Wasmtime has host data leakage with 64-bit tables and Winch

Impact Wasmtime's Winch compiler contains a bug where a 64-bit table, part of the memory64 proposal of WebAssembly, incorrectly translated the table.size instruction. This bug could lead to disclosing data on the host's stack to WebAssembly guests. The host's stack can possibly contain sensitive...

CVE-2026-35186

Wasmtime is a runtime for WebAssembly. From 25.0.0 to before 36.0.7, 42.0.2, and 43.0.1, 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 i...

CVE-2026-34945

Wasmtime (Winch) vulnerability: a bug in the 64-bit memory64 table.size translation could disclose data from the host stack to WebAssembly guests. Affected builds range 25.0.0 through just before 36.0.7, 42.0.2, and 43.0.1. Root cause: return value of table.size was statically typed as 32‑bit ins...
