CVE-2026-34971
Wasmtime is a runtime for WebAssembly. From 32.0.0 to before 36.0.7, 42.0.2, and 43.0.1, Wasmtime's Cranelift compilation backend contains a bug on aarch64 when performing a certain shape of heap accesses which means that the wrong address is accessed. When combined with explicit bounds checks a...
CVE-2026-34971
Wasmtime’s Cranelift backend on the aarch64 path contains a miscompile of a specific load pattern (load(iadd(base, ishl(index, amt)))) that can diverge between bounds checking and loading, enabling an arbitrary read/write of host memory and thus a sandbox escape for guest WebAssembly. Affected ra...

CVE-2026-27887 Spin has memory leaks in various WIT interfaces
Spin is an open source developer tool for building and running serverless applications powered by WebAssembly. When Spin is configured to allow connections to a database or web server which could return responses of unbounded size e.g. tables with many rows or large content bodies, Spin may in so...
CVE-2026-27887
CVE-2026-27887 affects Spin and related components where buffering an entire response from a database or HTTP server can exhaust host memory, causing panics/crashes. The issue arises when a guest app inserts large numbers of rows or large content bodies and Spin buffers the full response before d...
