Discover the latest trends and insights on public software development activity on GitHub with the release of Q4 2023 data for the Innovation Graph.

In this post, I’ll look at CVE-2023-6241, a vulnerability in the Arm Mali GPU that allows a malicious app to gain arbitrary kernel code execution and root on an Android phone. I’ll show how this vulnerability can be exploited even when Memory Tagging Extension (MTE), a powerful mitigation, is enabled on the device.

Enterprise Managed Users can now enable secret scanning on their user namespace repositories. Owners of user repositories will receive secret scanning alerts when a supported secret is detected in their…

Get excited for this month’s Release Radar. Maintainers were hard at work this past month, shipping major updates for you all. Read on for our top staff picks.

Using CVE-2023-43641 as an example, I’ll explain how to develop an exploit for a memory corruption vulnerability on Linux. The exploit has to bypass several mitigations to achieve code execution.

Users who are not part of the mandatory 2FA program will now be added to it within 24 hours of creating their first release. In August we expanded the 2FA…

In this post, I’ll exploit CVE-2023-4069, a type confusion in Chrome that allows remote code execution (RCE) in the renderer sandbox of Chrome by a single visit to a malicious site.

CVE-2023-43641 is a vulnerability in libcue, which can lead to code execution by downloading a file on GNOME.

In this post, I’ll exploit CVE-2023-3420, a type confusion in Chrome that allows remote code execution (RCE) in the renderer sandbox of Chrome by a single visit to a malicious site.

GitHub Advanced Security customers can now perform on-demand validity checks for supported partner patterns, and the alert index view now shows if a secret is active. This builds on our…

A look at how we improved the readability of code on GitHub.

SELinux is the most popular Linux Security Module used to isolate and protect system components from one another. Learn about different access control systems and Linux security as I introduce the foundations of a popular type system.

The new GitHub Code View brings users many new features to improve the code reading and exploration experiences, and we overcame a number of unique technical hurdles in order to deliver those features without compromising performance.

In this blog, I’ll look at CVE-2022-46395, a variant of CVE-2022-36449 (Project Zero issue 2327), and use it to gain arbitrary kernel code execution and root privileges from the untrusted app domain on an Android phone that uses the Arm Mali GPU. I’ll also explain how root cause analysis of CVE-2022-36449 led to the discovery of CVE-2022-46395.

Design can have a significant impact on delivering accessible experiences to our users. It takes a cultural shift, dedicated experts, and permission to make progress over perfection in order to build momentum. We’ve got a long way to go, but we’re starting to see a real shift in our journey to make GitHub a true home for all developers.

Learn some tips, tricks, and tools for mastering the command line from GitHub’s own developers.

How to verifiably link npm packages to their source repository and build instructions.

Explore how creating a great developer experience can help provide a more inclusive financial services environment.

In this post, I’ll look at a security-related change in version r40p0 of the Arm Mali driver that was AWOL in the January update of the Pixel bulletin, where other patches from r40p0 was applied, and how these two lines of changes can be exploited to gain arbitrary kernel code execution and root from a malicious app. This highlights how treacherous it can be when backporting security changes.

CVE-2022-25664, a vulnerability in the Qualcomm Adreno GPU, can be used to leak large amounts of information to a malicious Android application. Learn more about how the vulnerability can be used to leak information in both the user space and kernel space level of pages, and how the GitHub Security Lab used the kernel space information leak to construct a KASLR bypass.

Our mission to accelerate human progress through developer collaboration requires us, from time to time, to fight against legal developments that would needlessly impair developers’ right to innovate. That’s why GitHub has filed an amicus brief in the appeal of Yout LLC v. Recording Industry of America, Inc.
