The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Wasmtime is a runtime for WebAssembly. Prior to 36.0.19 and 43.0.0, the Cranelift compiler backend bit- packs SSA value indices in a way that can silently...

DEBIAN-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...

DEBIAN-CVE-2026-115889

Wasmtime is a runtime for WebAssembly. Prior to 36.0.19 and 43.0.0, the Cranelift compiler backend bit-packs SSA value indices in a way that can silently overflow in release builds when compiling a sufficiently large or specially crafted Wasm function with many SSA values. The overflow can make...

CVE-2026-115892

Wasmtime is a runtime for WebAssembly. From 46.0.0 until 48.0.7 and 49.0.4, lowering a host-created component-model stream or future into a guest can omit a required payload-type check after the value passes through guest code and returns through StreamAny, FutureAny, Val::Stream, Val::Future, or...

Wasmtime: Panic lowering a host-created component model stream into a guest that expects a different payload type

Summary Wasmtime may panic when the host lowers a component model stream or future into a guest, if the host created that stream or future with one payload type and the guest expects a different one. This can happen when an embedder creates a stream or future, passes it through a guest, receives ...

GHSA-9PVW-HWFG-92H5 Wasmtime: Panic lowering a host-created component model stream into a guest that expects a different payload type

This can happen when an embedder creates a stream or future, passes it through a guest, receives ...

Wasmtime: Bit-packing in Cranelift compiler causes silent overflow and miscompilation

Summary In Wasmtime prior to v43, the Cranelift compiler backend bit-packs its SSA value indices in a way that can result in silent overflow in release builds, and result in incorrect value references in the IR resulting in arbitrary miscompilation. A very large Wasm function body, or one that is...

GHSA-897F-G5GM-FMXM Wasmtime: Bit-packing in Cranelift compiler causes silent overflow and miscompilation

Summary In Wasmtime prior to v43, the Cranelift compiler backend bit-packs its SSA value indices in a way that can result in silent overflow in release builds, and result in incorrect value references in the IR resulting in arbitrary miscompilation. A very large Wasm function body, or one that is...

CVE-2026-115892

A flaw was found in Wasmtime. A malicious WebAssembly guest can cause a Denial of Service DoS by triggering an unhandled host runtime panic. When handling asynchronous streams or futures exchanged between the host and guest, Wasmtime fails to properly validate payload data types upon their return...

CVE-2026-115893 Wasmtime: Cranelift backend on aarch64 can jump to incorrect target on large Wasm `br_table` instruction

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...
