CVE-2026-80864

CVE-2026-80864 is a use-after-free in the Linux kernel's RDMA/rxe subsystem. The flaw occurs because rxe_qp_from_attr() handles IB_QP_MAX_DEST_RD_ATOMIC outside the IB_QP_STATE path, holding no state_lock and running concurrently with the live responder task rxe_receiver(). A modify_qp() call set...

CVE-2026-80863

CVE-2026-80863 is a slab out-of-bounds write (size 4) in the Linux kernel's RDMA/rxe (Soft-RoCE) driver, specifically in free_rd_atomic_resources() at drivers/infiniband/sw/rxe/rxe_qp.c. The root cause is that max_dest_rd_atomic is updated before the old array is freed, causing the free path to i...
