Description Mark J. Cox 2005-11-28 10:15:39 UTC 
CVE-2005-3857 lease DoS
        The time_out_leases function in locks.c for Linux kernel
        before 2.6.15 allows local users to cause a denial of service
        (kernel log message consumption) by causing a large number of
        broken leases, which is recorded to the log using the printk
        function.

fix (remove printk):

Listing as moderate, but may be updated to important based on kernel team
investigation.
