Description
In the Linux kernel, the following vulnerability has been resolved:
drivers:md:fix a potential use-after-free bug
In line 2884, "raid5_release_stripe(sh);" drops the reference to sh and
may cause sh to be released. However, sh is subsequently used in lines
2886 "if (sh->batch_head && sh != sh->batch_head)". This may result in an
use-after-free bug.
It can be fixed by moving "raid5_release_stripe(sh);" to the bottom of
the function.
