Doc Text:	A flaw was found in the `nvmet` component of the Linux kernel. When processing an RMI log page, if memory allocation for the log buffer fails, the system incorrectly reports a successful operation to the host. This can lead to the host believing data was transferred when it was not, potentially causing data integrity issues or unexpected behavior.	Story Points:	---

Description OSIDB Bzimport 2026-09-17 17:18:15 UTC

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.
