Undefined behavior via unchecked analysis-length multiplication
Published Jul 5, 2026 · Updated Jul 5, 2026
Integer overflow in radare2 6.1.0 through 6.1.6 allows local users to trigger undefined behavior through the aos command. The core_anal_bytes path multiplies the command-supplied analysis length by eight in a signed int without first checking whether the result is representable. Local users must already be able to run radare2 commands; public evidence demonstrates sanitizer-detected undefined behavior but not code execution or a normal-build crash.
