Description Mark J. Cox 2007-09-20 14:12:21 UTC

The RHEL kernel was missing some stack unwinder fixes which leads to an
incorrect CS bit being set, and a kernel OOps.  This can be triggered by an
unprivileged local user on a EM64T architecture system.

Note this doesn't affect upstream which contains a different fix.

More details, fix, and reproducer in bz#213313

Marking private until update is released.
