CVE-2024-58010

Kernel memory corruption via unchecked relocation count

Published Feb 27, 2025 · Updated Aug 5, 2026

Integer overflow in Linux kernel binfmt_flat allows local users to corrupt kernel memory via a crafted FLAT binary on 32-bit systems. The loader computes full_data by adding data_len to relocs multiplied by the machine-word size without first bounding the header-supplied relocation count. Executing the crafted binary with binfmt_flat enabled is required, and the wrapped size permits out-of-bounds access to kernel memory.
