CVE-2007-6733 is a vulnerability of currently unknown severity. The nfs_lock function in fs/nfs/file.c in the Linux kernel 2.6.9 does not properly remove POSIX locks on files that are setgid without group-execute permission, which allows local users to cause a denial of service (BUG and system crash) by locking a file on an NFS filesystem and then changing this file's permissions, a related issue to CVE-2010-0727.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
