CVE-2024-35829

Kernel memory exhaustion via failed Lima mappings

Published May 17, 2024 · Updated May 11, 2026

Memory leak in the Lima DRM heap allocator in Linux 5.7 and later affected branches allows local users to exhaust kernel memory. On a lima_vm_map_bo failure, lima_heap_alloc returns without unmapping the DMA scatter-gather table or freeing the table and its stored pointer. Low-privileged access to the Lima DRM interface is required, and repeated failed mappings can interrupt service through unreclaimed memory.
