CVE-2022-49745

Local denial of service via probe rollback leak

Published Mar 27, 2025 · Updated May 11, 2026

Resource leak in Linux kernel 6.0 through 6.1.10 and 6.2-rc1 through 6.2-rc6 allows local users to exhaust resources via failed FPGA probes. An allocation-error path in m10bmc_sec_probe returns without erasing its fw_upload_xa identifier, leaving kernel resources retained after an unsuccessful probe. The path is limited to systems using the Intel MAX 10 BMC secure-update driver, and exploitation requires local low-privileged access.
