Description:
Tony Griffiths has reported a vulnerability in the Linux Kernel, which can be exploited malicious, local users to cause a DoS (Denial of Service).
The vulnerability is cause due to a memory corruption error in the "dentry_unused" list within the "prune_dcache()" function. This can be exploited to crash the kernel when running on SMP hardware by causing a race condition such that one or more tasks exit while another task is reading their /proc entries.
The vulnerability has been reported in versions 2.6.15 through 2.6.17. Other versions may also be affected.
