CVE-2026-90150

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.
