      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nmd/raid1: free r1_bio when REQ_NOWAIT is set and read would block on retry\n\nWhen a read is retried, raid1_read_request() may be called with a\npre-allocated r1_bio. If wait_read_barrier() fails for a REQ_NOWAIT\nread, the bio is completed and the function returns immediately. In this\ncase the existing r1_bio is leaked.\n\nThis fixes a leak of pre-allocated r1_bio structures for retried reads.",
