Arbitrary Code Injection

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Arbitrary Code Injection through lib/builtin.js. An attacker can execute host code when the allowlist includes -X or uses and then calls...

GHSA-V8J7-HP7C-738F Kubetail has a Cross-Site WebSocket Hijacking issue that allows attacker to read Kubernetes logs from authenticated users

Summary Kubetail's dashboard exposes WebSocket endpoints that did not adequately validate the Origin header on connection upgrade. A malicious web page visited by a user with an active Kubetail session could open a WebSocket to the user's dashboard and read their Kubernetes logs in real time. Thi...

SUSE CVE-2026-43271

In the Linux kernel, the following vulnerability has been resolved: md-cluster: fix NULL pointer dereference in processmetadataupdate The function processmetadataupdate blindly dereferences the 'thread' pointer acquired via rcudereferenceprotected within the waitevent macro. While the code commen...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal via the compressedEndpoint field in a UIPlugin deployment. An attacker can overwrite binaries or configuration files, tamper with cluster state, or write to the host node filesystem by exploiting path traversal in th...

GHSA-5V3H-X4WF-5C35 Rancher Extensions have arbitrary file access via path traversal

Impact A vulnerability has been identified in Rancher's Extensions where malicious code can be injected in Rancher through a path traversal in the compressedEndpoint field inside a UIPlugin deployment. A malicious UI extension could abuse that to: - Overwrite Rancher binaries or configuration to...

CVE-2026-43271

A flaw was found in the Linux kernel's md-cluster module. During the startup of a multi-device MD array, a race condition can occur where a remote node sends a metadata update message before the system is fully ready to process it. This premature processing leads to a null pointer dereference,...

GHSA-V5MH-H5HX-7V92 kube-router: GoBGP gRPC Admin Port Exposed on Node Primary IP Without Authentication, Allowing Cluster-Wide BGP Route Injection

Summary When the kube-router routing controller starts --run-router, it binds the GoBGP gRPC management server to the node's primary IP e.g., 192.168.1.10:50051 in addition to 127.0.0.1:50051. The default admin port is 50051 and the server is enabled by default with no TLS and no authentication...

Moderate: Red Hat Enhancement Advisory: Red Hat Edge Manager Version 1.1.2

Red Hat Edge Manager Version 1.1.2 Red Hat Edge Manager RHEM provides simple, scalable, and secure management for edge fleets. Users declare their target OS image, host configuration, and applications; the RHEM agent then automatically rolls out these configurations, reporting health and progress...

Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation in the SUSE Virtualization Harvester Rancher integration mechanism. An attacker can intercept sensitive information and cause a crash of the registration controller by exploiting insecure TLS certificate...

GHSA-PGH9-MPWC-8JJF Harvester's SUSE Virtualization Registration Client Vulnerable to MITM and DOS

Impact A vulnerability has been identified in the SUSE Virtualization Harvester Rancher integration mechanism where by default the registration client uses an insecure TLS option that fails to verify the remote server’s certificate. This security gap could allow the execution of a man-in-the-midd...

CVE-2026-43168

A flaw was found in the Linux kernel's Oracle Cluster File System version 2 ocfs2. This vulnerability arises from an issue in the reflink preserve cleanup process, where the system incorrectly handles extended attribute xattr entries. The cleanup logic fails to properly manage pointers and clean ...

CVE-2026-43274

A flaw was found in the Linux kernel's mailbox subsystem, specifically within the mchp-ipc-sbi component. This vulnerability involves an out-of-bounds access in the mchpipcgetclusteraggrirq function. The clustercfg array, which holds per-CPU configuration structures, was incorrectly indexed using...
