CVE-2025-39698

CVE-2025-39698 concerns the Linux kernel io_uring/futex cleanup: io_futex_data is allocated upfront and wired into io_kiocb.async_data, but the request flag REQ_F_ASYNC_DATA may not be set at that time. On failure, the futex handler frees the data but may not clear async_data, so the data and fla...
