CVE-2007-3732 Information

Description

In Linux 2.6 before 2.6.23 the TRACE_IRQS_ON function in iret_exc calls a C function without ensuring that the segments are set properly. The kernel’s fs needs to be restored before the call in TRACE_IRQS_ON and before enabling interrupts so that \current\ references work. Without this \current\ used in the window between iret_exc and the middle of error_code where fs is reset would crash.
