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.
