4 | Subject: path_openat(): fix double fput() | ||
5 | |||
6 | path_openat() jumps to the wrong place after do_tmpfile() - it has | ||
7 | already done path_cleanup() (as part of path_lookupat() called by | ||
8 | do_tmpfile()), so doing that again can lead to double fput(). | ||
9 | |||
10 | Fixes CVE-2015-5706. | ||
