It's been quite a year for the open source platforms. Earlier this year, Microsoft acquired popular code repository hosting service GitHub for $7.5 billion , and now IBM has just announced the biggest open-source business deal ever. IBM today confirmed that it would be acquiring open source Linux firm Red Hat for $190 per share in cash, working out to a total value of approximately $34 billion. Red Hat, known for its Red Hat Enterprise Linux (RHEL) operating system, is a leading software company that offers open-source software products to the enterprise community. Even Oracle uses Red Hat's source code for its Oracle Linux product. Red Hat's last year revenue was $2.4 billion, and this year the company has earned $2.9 billion. But if Red Hat products are open source and updates are free, you might be wondering how does the company earn. Red Hat was one of the first companies who found a successful way to make money from free open-source software. It offers consul...

A cybersecurity researcher with Google Project Zero has released the details, and a proof-of-concept (PoC) exploit for a high severity vulnerability that exists in Linux kernel since kernel version 3.16 through 4.18.8. Discovered by white hat hacker Jann Horn, the kernel vulnerability (CVE-2018-17182) is a cache invalidation bug in the Linux memory management subsystem that leads to use-after-free vulnerability, which if exploited, could allow an attacker to gain root privileges on the targeted system. The use-after-free (UAF) vulnerabilities are a class of memory corruption bug that can be exploited by unprivileged users to corrupt or alter data in memory, enabling them to cause a denial of service (system crash) or escalate privileges to gain administrative access on a system. Linux Kernel Exploit Takes an Hour to Gain Root Access However, Horn says his PoC Linux kernel exploit made available to the public "takes about an hour to run before popping a root shell....

A Google security researcher has discovered a critical remote command injection vulnerability in the DHCP client implementation of Red Hat Linux and its derivatives like Fedora operating system. The vulnerability, tracked as CVE-2018-1111 , could allow attackers to execute arbitrary commands with root privileges on targeted systems. Whenever your system joins a network, it's the DHCP client application which allows your system to automatically receive network configuration parameters, such as an IP address and DNS servers, from the DHCP (Dynamic Host Control Protocol) server. The vulnerability resides in the NetworkManager integration script included in the DHCP client packages which is configured to obtain network configuration using the DHCP protocol. Felix Wilhelm from the Google security team found that attackers with a malicious DHCP server, or connected to the same network as the victim, can exploit this flaw by spoofing DHCP responses, eventually allowing them to run...

Artificial intelligence is driving a massive shift in enterprise productivity, from GitHub Copilot's code completions to chatbots that mine internal knowledge bases for instant answers. Each new agent must authenticate to other services, quietly swelling the population of non‑human identities (NHIs) across corporate clouds. That population is already overwhelming the enterprise: many companies now juggle at least 45 machine identities for every human user . Service accounts, CI/CD bots, containers, and AI agents all need secrets, most commonly in the form of API keys, tokens, or certificates, to connect securely to other systems to do their work. GitGuardian's State of Secrets Sprawl 2025 report reveals the cost of this sprawl: over 23.7 million secrets surfaced on public GitHub in 2024 alone. And instead of making the situation better, repositories with Copilot enabled the leak of secrets 40 percent more often .  NHIs Are Not People Unlike human beings logging into systems, ...
