Description Petr Matousek 2011-03-18 12:45:29 UTC
Description of the problem:
The user-supplied index into the adapters array needs to be checked, or
an out-of-bounds kernel pointer could be accessed and used, leading to
potentially exploitable memory corruption.

Comment 1 Petr Matousek 2011-03-18 12:48:07 UTC
Statement:

The Linux kernel as shipped with Red Hat Enterprise Linux 4, 5, 6 and
Red Hat Enterprise MRG are not affected as they did not backport upstream
commit 719f82d3 that introduced this issue.
