Summary
fs/exec.c in the Linux kernel before 2.6.37 does not enable the OOM Killer to assess use of stack memory by arrays representing the (1) arguments and (2) environment, which allows local users to cause a denial of service (memory consumption) via a crafted exec system call, aka an "OOM dodging issue," a related issue to CVE-2010-3858.
