fix error-path detection with md_cloned_bio()","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmd/raid1,raid10: fix error-path detection with md_cloned_bio()\n\nDetect the error path using md_cloned_bio() instead of relying\non r1_bio in raid1 or r10_bio->read_slot in raid10, which may be\nNULL or -1 after splitting and resubmitting a failed bio.\n\nAs a result, the error path may not be recognized and memory\nallocations can incorrectly use GFP_NOIO instead of\n(GFP_NOIO | __GFP_HIGH), which can lead to a deadlock under\nmemory pressure.","state":0,"publishedAt":"2026-08-15T05:58:53.659+00:00","modifiedAt":"2026-10-21T12:45:31.666+00:00","affected":[{"ecosystem":"Vendor
