CVE-2026-91782
LowCVSS 3.3Summary
A vulnerability was detected in GNU Binutils 2.47 in the function elf_x86_allocate_dynrelocs in bfd/elfxx-x86.c, leading to a null pointer dereference. The attack requires local access, and the exploit is public.
Risk Assessment
A local attacker can cause a program crash (denial of service) or potentially exploit the bug for other purposes if the application uses binutils to process untrusted files.
Recommendation
Upgrade GNU Binutils to version 2.48 or later, which includes the fix.
