CVE-2025-5914Public exploit

Code execution via RAR node-count overflow

Published Jun 9, 2025 · Updated Aug 25, 2026

Memory corruption in libarchive before 3.8.0 allows local users to execute code or crash applications via a crafted RAR archive. The RAR reader lets a node-count multiplication wrap to zero, passes zero to realloc, and later frees the same allocation again. Exploitation requires an application to process a RAR archive containing more than four billion nodes and over 103 GB of available memory.
