Summary

In the Linux kernel, the following vulnerability has been resolved:

dm_early_create: fix freeing used table on dm_resume failure

If dm_resume fails, the kernel attempts to free table with dm_table_destroy, but the table was already instantiated with dm_swap_table. This commit skips the call to dm_table_destroy in this case.
