CVE-2007-6733: Linux Kernel

Medium severity, CVSS 4.7. EPSS: 0.4% chance of exploitation in the next 30 days.

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.
