What is CVE-2026-90412?
CVE-2026-90412 is a denial of service vulnerability in Linux, published on 17 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
In the Linux kernel, the following vulnerability has been resolved:
nvmet: fix return status of RMI log page on allocation failure
nvmet_execute_get_log_page_rmi() leaves 'status' holding NVME_SC_SUCCESS (set by the successful nvmet_req_find_ns() call) when the kzalloc() for the log buffer fails. It then jumps to the out label and completes the request with a success status, so the host is told the command succeeded while no data was transferred.
Initialize 'status' to NVME_SC_INTERNAL, matching the smart log handler, so an allocation failure is reported as an internal error.
