CVE-2024-53127

System crashes and corruption via oversized IDMAC requests

Published Dec 4, 2024 · Updated Aug 5, 2026

Denial of service in affected Linux kernels allows local users to trigger panics through large SD-card I/O on DesignWare MMC systems. The dw_mmc driver raises max_req_size even with 4 KB pages, allowing oversized IDMAC requests to exhaust SWIOTLB buffers and corrupt transferred data. The condition requires a DesignWare MMC controller and local access to its mounted filesystem or block device; affected boards can also panic while booting from SD media.
