Six-Year-Old Linux Kernel Flaw Lets Unprivileged Users Read Root-Owned Files

A proof-of-concept is available as ssh-keysign-pwn, taking advantage of the __ptrace_may_access() function in the Linux kernel, skipping the dumpable check when task->mm == NULL. As such, do_exit() runs exit_mm() before exit_files() (no mm, fds still there) and pidfd_getfd(2) succeeds in that window when the caller’s uid matches the target’s.

Ubuntu 25.10 Users Can Now Upgrade to Ubuntu 26.04 LTS, Here’s How

Ubuntu 26.04 LTS was released on April 23rd, 2026, but the upgrade path wasn’t open until now, not for Ubuntu 25.10 users and not for Ubuntu 24.04 LTS users. Of course, you can always force the upgrade with the update-manager -d command, but I wouldn’t recommend doing so as you might end up with a broken system.

Fragnesia Is Yet Another Local Privilege Escalation Flaw in Linux Kernel

Fragnesia (CVE-2026-46300) is a bug in the IPsec XFRM ESP-in-TCP subsystem, part of the Dirty Frag vulnerability class. It’s called Fragnesia because the skb “forgets” that a frag is shared during coalescing. The good news this time is that the mitigations for Dirty Frag also apply to Fragnesia.
