CVE-2026-18220 Binutils: binutils: out-of-bounds write in bfd dlx elf backend relocation processing

An out-of-bounds write vulnerability was found in the BFD library's DLX ELF backend bfd/elf32-dlx.c in GNU binutils. The dlxrtypetohowto function maps ELF relocation types to internal howto structures but fails to perform adequate bounds checking on attacker-controlled relocation type values via...

CVE-2026-56390 Arbitrary Output Location Change in GNU Bison

GNU Bison improperly handles grammar‑defined output paths. Grammar directives such as %output and %header allow specifying file paths, which are accepted without restriction and override caller‑supplied output options. When processing attacker-supplied grammar, this behavior allows directing...
