CVE-2026-27143

A flaw was found in the cmd/compile package in the Go standard library. The compiler fails to correctly check for integer overflow or underflow in arithmetic operations involving loop induction variables. As a result, the compiler allows invalid memory indexing to occur at runtime, potentially leading to memory corruption.

CVE-2026-27144

A flaw was found in the cmd/compile package in the Go standard library. A no-op interface conversion prevented the compiler from correctly identifying non-overlapping memory moves. As a result, the compiler allows unsafe memory move operations to occur at runtime, potentially causing data corruption, memory corruption or unexpected application behavior.

CVE-2026-32280

A flaw was found in the Go standard library packages `crypto/x509` and `crypto/tls`. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being performed. This can result in a denial of service (DoS) condition, making the affected system or application unavailable to legitimate users.

Additionally, an attacker must be able to cause an integer overflow or underflow in the induction variable to trigger this issue.
