CyberRota Analysis
AI-GeneratedThe vulnerability in the Linux kernel affects the NVMe driver, where unprivileged users can exploit the NVME_IOCTL_SUBMIT_IO command to perform unauthorized I/O operations on partition devices or write to read-only file descriptors. This could lead to data corruption or unauthorized data access. System administrators and security teams managing Linux environments should prioritize this issue to mitigate potential risks associated with unauthorized access and data integrity violations.
Original NVD Description
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.
