CVE-2023-53576

CVE-2023-53576 affects the Linux kernel’s null_blk driver. The patch ensures queue mode is always validated from configfs by checking queue_mode in null_validate_conf() and returning an error for NULL_Q_RQ to prevent a NULL I/O path OOPs when queue_mode is set to 1. Reproduction steps are provide...
