Mdadm throws buffer-overflow sometimes, it depends on the building environment.
It happens 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.

[ Impact ]
mdadm crashes sporadically with error *** buffer overflow detected *** at some invokations:
- mdadm --detail-pl
- mdadm -CR /dev/md0 -l1 -n2 /dev/nvme0n1 /dev/nvme1n1
*** buffer overflow detected ***: terminated
Aborted (core dumped)
[ Test Plan ]
- Install mdadm
- Have 2 disks to create a RAID devices
- Issue this command several times:
[ Where problems could occur ]
The fix is very small and basically it replaces the unsafe functions call
to sprintf by calling snprintf for Intel platforms (platform_intel.c)
I do not expect high regression risk.
[ Other Info ]
mdadm is built with FORTIFY_SOURCE=3 (as it is done in Ubuntu 24.04).
and it uses the unsafe function sprintf() that will cause the
buffer-overflow error
It is fixed in mdadm upstream:
