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

md/raid1,raid10: fix error-path detection with md_cloned_bio()

Detect the error path using md_cloned_bio() instead of relying

on r1_bio in raid1 or r10_bio->read_slot in raid10, which may be

NULL or -1 after splitting and resubmitting a failed bio.

As a result, the error path may not be recognized and memory

allocations can incorrectly use GFP_NOIO instead of

(GFP_NOIO | __GFP_HIGH), which can lead to a deadlock under

memory pressure. (NVD)
