SUSE CVE-2026-34941

Wasmtime is a runtime for WebAssembly. Prior to 24.0.7, 36.0.7, 42.0.2, and 43.0.1, Wasmtime contains a vulnerability where when transcoding a UTF-16 string to the latin1+utf16 component-model encoding it would incorrectly validate the byte length of the input string when performing a bounds chec...

GHSA-F984-PCP8-V2P7 Wasmtime has improperly masked return value from `table.grow` with Winch compiler backend

Impact Wasmtime's Winch compiler backend contains a bug where translating the table.grow operator causes the result to be incorrectly typed. For 32-bit tables this means that the result of the operator, internally in Winch, is tagged as a 64-bit value instead of a 32-bit value. This invalid...

CVE-2026-34941

A flaw was found in Wasmtime, a runtime for WebAssembly. When transcoding a UTF-16 string to the latin1+utf16 component-model encoding, Wasmtime incorrectly validates the byte length of the input string, checking the number of code units instead of the actual byte length. This vulnerability can...

Wasmtime segfault or unused out-of-sandbox load with `f64x2.splat` operator on x86-64

On x86-64 platforms with SSE3 disabled Wasmtime's compilation of the f64x2.splat WebAssembly instruction with Cranelift may load 8 more bytes than is necessary. When signals-based-traps are disabled this can result in a uncaught segfault due to loading from unmapped guard pages. With guard pages...
