Description
Description
In the Linux kernel, the following vulnerability has been resolved:
pnfs/blocklayout: Fix device leaks on parse failure
bl_parse_concat() and bl_parse_stripe() allocate a child device array and
then parse each child in turn. If parsing a child fails, the failed child is
not counted in nr_children and the parent may be left with a children array
that bl_free_device() will not release when nr_children is zero.
Release the failed child and the already parsed children before returning the
error. Also make bl_free_device() release the child array whenever the
children pointer is set, so that partially initialised concat or stripe
devices are cleaned up correctly.
bl_parse_scsi() can also fail after assigning d->bdev_file and dropping the
file reference. Clear the pointer after fput() so that an outer cleanup path
does not put it again.
