OVSwrap (CVE-2026-64531): 13-Year-Old Linux Kernel Bug in Open vSwitch Gives Any Local User Root
A 16-bit integer wraparound in the Linux kernel's Open vSwitch action parser (CVE-2026-64531, 'OVSwrap') lets any unprivileged local user become root — no OVS configuration, no CAP_NET_ADMIN, no container privileges required. A public PoC ships precomputed offsets for ~800 kernel builds.
15 TP-Link Omada Flaws Turn Zero-Touch Provisioning Into a Network Takeover Path
Forescout's Vedere Labs found 15 flaws in TP-Link's Omada zero-touch provisioning ecosystem — hardcoded crypto keys, a predictable RC4 cipher, and weak cert validation that chain into full controller and fleet compromise.

An authentication bypass in N-able's N-central RMM platform, tracked as CVE-2026-18556, was exploited in the wild to gain admin access and pivot into managed customer environments using Take Control and rogue Cloudflare tunnels.
The Tenant Boundary Is a Fiction: Inside 2026's Cloud Cross-Tenant Bug Class
Five major cross-tenant breaks in twelve months — Cosmos DB, Vertex AI, Entra ID, AKS Backup — share one root cause: a privileged control-plane identity that trusts a customer-supplied name, key, or token it should never have accepted. Here's the pattern, and what to actually do about it.
CosmosEscape: Gremlin Sandbox Escape Exposed a Master Key to Every Azure Cosmos DB Database
Wiz Research chained a .NET reflection bypass in Cosmos DB's Gremlin API into code execution on Microsoft's multi-tenant gateway, recovering a platform-wide signing key that could pull the primary key for any customer's database.
Adform Ad-Tech Script Hijacked to Swap Crypto Wallet Addresses, Linked to a Midnight Blizzard Sub-Cluster
Attackers compromised an Adform JavaScript library served across thousands of customer sites, silently swapping copied crypto wallet addresses in an operation researchers track as CaptiveCrunch and attribute to a Midnight Blizzard (APT29) sub-cluster.

Copilot for Word Can Be Turned Into a Self-Propagating AI Worm — No Comprehensive Fix After 144 Days
Researcher Håkon Måløy's 'Context Collapse, Part 3' shows hidden document instructions can make Copilot for Word rewrite content and copy the payload into every new file it touches — and Microsoft's fixes, including a model upgrade to GPT-5.5, haven't closed the underlying attack class.
