{"schema":"threatline.record/2","record":{"id":"CVE-2026-98071","aliases":[],"summary":"net/rds: clear cp_flags bits individually in rds_conn_path_reset()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/rds: clear cp_flags bits individually in rds_conn_path_reset()\n\nrds_conn_path_reset() wipes the whole flag word with a plain\ncp->cp_flags = 0 store.  Every other accessor of that word uses\natomic bitops, and some of them can run concurrently with the reset:\nRDS_LL_SEND_FULL is set from rds_send_xmit() and cleared from the\ntransport completion paths, neither of which holds anything that\nexcludes the shutdown worker.  A plain store racing an atomic\nread-modify-write on the same word is a data race, and whichever\nside loses has its update silently discarded.\n\nClear the two bits the reset is actually responsible for instead.\nRDS_IN_XMIT and RDS_RECV_REFILL need no store at all here: they\nbelong to the caller, rds_conn_shutdown(), which waits for both to be\nclear before calling the transport shutdown and this reset.\n\nThis also gives every bit in cp_flags a single well-defined writer\ndiscipline, which the following patches rely on when they turn\nRDS_IN_XMIT and RDS_RECV_REFILL into bit locks held across the\nteardown: a blanket store mid-teardown would destroy lock ownership\nthat an atomic clear preserves.\n\nOracle UEK carries the same conversion (\"net/rds: Preserve essential\nconnection state flags\"), motivated by its asynchronous shutdown\nstate machine, whose progress and destroy flags must survive the\nreset.  UEK's variant also clears RDS_IN_XMIT and RDS_RECV_REFILL\nbecause there the reset runs as the final step of a teardown that\nowns both bits, making those clears its unlock.  Upstream that\nrelease belongs in rds_conn_shutdown(): once a later patch in this\nseries turns the two bits into locks held across the teardown, ending\nownership needs release semantics and a wake-up that a plain clear\ninside the reset would not provide.\n\nBased on Oracle UEK commit \"net/rds: Preserve essential connection\nstate flags\" by Gerd Rausch.","categories":["Operating
