CVE-2026-90975

A vulnerability in Realtek's RtUsbA64.sys USB audio driver allows a local, low-privileged user to abuse a kernel I/O control (IOCTL) interface that acts on a caller-supplied user-mode pointer without proper validation or capture. By issuing crafted property requests an attacker can obtain kernel-mode read and write access, which can be leveraged for local privilege escalation and arbitrary kernel code execution.

CVE-2026-122113

A vulnerability in Realtek's RtUsbA64.sys USB audio driver allows a physically present attacker using a maliciously crafted USB device to trigger unbounded recursion in the driver's topology-parsing logic during device enumeration. Processing the crafted descriptor exhausts the kernel stack and causes a system crash (bugcheck), resulting in a denial of service. No authenticated user session is required.

A stack-based buffer overflow vulnerability exists in the boa formRoute functionality of Realtek rtl819x Jungle SDK v3.4.11. A specially crafted series of HTTP requests can lead to remote code execution. An attacker can send an HTTP request to trigger this vulnerability.

Realtek High definition audio Windows driver crashed

Realtek HAD contains a driver crashed vulnerability which allows local side attackers to send a special string to the kernel driver in a user’s mode. Due to unexpected commands, the kernel driver will cause the system crashed.

Realtek Audio Service 1.0.0.55 Unquoted Service Path Privilege Escalation

Realtek Audio Service 1.0.0.55 contains an unquoted service path vulnerability in RtkAudioService64.exe that allows local attackers to escalate privileges by injecting malicious code. Attackers can place executable files in the unquoted service path directory to execute arbitrary code with LocalSystem privileges during service startup or system reboot.

Realtek High Definition Audio Driver 6.0.1.6730 Privilege Escalation

Realtek High Definition Audio Driver 6.0.1.6730 contains an unquoted service path vulnerability that allows local attackers to escalate privileges by placing a malicious executable in the service path. Attackers can insert an executable file in the unquoted path and restart the service to execute code with LocalSystem privileges.

Privilege Escalation via Unchecked Debug IOCTLs in Realtek RTL8192CD Wi‑Fi Driver

The rtl8192cd Wi-Fi kernel driver in the Realtek rtl819x Jungle SDK (all known versions through v3.4.14B) does not perform any access control checks on the write_mem (ioctl 0x89F5) and read_mem (ioctl 0x89F6) debug handlers, which are compiled into production builds via the unconditionally defined _IOCTL_DEBUG_CMD_ macro in 8192cd_cfg.h

Stack-based buffer overflow in Realtek Media Player (aka Realtek Sound Manager, RtlRack, or rtlrack.exe) 1.15.0.0 allows remote attackers to execute arbitrary code via a crafted playlist (PLA) file.

Realtek HD Audio Codec Drivers RTKVHDA.sys and RTKVHDA64.sys before 6.0.1.5605 on Windows Vista allow local users to create, write, and read registry keys via a crafted IOCTL request.

Integer overflow in Realtek HD Audio Codec Drivers RTKVHDA.sys and RTKVHDA64.sys before 6.0.1.5605 on Windows Vista allows local users to execute arbitrary code via a crafted IOCTL request.

The miniigd SOAP service in Realtek SDK allows remote attackers to execute arbitrary code via a crafted NewInternalClient request, as exploited in the wild through 2023.

An issue in the component rtkio64.sys of Realtek Semiconductor Corp Realtek lO Driver v1.008.0823.2017 allows attackers to escalate privileges and execute arbitrary code via sending crafted IOCTL requests.

A lack of input validation in Realtek SD card reader driver before 10.0.26100.21374 through the implementation of the IOCTL_SCSI_PASS_THROUGH control of the SD card reader driver allows an attacker to write to predictable kernel memory locations, even as a low-privileged user.

An issue was discovered in the NDIS Usermode IO driver (RtkIOAC60.sys, version 6.0.5600.16348) allowing local authenticated attackers to send a crafted IOCTL request to the driver to cause a denial of service.

RTK IIS Codec Service 6.4.10041.133 - 'RtkI2SCodec' Unquote Service Path

Realtek IIS Codec Service 6.4.10041.133 contains an unquoted service path vulnerability that allows local attackers to potentially execute arbitrary code. Attackers can exploit the unquoted path in the service configuration to inject malicious executables and escalate privileges on the system.

Realtek Andrea RT Filters 1.0.64.7 - 'AERTSr64.EXE' Unquoted Service Path

Realtek Andrea RT Filters 1.0.64.7 contains an unquoted service path vulnerability that allows local users to potentially execute arbitrary code with elevated system privileges. Attackers can exploit the unquoted path in 'C:\Program Files\IDT\WDM\AESTSr64.exe' to inject malicious code that would execute during service startup or system reboot.

Realtek Wireless LAN Utility 700.1631 - 'Realtek11nSU' Unquoted Service Path

Realtek Wireless LAN Utility 700.1631 contains an unquoted service path vulnerability that allows local users to potentially execute code with elevated system privileges. Attackers can exploit the unquoted service path by inserting malicious code in the system root path that would execute during application startup or system reboot.

A lack of input validation in Realtek SD card reader driver before 10.0.26100.21374 through the implementation of the IOCTL_SFFDISK_DEVICE_COMMAND control of the SD card reader driver allows a privileged attacker to crash the OS.

An issue in the Bluetooth Low Energy implementation of Realtek RTL8762E BLE SDK v1.4.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted ll_terminate_ind packet.

Realtek Jungle SDK version v2.x up to v3.4.14B provides a diagnostic tool called 'MP Daemon' that is usually compiled as 'UDPServer' binary. The binary is affected by multiple memory corruption vulnerabilities and an arbitrary command injection vulnerability that can be exploited by remote unauthenticated attackers.
