After 8 release candidates, Linus Torvalds has finally released Linux Kernel 5.3. It is a major upgrade that brings many new features in terms of better hardware support, changes specific to Arm architecture and a couple of bug fixes. The extra release candidate RC8, as Torvalds says, was because of his busy travel schedule. Nonetheless, […]
Linux 5.2 Linux creator Linus Torvalds has released the latest kernel Linux 5.2 on its expected release date. The 5.2 kernel is here after the usual seven Release Candidate and development efforts of Linux developers spread all across the world. In his release announcement, Linus wrote that he was inclined towards delaying the kernel release […]
We keep coming across various security loopholes in different software on a daily basis, but it rarely happens that Linux kernel gets crippled by a high-impact flaw. However, things are looking a bit different today as millions of Linux systems have been found to be affected by a massive flaw. It’s being reported that the […]
Linux boss Linus Torvalds has released the stable version of Linux kernel 5.1 after seven release candidates. Kernel releases generally achieve the stable status after seven or eight release candidates, so it’s great for Linux 5.1 to take shape a week early. Also, the “Shy Crocodile” codename of the latest release remains the same as the past […]
This software project is a result of a Bachelor’s thesis created at SCHUTZWERK in collaboration with Aalen University by Philipp Schmied.Please refer to the corresponding blog post for more information. Why another CAN tool? Built from scratch with new ideas for analysis mechanisms Bundles features of many other tools in one place Modular and extensible: […]
Linus Torvalds has released Linux kernel 4.20 (it looks like we’re not getting Linux 5.0 anytime soon). This reminds me of last year’s Linux 4.9, which turned out to be the biggest ever kernel in terms of the number of commits. Talking about the latest Linux 4.20, it’s a big kernel as well. As per […]
Ever since Linus Torvalds announced the release of Linux kernel 4.16, the open source enthusiasts found themselves making predictions regarding the Linux 5.0. Even though Torvalds had already wished 5.0 release to be “meaningless,” it was being expected that kernel 4.17 could actually end up being kernel 5.0. But that didn’t happen. The Linux boss chose […]
If you follow Linux kernel development closely, you must be knowing that major version transitioning, i.e., jump from Linux 2.0 to 3.0 and 3.0 to 4.0, has taken place in the past at every two million Git objects. This made perfect sense to make a transition to Linux v5.0 at 6 million Git objects landmark. In […]
Whenever a new Linux kernel is released, it adds tons of new code to support some new hardware. Coupled with driver changes, fixes, and networking code, each release gets bulkier by thousands of lines of code. In case of upcoming Linux 4.17, the kernel is expected to lose some weight. This change will take place […]
After releasing the new kernel update for Ubuntu 16.04 LTS (Xenial Xerus) systems to patch 13 security vulnerabilities, Canonical announced the availability of a major kernel update for Ubuntu 17.10. If you’re using the latest Ubuntu 17.10 (Artful Aardvark) operating system on your personal computer, you should know that it received it’s first major kernel update since the […]
Prochunter aims to find hidden process with all userspace and most of the kernelspace rootkits. This tool is composed of a kernel module that prints out all running processes walking the task_struct list and creates /sys/kernel/proc_hunter/set entry. A python script that invokes the kernel function and diffs the module output with processes list collected from userspace (/proc […]
Last month, in September, Linux kernel developer Greg Kroah-Hartman confirmed on his blog Linux kernel 4.14 as the next LTS kernel, which will be supported for at least two years; this number has recently been increased to six years. As a result, the development cycle of Linux 4.14 got a week longer than usual and we […]
Diamorphine is a LKM rootkit for Linux Kernels 2.6.x/3.x/4.x Features When loaded, the module starts invisible; Hide/unhide any process by sending a signal 31; Sending a signal 63(to any pid) makes the module become (in)visible; Sending a signal 64(to any pid) makes the given user become root; Files or directories starting with the MAGIC_PREFIX become […]
Security researchers have discovered a new privilege-escalation vulnerability in Linux kernel that could allow a local attacker to execute code on the affected systems with elevated privileges. Discovered by Venustech ADLab (Active-Defense Lab) researchers, the Linux kernel vulnerability (CVE-2017-15265) is due to a use-after-free memory error in the Advanced Linux Sound Architecture (ALSA) sequencer interface […]
After each major release, Apple is known to share the macOS kernel code. Apple releases a small bit of Darwin code every year, probably, because it’s based on tons of open source technologies. iOS mobile operating system is also built on the macOS foundation, and they share the common Unix-based Darwin core code. Even though you could […]
Linux kernel Long Term Support (LTS) releases are “longterm maintenance” releases that currently come with 2 years of support for the purpose backporting bug and security fixes. The usual Linux kernel releases arrive after about every 7-8 weeks. This free and open source kernel serves as the base for most of the devices, including millions […]
Update (7th September, 2017): Linux kernel developer Greg Kroah-Hartman has confirmed on his blog that Linux kernel 4.14 will be the next LTS kernel branch, which will be supported with stable kernel patch backports for at least 2 years. You can find the announcement here. Also, don’t forget to read about the best features of Linux […]
For those of you who are not interested in iOS research and would like to protect themselves against these vulnerabilities, we urge you to update your iOS device to the latest version. Without an advanced mobile security and mitigation solution on the device (such as Zimperium zIPS), there’s little chance a user would notice any malicious […]
If you search Linux kernel today and look for Linux mascot Tux on the search result page, you’ll notice something unusual. The Google card showed along with the results features a little distorted logo of Tux (Read Tux origin story here). Why is it so? Is our beloved Tux not feeling okay? Before going ahead […]
A new feature added in test snapshots for OpenBSD releases will create a unique kernel every time an OpenBSD user reboots or upgrades his computer. This feature is named KARL — Kernel Address Randomized Link — and works by relinking internal kernel files in a random order so that it generates a unique kernel binary […]
Short Bytes: After the usual development process involving seven release candidates, Linus Torvalds has released Linux kernel 4.12. Regarding commits, probably, it’s the second biggest kernel release. The most significant feature of kernel 4.12 is the support for new AMD Vega graphics processors. You can go ahead and download the Linux kernel 4.12 tarball from […]
