golang: cmd/compile: possible memory corruption after bound check elimination

A flaw was found in the cmd/compile package in the Go standard library. The compiler fails to correctly check for integer overflow or underflow in arithmetic operations involving loop induction variables. As a result, the compiler allows invalid memory indexing to occur at runtime, potentially...

golang: cmd/compile: no-op interface conversion bypasses overlap checking

A flaw was found in the cmd/compile package in the Go standard library. A no-op interface conversion prevented the compiler from correctly identifying non-overlapping memory moves. As a result, the compiler allows unsafe memory move operations to occur at runtime, potentially causing data...

Linux Distros Unpatched Vulnerability : CVE-2026-34946

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. From 25.0.0 to before 36.0.7, 42.0.2, and 43.0.1, Wasmtime's Winch compiler contains a vulnerability where the compilatio...

CVE-2026-34946: Always-Incorrect Control Flow Implementation

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 contains a vulnerability where the compilation of the table.fill instruction can result in a host panic. This means that a valid guest can be compiled with Winch, on any architecture...

CVE-2026-34945: Incorrect Conversion between Numeric Types

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 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...

WasmTime security vulnerability

Wasmtime is a lightweight WebAssembly runtime open source by the Bytecode Alliance. Versions of Wastime prior to 25.0.0, 36.0.7, 42.0.2, and 43.0.1 contained security vulnerabilities. These vulnerabilities stemmed from the Winch compiler incorrectly translating the table.size instruction, which i...

PT-2026-31686

Name of the Vulnerable Software and Affected Versions Wasmtime versions 25.0.0 through 36.0.6, 42.0.2, and 43.0.1 Description Wasmtime's Winch compiler has a flaw in how it handles the table.size instruction with 64-bit tables, part of the WebAssembly memory64 proposal. This can lead to the...

CVE-2026-27144
