  • How To Set Up Redis as a Cache for MySQL with PHP on Ubuntu 20.04

    Redis is an open-source and in-memory data structure store that can be used for caching, real-time analytics, searching, and machine learning. Integrate Redis with PHP and MySQL will improve your application performance because Redis stores data in RAM. You can use it with databases like MySQL or MariaDB. Redis provides a mechanism to cache your queries. For example, when a user requests your application page the first time, a MySQL query is performed on the server, and Redis caches this query to RAM. When another user requests the same page, you don’t need to query the database again.

  • Now-fixed Linux kernel vulnerabilities enabled local privilege escalation (CVE-2021-26708)

    The vulnerabilities could be exploited for local privilege escalation, as confirmed in experiments on Fedora 33 Server. The vulnerabilities, known together as CVE-2021-26708, have received a CVSS v3 base score of 7.0 (high severity). These vulnerabilities result from race conditions that were implicitly added with virtual socket multi-transport support. They appeared in Linux kernel version 5.5 in November 2019. The vulnerable kernel drivers (CONFIG_VSOCKETS and CONFIG_VIRTIO_VSOCKETS) are shipped as kernel modules in all major GNU/Linux distributions. The vulnerable modules are automatically loaded when an AF_VSOCK socket is created. This ability is available to unprivileged users.
