ioctl vulnerability

About this tag
The ioctl vulnerability tag on WindowsForum.com covers discussions about input/output control (ioctl) bugs that can lead to denial-of-service or other security issues. Tagged content includes analysis of CVE-2024-23851, a Linux kernel device-mapper ioctl flaw where a missing bounds check in copy_params could allow an ioctl request to trigger excessive memory allocation and crash the system. While the primary focus is on Linux kernel vulnerabilities, the tag may also touch on broader ioctl security concepts relevant to operating system robustness and patch management.

    CVE-2024-23851 DM IOCTL Patch: Linux Kernel Robustness Fix

    The Linux kernel received a targeted robustness fix for a device‑mapper ioctl bug tracked as CVE‑2024‑23851: a missing check in copy_params (drivers/md/dm-ioctl.c) could let an ioctl request lead the kernel to try to allocate more than INT_MAX bytes and crash, producing a local denial‑of‑service...
