the no user namespaces line is the whole story. io_uring completes work asynchronously in kernel context, so the mitigation everyone leaned on, disabling unprivileged userns, buys nothing here. the attack surface moved and the hardening did not follow.

Wrote a PoC LPE for a tiny race condition leading to UAF. CAP_NET_ADMIN is needed for the LPE. Based on my research all major distributions using a kernel > 6.6 are vulnerable including Ubuntu 24.04. I will be reporting the bug in the upcoming days - blogpost and PoC coming later

Linux security benefits from transparency. Open source makes code available for scrutiny, allowing vulnerabilities to be identified, understood and addressed. At enterprise scale, that transparency plays an important role in how Linux security is managed. What’s new in security for Ubuntu 26.04 LTS? →

Another fun bug, we turned a Linux kernel timer UAF into a kernel read/write on Android, root + SELinux permissive. Great work ryaagard! Stay tuned for more 🦦

Linux security is built for environments where resilience matters. From vulnerability management to long-term maintenance, securing open source at enterprise scale requires a robust approach across the software lifecycle. Robustness comes from how those practices work together and hold up over time. What’s new in security for Ubuntu 26.04 LTS? →
