Candidate: CVE-2006-4814 References: http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2f77d107050abc14bc393b34bdb7b91cf670c250 Description: The mincore function in the Linux kernel before 2.4.33.6 does not properly lock access to user space, which has unspecified impact and attack vectors, possibly related to a deadlock.
