CVE-2026-27144Miscompilation allows memory corruption via CONVNOP-wrapped array copy in cmd/compile

Go toolchain cmd/compile Veröffentlicht: 2026-04-08 04:06 (vor 7 Monaten)

Beschreibung

The compiler is meant to unwrap pointers which are the operands of a memory move; a no-op interface conversion prevented the compiler from making the correct determination about non-overlapping moves, potentially leading to memory corruption at runtime.
