    • This is a four part blog post series that starts with Rustproofing Linux (Part 1/4 Leaking Addresses). This post uses a simple example to demonstrate a class of vulnerability that we encounter quite frequently when auditing kernel drivers and firmware. It’s a race condition, or more precisely a TOCTOU vulnerability. The complete vulnerable C driver … Continue reading Rustproofing Linux (Part 2/4 Race Conditions) →

    • Hackers could exploit a Linux kernel bug to escape Kubernetes containers and access critical resources; however, the threat is minimized as any attacker needs to have the specific Linux capability CAP_SYS_ADMIN. The high-severity Common Vulnerabilities and Exposures (CVE) 2022-0185, first reported by security publication BleepingComputer, affects all Linux kernel versions The post Linux Kernel Bug Allows Kubernetes Container Escape appeared first on Container Journal.

    • Having been in the game of auditing kprobe-based tracers for the past couple of years, and in light of this upcoming DEF CON on eBPF tracer race conditions (which you should go watch) being given by a friend of mine from the NYU(-Poly) (OSIR)IS(IS) lab, I figured I would wax poetic on some of the … Continue reading Some Musings on Common (eBPF) Linux Tracing Bugs →
