  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nmd/raid10: fix leak of 'r10bio->remaining' for recovery\nraid10_sync_request() will add 'r10bio->remaining' for both rdev and\nreplacement rdev. However, if the read io fails, recovery_request_write()\nreturns without issuing the write io, in this case, end_sync_request()\nis only called once and 'remaining' is leaked, cause an io hang.\nFix the problem by decreasing 'remaining' according to if 'bio' and\n'repl_bio' is valid." ],
  "statement" : "RAID10 recovery could leak the r10bio->remaining counter on read failure, preventing completion and causing an I/O hang. The fix decrements the counter only for actually issued bios, avoiding the stall.\nThis is a reliability bug, not remotely triggerable: it requires a RAID10 in recovery and device read errors, typically under administrative control. Impact is limited to availability (local I/O DoS).",
