Welcome to the LWN.net Weekly Edition for October 12, 2023

• Remote execution in the GNOME tracker: a series of failures leads to a remotely exploitable desktop vulnerability.
• Progress on no-GIL CPython: wherein the project of removing the CPython global interpreter lock runs into one of the hardest problems in computer science.
• GCC features to help harden the kernel: compiler features that can help developers avoid bugs and vulnerabilities.
• The challenge of compiling for verified architectures: BPF is not like any other target for the compiler.
• Rethinking multi-grain timestamps: this 6.6 feature was reverted after causing user-space regressions; now developers are trying to find a better approach.

This week's edition also includes these inner pages:

• Brief items: Brief news items from throughout the community.
• Announcements: Newsletters, conferences, security updates, patches, and more.
