      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmd/raid1: fix writes_pending and barrier reference leaks on write failures\n\nraid1_make_request() acquires a writes_pending reference with\nmd_write_start() before calling raid1_write_request(). Several failure\npaths in raid1_write_request() complete the bio and return without\nreaching the normal write completion path, causing the corresponding\nmd_write_end() to be skipped.\n\nMake raid1_write_request() return a status indicating whether the write\nrequest was successfully queued. This allows raid1_make_request() to\ncall md_write_end() when raid1_write_request() fails.\n\nAdditionally, if wait_blocked_rdev() fails after wait_barrier()\nsucceeds, the associated barrier reference is not released.\n\nCall allow_barrier() before returning from that path to keep the barrier\naccounting balanced.",
