[PATCH] killswitch: add per-function short-circuit mitigation primitive [LWN.net]

feat: disable kernel modules to mitigate dirtyfrag by HastD · Pull Request #2212 · secureblue/secureblue

This disables the kernel modules that provide support for ESP (Encapsulating Security Payload) and RxRPC, which are involved in the recently disclosed "dirtyfrag" kernel exploit.

Trees halve urban heat island effect globally but unequal benefits only modestly mitigate climate-change warming - Nature Communications

Using global data from 9,000 cities, the study shows trees reduce half of the urban heat island effect but can offset only a small share of future climate warming, with cooling benefits unevenly distributed and lowest where heat risk is highest.

How Cloudflare responded to the “Copy Fail” Linux vulnerability

When a critical Linux kernel privilege escalation was publicly disclosed, Cloudflare's security and engineering teams detected, investigated, and mitigated the threat across our global fleet, confirming zero customer impact and no malicious exploitation.

Extreme heat and agriculture

Extreme heat is emerging as one of the most urgent and least understood threats to agriculture and food security. Rising temperatures, prolonged heatwaves, and shifting climate patterns are already disrupting crop yields, livestock health, water availability, and rural livelihoods – with impacts falling disproportionately on the most vulnerable.Because extreme heat is predictable, strengthening climate services and early warning systems linked to anticipatory actions is a key opportunity. It is also clear that there are profound limits to what adaptation can achieve. With global mean temperatures on the cusp of exceeding the 1.5 °C warming limit outlined in the Paris Agreement, the urgency for adaptation and mitigation action only grows. The only durable solution to protect the future of global agrifood systems from the escalating threat of extreme heat lies in ambitious, multilateral climate change mitigation.
