Cloudflare Containers exposed previous tenants’ disk data through unzeroed blocks

This was not a Firecracker escape or access to a live victim disk. It was a storage-isolation failure underneath the sandbox: researchers recovered foreign directory structures, database pages and complete SQLite databases from reused blocks, and Cloudflare had to fix allocation plus retire existing disks and cached snapshots.

GitHub’s OAuth apps get short-lived tokens, multiple callbacks — and a wildcard setting worth auditing

GitHub OAuth apps can now use eight-hour access tokens with rotating refresh tokens, register up to 10 callback URLs, and explicitly control wildcard callback matching. New apps default to expiring tokens, while existing single-callback apps should review a legacy wildcard setting GitHub has now made visible.

Microsoft Project Zenith turns 64GB-class Windows PCs into a standardized local-AI developer tier

Project Zenith is not a new model or another Copilot feature. It standardizes a developer-focused Windows experience and hardware floor for local AI work, with preconfigured tooling and OS settings intended to reduce setup friction and dependence on metered cloud inference.

Docker Desktop is replacing its third-party VM layer with Docker VMM

Docker VMM gives Docker direct control over Desktop’s hidden Linux-VM layer and is still targeted to become the default for new installs at GA. The August 24 Desktop 4.88 release is an important beta signal: it fixes a severe inbound-network-throughput regression and removes a 28 GiB Mac memory ceiling, reinforcing the need for workload-specific testing before standardisation.

OpenSSH 10.6 turns on hybrid post-quantum signatures and disables compression to cut side-channel risk

The release is more than routine maintenance. OpenSSH is changing cryptographic defaults, sacrificing some compression effectiveness for side-channel safety, and warning that AI-assisted security reports are pushing it toward a faster release cadence.

Meta opens Muse Spark’s 816B weights — but large model-as-a-service operators need a separate licence

Meta Muse Spark Open is genuinely downloadable, unlike a promised future weight release. But 42B active parameters do not make its 816B weights cheap to host, and the Muse Model License is not Apache or MIT: model-as-a-service operators over $20M in affiliated annual gross revenue need a separate agreement.
