CVE-2026-27144: CWE-440: Expected Behavior Violation in Go toolchain 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.
AI Analysis
Technical Summary
The Go compiler's cmd/compile is designed to unwrap pointers that are operands of memory move operations to ensure safe, non-overlapping moves. However, a no-op interface conversion prevents the compiler from making the correct determination about these moves, potentially leading to memory corruption during program execution. This vulnerability is classified under CWE-440 (Expected Behavior Violation) and impacts Go versions up to 1.26.0-0. There is currently no CVSS score or vendor-provided remediation information available.
Potential Impact
This vulnerability can lead to memory corruption at runtime in programs compiled with affected versions of the Go toolchain. Memory corruption may cause program instability, crashes, or undefined behavior. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should monitor Go toolchain updates and consider avoiding affected versions if possible.
