Ещё одна уязвимость в PHP, в редких конфигурациях позволяющая удалённо выполнить код

Разработчики проекта PHP предупредили о выявлении ещё одной уязвимости (CVE-2026-115560), которая потенциально может использоваться для удалённого выполнения кода на сервере при определённом редком сочетании нестандартных настроек (не в конфигурации по умолчанию) и выполняемого PHP-кода. Подробности о уязвимости намерены опубликовать после готовности очередных корректирующих выпусков PHP.

CheriBSD — FreeBSD с аппаратной защитой памяти CHERI

CheriBSD – специализированная операционная система, которая развивается при участии исследователей из Кембриджского университета и SRI International. Система поддерживает платформу Arm Morello и экспериментальную архитектуру CHERI-RISC-V. Исходный код и инструментарий доступны открыто.
Главная особенность проекта – использование аппаратно проверяемых привилегий (capabilities) вместо обычных указателей. Такая привилегия содержит адрес, границы доступной памяти и разрешения на выполнение операций. Процессор проверяет эти ограничения при обращении к памяти, что позволяет обнаруживать выходы за границы объектов и ограничивать последствия ошибок работы с указателями.
Механизмы CHERI интегрированы не только в пользовательские приложения, но и в ядро, системные библиотеки, ABI и средства отладки. Это позволяет экспериментировать с защитой существующего кода на C и C++, не требуя полного перехода на языки с проверками безопасности памяти на уровне компилятора, такие как Rust.

OpenAI cuts Habitat read latency 12x as storage scales globally

OpenAI’s Habitat is a globally distributed online storage platform built on Azure Cosmos DB, serving products across 40 regions. OpenAI says it cut median global read latency from about 120 ms to 10 ms while scaling Habitat to more than 500 petabytes. The changes also let it return to shared database containers without the noisy-neighbor incidents that had driven it toward dedicated ones.

Windows Server 2025 October update KB5126646: Quick machine recovery, ReFS hardening, NTLMv1 enforcement

October 2026 cumulative update KB5126646 (OS Build 26100.33650) introduces Quick machine recovery (QMR) on Windows Server 2025, complete with Group Policy knobs to manage it. That same package begins auditing ReFS volumes on removable media and changes the default for NTLMv1-derived credentials from audit to enforce. Hybrid ML-KEM key exchange was already available on Windows Server 2025 with the July 14, 2026 update KB5099536 (OS Build 26100.33158). Installing KB5126646 does not make TLS 1.3 start using ML-KEM. The groups stay disabled until an administrator enables them, and a TLS 1.3 handshake still uses the classic default groups. Documented known issues hit on-premises Exchange Server and WSUS error reporting.

Local AI’s cost, trade-offs, and path forward

Matthew Berman argues that local AI is not yet a practical replacement for hosted services such as ChatGPT and Claude for most people. High hardware costs, setup effort, and weaker performance can make local models less useful for getting work done. Still, he sees data control, independence from AI providers, and distributed access to intelligence as reasons to keep developing local AI.

Shader Effects is the coolest GNOME extension you’ll try this weekend

Ever wondered what your Ubuntu desktop would look like if you were watching it on a chewed up VHS tape or an old monochrome CRT monitor? You probably haven’t, but a new GNOME Shell extension lets you find out anyway. The Shader Effects extension applies different GPU-accelerated filters (things like fuzzy scan lines, NTSC RGB bloom and flickery green CRT glow) to the entire desktop, or just a specific window if you’d rather. Settings allow you to fine-tune how intense the effect is, and dial in (or disable) animation speed and frame rate. The higher those values are, the more […]

BlackX keeps Secure Boot bypass alive when Windows revocations are missing

BlackX, a UEFI bootkit targeting Windows systems, can still exploit the patched Baton Drop flaw when organizations have not applied the required Secure Boot revocation. The campaign targeting diplomatic organizations in Central Asia uses the BlackLotus-derived malware for stealthy persistence after attackers gain administrator access.

Axia 0.3.0 — веб-консоль для Samba AD, OpenLDAP и Active Directory

Вышла версия 0.3.0 Axia — свободной (Apache 2.0) веб-консоли и REST API для управления LDAP-каталогами. Через браузер можно управлять пользователями, группами, OU и учётными записями компьютеров. Поддерживаются OpenLDAP, Samba AD и Active Directory, а также любой сервер со стандартным LDAP (RFC 4511) поверх LDAPS или StartTLS.
Задача проекта — отдать рутину (заведение учёток, сброс паролей, группы) техподдержке и кадровикам, не раздавая им доступ к каталогу. Консоль работает от имени одной служебной учётной записи с делегированными правами. Права операторов назначаются через группы каталога и могут только сужать полномочия служебной учётки. Изменять учётные записи с бо́льшими правами, чем у самого оператора, нельзя. Все действия, включая отклонённые попытки, пишутся в журнал аудита.

Kimi K3.1 review and benchmarks

Matthew Berman tests Kimi K3.1, an open-weight model described as a roughly 3-trillion-parameter system, across 3D projects, games, video, and benchmark tasks. It creates an interactive Rubik’s Cube simulation and several polished visual outputs, but struggles with some tasks that require precise geometry or instructions. Berman also examines its published benchmark results, model specifications, and pricing.
