4 vulnerabilities found for cmd/compile by Go toolchain

CVE-2026-27144 (GCVE-0-2026-27144)

Vulnerability from nvd – Published: 2026-04-08 01:06 – Updated: 2026-04-08 01:06
VLAI?
Title
Miscompilation allows memory corruption via CONVNOP-wrapped array copy in cmd/compile
Summary
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.
Severity ?
No CVSS data available.

CVE-2026-27143 (GCVE-0-2026-27143)

Vulnerability from nvd – Published: 2026-04-08 01:06 – Updated: 2026-04-08 01:06
VLAI?
Title
Missing bound checks can lead to memory corruption in safe Go in cmd/compile
Summary
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.
Severity ?
No CVSS data available.
