OpenStack Compute nova before 2014.2.4 juno and 2015.1.x before 2015.1.2 kilo does not properly delete instances from compute nodes, which allows remote authenticated users to cause a denial of service disk consumption by deleting instances while in the resize state...

ThreatsDay: AI Compute Hijacking, Apple Email Flaw, BlueHammer Ransomware + 14 Stories

This week’s security news is mostly about weak spots. Browsers, bots, sandboxes, AI systems, and email flows all show the same problem in different ways. Everything looks normal until someone tests a small gap and finds a way through. This is not one big break. It is small permissions, weak check...

PYSEC-2026-689 OpenStack Nova Denial of service attack on the compute host

An issue was discovered in OpenStack Nova 15.x through 15.1.0 and 16.x through 16.1.1. By detaching and reattaching an encrypted volume, an attacker may access the underlying raw volume and corrupt the LUKS header, resulting in a denial of service attack on the compute host. The same code error...

PYSEC-2026-652 OpenStack Keystone allows context-dependent attackers to bypass access restrictions

OpenStack Keystone Grizzly before 2013.1, Folsom 2012.1.3 and earlier, and Essex does not properly check if the 1 user, 2 tenant, or 3 domain is enabled when using EC2-style authentication, which allows context-dependent attackers to bypass access restrictions...

PYSEC-2026-656 OpenStack Keystone and other components vulnerable to Improper Certificate Validation

HTTPSConnections in OpenStack Keystone 2013, OpenStack Compute 2013.1, and possibly other OpenStack components, fail to validate server-side SSL certificates...

PYSEC-2026-691 OpenStack Nova Exposure of Sensitive Information to an Unauthorized Actor

OpenStack Nova before 2012.1 allows someone with access to an EC2ACCESSKEY equivalent to a username to obtain the EC2SECRETKEY equivalent to a password. Exposing the EC2ACCESSKEY via http or tools that allow man-in-the-middle over https could allow an attacker to easily obtain the EC2SECRETKEY. A...

CVE-2026-53283

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Bounds-check devid in rlookupamdiommu iommudeviceregister walks every device on the PCI bus via busforeachdev and calls amdiommuprobedevice for each. The inlined checkdevice path computes the device's sbdf, calls...

CVE-2026-53139

A flaw was found in the Linux kernel's graphics driver for Broadcom V3D VideoCore V GPUs. This vulnerability occurs when a compute shader dispatch CSD is initiated with zero workgroup counts, which the hardware could misinterpret as a very large number. This misinterpretation could lead to...
