### Summary A user with the ability to launch a container with a custom image (e.g a member of the ‘incus’ group) can use directory traversal or symbolic links in the templating functionality to achieve host arbitrary file read, and host arbitrary file write, ultimately resulting in arbitrary command execution on the host. This can also be exploited in IncusOS. ### Details When using an image with a `metadata.yaml` containing templates, both the source and target paths are not checked for symbolic links or directory traversal. [1] [2] For example, the following `metadata.yaml` snippet can read an arbitrary file from the host root filesystem as root, and place it inside the container: ``` templates: /shadow: when: - start template: ../../../../../../../../etc/shadow ``` Additionally, the path of the target of the template is not checked or opened safely, and can therefore contain symbolic links pointing outside the container root filesystem. For example: ``` template...

A team of academics from the CISPA Helmholtz Center for Information Security in Germany has disclosed the details of a new hardware vulnerability affecting AMD processors. The security flaw, codenamed StackWarp, can allow bad actors with privileged control over a host server to run malicious code within confidential virtual machines (CVMs), undermining the integrity guarantees provided by AMD

Microsoft on Tuesday rolled out its first security update for 2026, addressing 114 security flaws, including one vulnerability that it said has been actively exploited in the wild. Of the 114 flaws, eight are rated Critical, and 106 are rated Important in severity. As many as 58 vulnerabilities have been classified as privilege escalation, followed by 22 information disclosure, 21 remote code

Certain motherboard models from vendors like ASRock, ASUSTeK Computer, GIGABYTE, and MSI are affected by a security vulnerability that leaves them susceptible to early-boot direct memory access (DMA) attacks across architectures that implement a Unified Extensible Firmware Interface (UEFI) and input–output memory management unit (IOMMU). UEFI and IOMMU are designed to enforce a security

Three security vulnerabilities have been disclosed in the Peripheral Component Interconnect Express (PCIe) Integrity and Data Encryption (IDE) protocol specification that could expose a local attacker to serious risks. The flaws impact PCIe Base Specification Revision 5.0 and onwards in the protocol mechanism introduced by the IDE Engineering Change Notice (ECN), according to the PCI Special

Microsoft closed out 2025 with patches for 56 security flaws in various products across the Windows platform, including one vulnerability that has been actively exploited in the wild. Of the 56 flaws, three are rated Critical, and 53 are rated Important in severity. Two other defects are listed as publicly known at the time of the release. These include 29 privilege escalation, 18 remote code

Red Hat is excited to announce the release of Red Hat OpenShift sandboxed containers 1.11 and Red Hat build of Trustee 1.0, marking a significant milestone in our confidential computing journey. These releases bring production-grade support for confidential containers in Microsoft Azure Red Hat OpenShift and introduce technology preview support for bare metal environments with Intel TDX and AMD SEV-SNP processors. Organizations can now protect their most sensitive workloads with hardware-based memory encryption and attestation capabilities across cloud and on-premises infrastructure. OpenShift

Confidential computing is needed to protect sensitive data not only when it is stored or transmitted, but also while it is actively being processed in memory - traditionally the most vulnerable phase. In this article, I demonstrate how to implement a secure runtime environment using AWS Nitro Enclaves for applications on EC2 instances running Red Hat Enterprise Linux 9.6+ (RHEL).To fully understand the concepts, use cases, and justifications for confidential computing, read our previous articles. The hardware used to provide secure communication and certification is based on AWS Nitro architec

Researchers built an inexpensive device that circumvents chipmakers' confidential computing protections and reveals weaknesses in scalable memory encryption.

Microsoft on Tuesday released patches for 63 new security vulnerabilities identified in its software, including one that has come under active exploitation in the wild. Of the 63 flaws, four are rated Critical and 59 are rated Important in severity. Twenty-nine of these vulnerabilities are related to privilege escalation, followed by 16 remote code execution, 11 information disclosure, three
