  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmd/raid10: fix leak of 'r10bio->remaining' for recovery\n\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.\n\nFix the problem by decreasing 'remaining' according to if 'bio' and\n'repl_bio' is valid.",
