CVE-2026-80863

A flaw was found in the Linux kernel's RDMA/rxe component. A local user could exploit a memory corruption vulnerability in the freerdatomicresources function by updating the maxdestrdatomic value before the old array is properly freed, leading to an out-of-bounds write. This issue can cause a...

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...
