Flatpak stack CVEs reopen the desktop sandbox trust question
A burst of bubblewrap, xdg-dbus-proxy, and Flatpak fixes shows how setup-time symlink tricks and D-Bus filter gaps still undermine the isolation users treat as a boundary.

An AI broke five of China's new crypto candidates in a day
NGCC's first round of post-quantum submissions is collapsing under human and machine cryptanalysis, and the fastest breaks came from an AI running on its own.
By staffWhen the contributor might be a model
From a Claude-found lattice break to AI-draft floods at the IETF and a bot-mediated fight on emacs-devel, free software and standards communities are arguing what counts as legitimate help, what is noise, and what threatens how work is governed.

Jim Cromie's three-patch series cuts bulk symbol attach from hundreds of milliseconds to tens, after production stalls in fleet observability tools.
By oopsStable 6.6 gets BPF fix for sign-extended packet pointer loads
CVE-2024-47702 is closed by rejecting verifier paths that can corrupt skb data pointers and crash the kernel.
By oopsOpenSSL flags high-severity DTLS heap leak and crash risk
A flawed retransmission path can send leftover buffer bytes to a peer or abort the process when a handshake write is suspended mid-message.
