Alert meAnalysisAIv1 – Sep 15, 2026
A null pointer dereference in GNU Binutils 2.47 lets a locally-supplied malformed ELF object crash the toolchain when the linker or related BFD-consuming utilities reach the elf_x86_allocate_dynrelocs() dynamic-relocation allocator in bfd/elfxx-x86.c. Only availability is impacted — the fault aborts the affected utility and no memory corruption, information disclosure, or code execution has been demonstrated, which is consistent with the CVSS 4.0 base score of 1.9 (AV:L/PR:L, VA:L only). Publicly available exploit code exists in a GitHub proof-of-concept repository linked from the NVD record, but there is no indication of active exploitation or CISA KEV listing; upgrading to Binutils 2.48 resolves the issue.
