CVE-2026-110260

OW2 ASM 3.0 before 9.11 contains a quadratic memory allocation vulnerability in MethodWriter.computeMaxStackAndLocal() and computeAllFrames() when using COMPUTE_MAXS or COMPUTE_FRAMES. Attackers can supply a crafted class file with thousands of overlapping exception handlers, causing excessive Edge allocations and an OutOfMemoryError that crashes the JVM.
