Linux Kernel Security Vulnerabilities

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the failure of the connection preparation in the mac80211 module. This failure results in the site not...

CVE-2026-42398: Server-Side Request Forgery (SSRF)

Server-Side Request Forgery CWE-918 in Kibana allows authenticated users with connector management privileges to bypass the operator-configured connection allowlist. By configuring a Webhook connector with a crafted target, an attacker can cause Kibana to issue outbound requests to destinations...

CVE-2026-45956

A flaw was found in the Linux kernel's drm/exynos component. This vulnerability arises from an incorrect lookup of device information within the vidiconnectionioctl function, where the system uses an improper pointer to access data. This can lead to memory corruption, which means the system might...

EUVD-2026-32676

Microsoft UFO open-source framework for intelligent automation across devices and platforms. In 3.0.1-4-ge2626659, Microsoft UFO creates one shared UFOWebSocketHandler instance and reuses it for multiple authenticated WebSocket connections. The handler stores per-connection protocol objects in...

CVE-2026-46416

Microsoft UFO (open-source framework for intelligent automation) in version 3.0.1-4-ge2626659 uses a single shared UFOWebSocketHandler instance for multiple authenticated WebSocket connections. The handler caches per-connection protocol objects in mutable fields, and each new connection overwrite...

Denial of Service (DoS)

Overview Affected versions of this package are vulnerable to Denial of Service DoS via the apiHandler and webHandlerTelegramBot processes. An attacker can cause the application to exhaust system memory and crash by sending an extremely large or endless JSON payload over a single TCP connection...

CVE-2026-44724 systeminformation: Linux command injection in networkInterfaces() via unsanitized NetworkManager connection profile name

systeminformation is a System and OS information library for node.js. From 4.17.0 to 5.31.5, on Linux, systeminformation is vulnerable to command injection in networkInterfaces when an active NetworkManager connection profile name contains shell metacharacters. The vulnerable value is obtained...

CVE-2026-46056

A flaw was found in the Linux kernel's Bluetooth subsystem. This vulnerability, a Use-After-Free UAF, exists within the Secure Simple Pairing SSP passkey handlers. It occurs when hciconn lookup and field access are performed without proper locking, allowing a connection to be freed concurrently...

CVE-2026-4390 TeamSpeak 3 Server Connection State Management process_resend_queue use after free

A weakness has been identified in TeamSpeak 3 Server up to 3.13.7. This affects the function processresendqueue of the component Connection State Management. This manipulation causes use after free. The attack may be initiated remotely. Upgrading to version 3.13.8 is able to mitigate this issue...

EUVD-2026-32242

In the Linux kernel, the following vulnerability has been resolved: drm/exynos: vidi: fix to avoid directly dereferencing user pointer In vidiconnectionioctl, vidi-ediduser pointer is directly dereferenced in the kernel. This allows arbitrary kernel memory access from the user space, so instead o...
