CVE-2010-1636
kernel: The btrfs_ioctl_clone function in fs/btrfs/ioctl.c ...
http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2010-1636

Original

The btrfs_ioctl_clone function in fs/btrfs/ioctl.c in the btrfs functionality in the Linux kernel 2.6.29 through 2.6.32, and possibly other versions, does not ensure that a cloned file descriptor has been opened for reading, which allows local users to read sensitive information from a write-only file descriptor.
