Title:
  [VROC] [Ub 24.04] mdadm: buffer overflow detected

Status in mdadm package in Ubuntu:
  New

Bug description:
  Mdadm throws buffer-overflow sometimes, it depends on the building environment.
  It happens when mdadm is built with FORFTIFY_SOURCE=3 (as it is done in Ubuntu 24.04).

  Buffer-overflow is detected for many commands in this case:
  - mdadm --detail-pl
  - mdadm -CR /dev/md0 -l1 -n2 /dev/nvme0n1 /dev/nvme1n1
  *** buffer overflow detected ***: terminated
  Aborted (core dumped)

  It is fixed in mdadm upstream - please apply this patch to mdadm package and rebuilt it.
