CVE-2026-90831
MediumCVSS 5.3Summary
A vulnerability was detected in GNU Binutils 2.47 in the function _bfd_elf_strtab_delref of file bfd/elf-strtab.c, related to the ELF String Table. The manipulation results in memory corruption. The attack requires local access and the exploit is publicly available.
Risk Assessment
A local attacker can use the publicly known exploit to cause memory corruption, potentially leading to a crash or arbitrary code execution in the context of processing binary files. The project has not responded to the report, so a fix may not be available.
Recommendation
Limit processing of untrusted binaries by Binutils, monitor official releases, and apply the update as soon as a fix is available. Until then, consider sandboxing tools that use Binutils.
