Vulnerability from nvd – Published: 2026-10-14 14:16 – Updated: 2026-10-14 16:10

Title

OW2 ASM 3.0 before 9.11 Excessive Memory Allocation via Multiple RET Instructions

Summary

OW2 ASM 3.0 before 9.11 contains an excessive memory allocation vulnerability in Label.addSubroutineRetSuccessors() that fails to enforce the single-RET-per-JSR rule. Attackers can supply a crafted invalid class file with multiple RET instructions for one JSR, triggering a roughly 2 GB allocation that crashes the JVM.

CVE-2026-110257 (GCVE-0-2026-110257)

Vulnerability from nvd – Published: 2026-10-14 14:16 – Updated: 2026-10-14 15:55

Title

OW2 ASM 5.0 before 9.11 Excessive Memory Allocation via BootstrapMethods Attribute

Summary

OW2 ASM 5.0 before 9.11 contains an excessive memory allocation vulnerability in ClassReader.readBootstrapMethodsAttribute() that sizes an int array from num_bootstrap_methods without validating attribute_length. Attackers can supply a crafted class file of about 100 bytes that forces roughly 2 GB allocation, causing an OutOfMemoryError that crashes the JVM or consuming thread.

CVE-2026-110263 (GCVE-0-2026-110263)

Vulnerability from cvelistv5 – Published: 2026-10-14 14:16 – Updated: 2026-10-14 16:12

Title

OW2 ASM 3.0 before 9.11 Uncontrolled Recursion in SignatureReader

Summary

OW2 ASM 3.0 before 9.11 contains an uncontrolled recursion vulnerability in SignatureReader.parseType() that allows attackers to exhaust the stack via deeply nested generic type signatures. Attackers can supply a crafted class file with a long Signature attribute containing many nested type arguments to trigger a StackOverflowError during class transformation, causing denial of service.

Title

OW2 ASM 3.0 before 9.11 Uncontrolled Recursion via ClassWriter.replaceAsmInstructions()

Summary

OW2 ASM 3.0 before 9.11 contains an uncontrolled recursion vulnerability in ClassWriter.replaceAsmInstructions() that allows attackers to cause denial of service through crafted class files. Attackers can supply a class with a large method containing many long forward jumps, triggering unbounded toByteArray() recursion and a StackOverflowError during transformation.

Vulnerability from cvelistv5 – Published: 2026-10-14 14:16 – Updated: 2026-10-14 15:55

Title

OW2 ASM 5.0 before 9.11 Excessive Memory Allocation via BootstrapMethods Attribute

Summary

OW2 ASM 5.0 before 9.11 contains an excessive memory allocation vulnerability in ClassReader.readBootstrapMethodsAttribute() that sizes an int array from num_bootstrap_methods without validating attribute_length. Attackers can supply a crafted class file of about 100 bytes that forces roughly 2 GB allocation, causing an OutOfMemoryError that crashes the JVM or consuming thread.
