernels.
