CVE-2026-110262 affecting package objectweb-asm 9.6-1

Published Oct 14, 2026 · corrected/updated Oct 17, 2026 · evidence confidence medium

OW2 ASM 3.1 before 9.11 contains an excessive memory allocation vulnerability in the asm-commons AdviceAdapter that allows attackers to exhaust memory by supplying crafted class files. Attackers can craft bytecode with many forward jump targets in constructors, causing unbounded stack copies in forwardJumpStackFrames and allocation of hundreds of megabytes, leading to denial of service.

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.
