CVE-2026-74374

CVE-2026-74374 affects the Linux kernel’s md/raid1 and md/raid10 code paths. The fix replaces error-path detection that relied on r1_bio or raid10’s read_slot with md_cloned_bio(), addressing cases where the error path is NULL or -1 after bio splitting/resubmission. The consequence previously cou...
