      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndm-era: fix shadowed superblock leak on take-snap failure\n\nmetadata_take_snap() bumps the live superblock refcount and then\ndm_tm_shadow_block() allocates a new block for the metadata snapshot.\nIf the subsequent dm_sm_inc_block() of writeset_tree_root or\nera_array_root fails, the function only unlocks the clone and\nreturns.  The newly allocated shadow block is never returned to the\nmetadata space map, so each failed take-snap permanently leaks one\nmetadata block.\n\nFree the clone with dm_sm_dec_block() on those error paths, matching\nthe final step of metadata_drop_snap().",
