CVE-2026-34944

A flaw was found in Wasmtime, a runtime for WebAssembly. On x86-64 platforms with SSE3 disabled, Wasmtime's Cranelift compiler backend may load additional data beyond the intended memory boundary when compiling the 'f64x2.splat' WebAssembly instruction. This out-of-bounds read can lead to a Denia...

GHSA-QQFJ-4VCM-26HV 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...

CVE-2026-5187 Heap Out-of-Bounds Write in DecodeObjectId() in wolfSSL

Two potential heap out-of-bounds write locations existed in DecodeObjectId in wolfcrypt/src/asn.c. First, a bounds check only validates one available slot before writing two OID arc values out0 and out1, enabling a 2-byte out-of-bounds write when outSz equals 1. Second, multiple callers pass...
