CVSS 3.1
7.1 highCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:HCVE-2026-27144
High (7.1) in golang go. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in toolchain 1.25.9, 1.26.2.
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.
