What Is Attack Surface Mapping And Why It’s Critical To your Security Program

You might think an attack surface mapper is just another name for a vulnerability scanner, but they serve two very different purposes. A scanner tests the assets you already know about for specific weaknesses. An attack surface mapper answers a more fundamental question: What assets do I even hav...

What Are Attack Surface Intelligence Exposures?

Do you know every single digital asset your organization owns? For most security leaders, the honest answer is no. Between shadow IT, forgotten development servers, and complex cloud environments, your true attack surface is full of blind spots. These unknown and unmanaged assets are where...

Defeating KASLR by Doing Nothing at All

Posted by Seth Jenkins, Project Zero Introduction I've recently been researching Pixel kernel exploitation and as part of this research I found myself with an excellent arbitrary write primitive…but without a KASLR leak. As necessity is the mother of all invention, on a hunch, I started researchi...

In the Linux kernel, the following vulnerability has been resolved: powerpc/powernv/memtrace: A out-of-bounds issue in memtrace mmap has been fixed. The memtrace mmap issue involved an out-of-bounds situation. This patch addresses this issue by ensuring that the requested mapping region size...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: iommufd: Prevents ALIGN overflow. When allocating IOVA, the candidate range is aligned to the target alignment. If the range is close to ULONGMAX, the ALIGN function may wrap, resulting in a corrupted iova structure. The code use...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: s390/mm: Do not map lowcore with identity mapping. Since identity mapping is fixed at address zero, lowcore is always mapped to address zero as well. This occurs regardless of the relocatelowcore command-line option. If the optio...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: perf/core: Prevents VMA splitting of buffer mappings. The perfmmap code is careful to map the user page using mmap along with the ringbuffer and the auxiliary buffer, when the event supports this. Once the first mapping is...
