Detailsinfo

A vulnerability, which was classified as critical, has been found in cmd-compile up to 1.25.8/1.26.1 on Go. This issue affects an unknown code block. The manipulation of the argument induction with an unknown input leads to a integer overflow vulnerability. Using CWE to declare the problem leads to CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The identification of this vulnerability is CVE-2026-27143 since 02/17/2026. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.

Upgrading to version 1.25.9 or 1.26.2 eliminates this vulnerability.
