[$] Shielding running kernels against exploits with BPF

Cisco has some unusual challenges when it comes to deploying security patches across the company's many devices running custom kernels. John Fastabend spoke about his work preventing exploits with BPF at the 2026 Linux Storage, Filesystem, Memory-Management, and BPF Summit. The technique could substantially reduce the time necessary to respond to kernel vulnerabilities, but it will not be fully effective unless more hooks are added to the kernel.

Debian has announced the final normal update for Debian 12 ("bookworm"). Long-term-support updates will continue until 2028. As may be expected from a stable version, the update is mostly limited to security fixes. Still, it may be time for Debian users to look into upgrading to a more recent version. Conveniently, Debian 13 ("trixie") also received an update this weekend, with many of the same security fixes.

The 7.2-rc3 kernel prepatch is out for testing. Linus said: "Things continue to look normal (the 'new normal' with slightly higher rates of commits, although I do get the feeling that we're seeing that slightly balanced out by people starting to go on summer vacation)".
