CVE-2026-27144
High · 7.1
CWE-843 Apr 7, 2026
Miscompilation allows memory corruption via CONVNOP-wrapped array copy in cmd/compile
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.

Missing bound checks can lead to memory corruption in safe Go in cmd/compile
Arithmetic over induction variables in loops were not correctly checked for underflow or overflow. As a result, the compiler would allow for invalid indexing to occur at runtime, potentially leading to memory corruption.
