CVE-2026-115893
Wasmtime is a runtime for WebAssembly. Prior to 36.0.19, 48.0.7, and 49.0.4, the Cranelift compiler backend on aarch64 can compile a Wasm brtable instruction with more than approximately 256,000 targets so that it has an incorrect conditional branch target. The branch can then jump to arbitrary...

CVE-2026-115893
The Wasmtime WebAssembly runtime is vulnerable to a sandbox escape on aarch64 engines using the default Cranelift backend. The issue occurs when processing a br_table instruction containing more than approximately 256,000 targets, causing an incorrect conditional branch target . This allows a use...

capstone: Capstone: Denial of Service and parser desynchronization via WebAssembly `br_table` instruction-size truncation
A flaw was found in Capstone, a disassembly framework, affecting its WebAssembly WASM backend. A remote attacker could exploit this by providing a specially crafted brtable instruction. This could lead to a denial of service, where the disassembler gets stuck in a loop, or cause parser...

SUSE CVE-2026-49263
Capstone is a disassembly framework. Prior to version 6.0.0-Alpha9, Capstone's WebAssembly backend accepts attacker-controlled raw WASM instruction bytes through the public csdisasm and csdisasmiter APIs. For a large but well-formed brtable instruction, the WASM decoder accumulates the immediate...
Numeric Truncation Error
Overview Affected versions of this package are vulnerable to Numeric Truncation Error in readbrtable in arch/WASM/WASMDisassembler.c. An attacker can cause no-progress disassembly or parser desynchronization by supplying a large, well-formed brtable instruction through csdisasm or csdisasmiter. T...

CVE-2026-49263
Summary: CVE-2026-49263 affects Capstone’s WebAssembly backend prior to 6.0.0-Alpha9. The WASM decoder in cs_disasm() and cs_disasm_iter() can be fed attacker-controlled raw instruction bytes, and for large but well-formed br_table encodings it can mis-handle lengths (exactly 65,536), causing the...
