In the Linux kernel, the following vulnerability has been resolved: md/raid10: fix leak of r10bio->remaining for recovery raid10_sync_request() will add r10bio->remaining for both rdev and replacement rdev. However, if the read io fails, recovery_request_write() returns without issuing the write io, in this case, end_sync_request() is only called once and remaining is leaked, cause an io hang. Fix the problem by decreasing remaining according to if bio and repl_bio is valid.
