Subject: [PATCH 02/83] mdadm: Fix double free
|
2022-11-15 06:54:39 +00:00
|
|
|
|
|
|
|
|
If there was a size mismatch after creation it would get fixed on grow
|
|
|
|
|
in imsm_fix_size_mismatch(), but due to double free "double free or corruption (fasttop)"
|
|
|
|
|
error occurs and grow cannot proceed.
