CVE-2026-110261 · OW2 ASM 3.0 before 9.11 Excessive CPU Consumption via ClassWriter COMPUTE_FRAMES

This page contains facts from public vulnerability sources. Check the original advisory before updating.

OW2 ASM 3.0 before 9.11 contains a denial of service vulnerability that allows attackers to exhaust CPU by supplying crafted class files processed with ClassWriter.COMPUTE_FRAMES. Attackers can craft methods that make the unbounded MethodWriter.computeAllFrames() fix point algorithm converge slowly, tying up transforming threads for unbounded time.
