CVE-2015-8374 (retired)

Priority
Description
fs/btrfs/inode.c in the Linux kernel before 4.3.3 mishandles compressed
inline extents, which allows local users to obtain sensitive pre-truncation
information from a file via a clone action.
Ubuntu-Description
It was discovered that the Btrfs implementation in the Linux kernel
incorrectly handled compressed inline extants on truncation. A local
attacker could use this to expose sensitive information.
