A patch for 2.6 was committed:
http://lia64.bkbits.net:8080/linux-ia64-release-2.6.11/cset@41f2d1eePludGYyb1yOmGaW6Iois8Q

Impact looks like it is a unprivileged DoS at least, possibly more.

Currently embargoed, no date set.

Comment 3 Jim Paradis 2005-06-14 22:20:54 UTC 
This is not an issue on AS2.1/ia64 because the mechanisms described
(syscall_trace_enter/syscall_trace_leave) are not implemented there.  The only
calls to syscall_trace are through an assembly-language wrapper
(invoke_syscall_trace) that does the proper preservation of arg registers.
