According to isec.pl on Nov19: "There is a subtle race condition finally permitting a non-root user to increment (up to 256 times) any arbitrary location(s) in kernel space. The condition is not easy to exploit since an attacker must trick kmalloc() to sleep on allocation of a special chunk of memory and then convince the scheduler to execute another thread. But it is feasible." http://linux.bkbits.net:8080/linux-2.4/cset@4199284dnTPrPLR-yhP_rOBHXJlltA Therefore fixed in 2.4.28 http://linux.bkbits.net:8080/linux-2.6/cset@419927f5Wy2IOKwcqE2S3DTNYSmCqQ Therefore will be fixed in 2.6.10 CVE name applied for
