CVE-2026-90227NVD

Vulnerability Summary

In the Linux kernel, the following vulnerability has been resolved:

nvme/ioctl: check SUBMIT_IO with nvme_cmd_allowed()

Unlike IO_CMD / IO64_CMD, NVME_IOCTL_SUBMIT_IO never calls
nvme_cmd_allowed(). Unprivileged callers can thus issue I/O on a
partition device or write through a read-only file descriptor.

Pass flags and open_for_write through and reject disallowed commands
with -EACCES.
