High [CVE-2026-72130] reject short AUTH_RECEIVE buffers
CVE-2026-72130Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: nvmet-auth: reject short AUTH_RECEIVE buffers nvmet_execute_auth_receive() trusts the AUTH_RECEIVE allocation length after checking only that it is nonzero and matches the transfer length. In the SUCCESS1 and FAILURE1/default states, that lets a remote NVMe-oF initiator reach the fixed-size DH-HMAC-CHAP response builders with a kmalloc() buffer shorter than the response, so nvmet_auth_success1() and nvmet_auth_failure1() write past the allocation; both only WARN_ON the short length and then format the message anyway. Impact: A remote NVMe-oF initiator with access to an auth-enabled target can trigger a 16-byte heap out-of-bounds write via a one-byte AUTH_RECEIVE allocation length. Compute the minimum response length for…

- Mitigation guidance
- To mitigate this issue, ensure that in-band DH-HMAC-CHAP authentication is not configured on NVMe-oF targets if it is not strictly required. This vulnerability is only exploitable when this specific authentication mechanism is enabled. Consult NVMe-oF documentation for your specific setup to disable DH-HMAC-CHAP authentication if it is currently enabled and not required.
