CVE-2026-40527
Description
A flaw was found in radare2. A remote attacker can exploit this by crafting an ELF (Executable and Linkable Format) binary that embeds malicious commands within its DWARF (Debugging With Attributed Record Formats) parameter names. When radare2 analyzes such a binary, these embedded commands are executed due to unsanitized parameter interpolation, leading to arbitrary shell command execution.
