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

md/raid10: fix writes_pending leak on write request failures

raid10_make_request() acquires a writes_pending reference with
md_write_start() before dispatching write requests. Several failure
paths in raid10_write_request() complete the bio and return without
reaching the normal write completion path, causing the corresponding
md_write_end() to be skipped.

Make raid10_write_request() return a status indicating whether the write
request was successfully queued. This allows raid10_make_request() to
release the writes_pending reference with md_write_end() when a write
request fails.
