CVE-2025-8225Public exploit

Local memory exhaustion via repeated DWARF allocations

Published Jul 27, 2025 · Updated Jul 28, 2025

Memory leak in GNU Binutils 2.44 DWARF handling allows local users to exhaust process memory by processing a crafted file. In process_debug_info in binutils/dwarf.c, a zero num_debug_info_entries value is treated as proof that debug_information is unallocated, so fuzzed input triggers repeated allocations instead of reusing the existing allocation. Low-privileged local access is required, and the bounded impact is availability loss from memory exhaustion rather than data disclosure or modification.
