CVE-2026-119148 - Unvalidated parent-supplied AWS Region in AWS aws-nitro-enclaves-sdk-c allows impersonation of the enclave's AWS KMS endpoint
CVE-2026-119148 是 AWS aws‑nitro‑enclaves‑sdk‑c 0.4.6 之前版本的漏洞，允許第三方冒充 AWS KMS 端點。
Incomplete string validation in AWS aws-nitro-enclaves-sdk-c before 0.4.6 may allow a third party to impersonate the AWS KMS endpoint. To remediate this issue, users should rebuild any custom enclave image against aws-nitro-enclaves-sdk-c 0.4.6.
