CISA flags three actively exploited Linux kernel flaws

The US Cybersecurity and Infrastructure Security Agency (CISA) has added three Linux kernel vulnerabilities to its Known Exploited Vulnerabilities Catalog (KEV), indicating they are being actively exploited. The flaws, tracked as CVE-2025-39682, CVE-2026-53266, and CVE-2025-39964, are rated as 'critical' or 'high' severity. Red Hat has confirmed exploitation via publicly known exploits. The vulnerabilities can lead to system crashes, privilege escalation, and remote code execution. CISA has ordered US federal agencies to patch affected systems within three days or temporarily take them offline. Patches are available in the kernel, and administrators are urged to apply them urgently. No details on the threat actors or targets have been disclosed yet.

• CISA added three Linux kernel vulnerabilities to its KEV catalog: CVE-2025-39682, CVE-2026-53266, and CVE-2025-39964.
• Red Hat confirmed that all three vulnerabilities are exploited in real attacks via publicly known exploits.
• CVE-2025-39682 involves an error in processing empty TLS records in kernel TLS, potentially leading to system crashes and code injection.

Tokens-per-Second Benchmarks Explained

This technical guide explains what "tokens per second" (tok/s) actually measures for local LLM inference, why single-user tok/s numbers can be misleading, and how concurrency, batching, and prompt processing change the observed speed. It contrasts single-user latency with server throughput, highlights vLLM's continuous-batching advantage versus Ollama under high concurrency, defines related metrics (P99 latency, time to first token / TTFT), and provides practical measurement advice using tools like Ollama and vLLM and calculators from notAcalculator. The article also gives realistic tok/s expectations for different model sizes on consumer hardware and lists practical tips for reading and running benchmarks yourself.

• Tokens are the unit of both billing and speed for LLMs; tokenization affects cost and measured tok/s.
• Under a Red Hat benchmark on an A100 40GB with Llama 3.1 8B, vLLM peaked around 793 tok/s combined throughput versus about 41 tok/s for Ollama at high concurrency (~19x gap).
• vLLM's key innovation is continuous batching (plus PagedAttention), which increases total throughput under concurrency compared with single-request processing tools.
