CVE-2026-90180

A flaw was found in the Linux kernel's mtip32xx block device driver. A local user with access to an already open block device could exploit a synchronization issue between ioctl handlers and device removal. This could lead to a use-after-free vulnerability, where the system attempts to access...

EUVD-2026-42053

MSI Feature Manager contains a local privilege escalation vulnerability in the KernCoreLib64.sys kernel driver that allows any locally logged-on user to perform arbitrary physical memory read/write and unrestricted I/O port operations by accessing exposed IOCTL handlers without administrator...

CVE-2026-8050: Undefined Security Weakness

In SignalRGB versions prior to 1.3.7.0, seven of the thirteen IOCTL handlers dereference the SystemBuffer pointer without first verifying that it is non-NULL. Sending an IOCTL with an empty input buffer causes a NULL pointer dereference, resulting in a kernel crash...

CVE-2026-8501

Improper access control in the PCTCore64.sys Windows kernel driver from PC Tools Internet Security allows user-mode processes to access the PCTCoreDriver WDM device interface and invoke privileged IOCTL handlers. A local attacker with the ability to access or load the affected driver can exploit...

CVE-2026-31769 gpib: fix use-after-free in IO ioctl handlers

In the Linux kernel, the following vulnerability has been resolved: gpib: fix use-after-free in IO ioctl handlers The IBRD, IBWRT, IBCMD, and IBWAIT ioctl handlers use a gpibdescriptor pointer after board-biggpibmutex has been released. A concurrent IBCLOSEDEV ioctl can free the descriptor via...

CVE-2026-31769: Use After Free

In the Linux kernel, the following vulnerability has been resolved: gpib: fix use-after-free in IO ioctl handlers The IBRD, IBWRT, IBCMD, and IBWAIT ioctl handlers use a gpibdescriptor pointer after board-biggpibmutex has been released. A concurrent IBCLOSEDEV ioctl can free the descriptor via...

📄 Microsoft Windows 11 Pro 23H2 Kernel IOCTL Access Control

This Metasploit module exploits an insufficient access control vulnerability in the Windows Kernel through exposed IOCTL handlers. The vulnerability allows non-privileged users to access kernel-level functionality leading to privilege escalation...

CVE-2022-42455

ASUS EC Tool driver aka d.sys 1beb15c90dcf7a5234ed077833a0a3e900969b60be1d04fcebce0a9f8994bdbb, as signed by ASUS and shipped with multiple ASUS software products, contains multiple IOCTL handlers that provide raw read and write access to port I/O and MSRs via unprivileged IOCTL calls. Local user...

CVE-2025-21814 ptp: Ensure info->enable callback is always set

In the Linux kernel, the following vulnerability has been resolved: ptp: Ensure info-enable callback is always set The ioctl and sysfs handlers unconditionally call the -enable callback. Not all drivers implement that callback, leading to NULL dereferences. Example of affected drivers: ptps390.c,...

Qualcomm Chipsets Security Vulnerability

Qualcomm Chipsets are a family of chipsets from Qualcomm Incorporated USA. A security vulnerability exists in Qualcomm Chipsets that stems from a memory corruption issue when handling IOCTL handlers in FastRPC...

CVE-2021-47339

In the Linux kernel, the following vulnerability has been resolved: media: v4l2-core: explicitly clear ioctl input data As seen from a recent syzbot bug report, mistakes in the compat ioctl implementation can lead to uninitialized kernel stack data getting used as input for driver ioctl handlers...
