Cybersecurity in the News: "Bringing back the stack attack"

According to the Project Zero team at Google, a complicated bug (CVE-2022-37454) found in the Linux kernel’s memory management (MM) subsystem can “allow a broad spectrum of uncontrolled arbitrary write primitives to achieve kernel code execution on x86 platforms.”

“While it is possible to mitigate this exploit technique from a remote context, an attacker in a local context can utilize known microarchitectural side-channels to defeat the current mitigations.”

With an average of 420 new CVEs every week, how do you cut through the noise and take action on the vulnerabilities that pose the largest threat to your device?

We launched the Timesys CVE Dashboard and update it weekly with details on the dangerous security vulnerabilities that could be affecting your device.

4-Day Crash Course

Timesys hosting the “Sick and Tired of Vulnerabilities” Embedded Linux Yocto Developer SBOM & CVE Webinar Crash Course

Next week, Timesys is excited to host a FREE 4-day crash course webinar series on how to combat false-positive CVEs, bad SBOM data, and a tedious mitigation process! Across the four days, in just 50 minutes each day, we’ll go over:

  • Different SBOM options, how you can generate them, and which methods and formats actually matter for embedded Linux devices
  • How to master the data presented in CVE listings, find all the relevant and related information, know what to look out for in the data that will mess up your process, and keep up with new CVEs
  • A three-step process for prioritizing vulnerabilities with frameworks for efficiently classifying your CVEs, and a workflow that you can use for your initial triage and ongoing maintenance as well
  • And how to leverage automation and see what kind of impact your tool choice has on your process

The 4-day crash course will begin on Tuesday, March 7th. If you miss a day, no worries! We’ll be sending daily recordings of the sessions to anyone that registers along with bonus materials.

Yocto Security: Automating compliance using OpenSCAP

How do you automate compliance using OpenSCAP (Security Content Automation Protocol) and how does this help protect your systems from vulnerabilities?

In the following blog, we provide a starting guide for SCAP on embedded/IoT Linux devices using Yocto project as an example, and review how you can scan your system for compliance, interpret SCAP content, and use pre-existing compliance checks and profiles to establish a security baseline.
