V4bel/Zapscape

Repository · seen by GitHub, HackerNews, Lobsters

A working exploit and write up for CVE-2026-64561, a guest to host escape in KVM on x86. The bug is a use after free in the shadow MMU, in the recursive path that runs when shadow pages are reclaimed, and a guest can trigger it alone to reach the host kernel with root privilege. It is the third in a series from the same researcher, published after the coordinated embargo ended.

Flagged 8 August 2026 · 110 → 153 stars · +39.1%
Signal

Stars 71 to 110 in a day, up 54.9%, forks 6 to 10, and Lobsters points up 44.4%. Ten forks on 110 stars this early says people are running the exploit rather than reading about it.

02Day 7

reflex-dev/xy

Repository · seen by GitHub, HackerNews, npm / PyPI

A charting library for Python, from the team behind the Reflex web framework. It renders interactive charts directly from Python objects, so the analysis and the chart live in the same place instead of the data being handed to a JavaScript layer to draw. It ships on PyPI, and that is what makes the adoption measurable: a download is someone installing it into a project, a star is someone bookmarking it, and those two numbers have been moving in opposite directions here for two weeks.

Flagged 31 July 2026 · 1,007 → 1,894 stars · +88.1%
Signal

Weekly downloads 2,668 to 4,518, up 69.3%, while stars moved 2.1%. Watchers went 3 to 10. More people are installing it than have bookmarked it, and that ratio almost never runs this way round.

03Day 3

pg83/shitty

Repository · seen by GitHub, HackerNews

A terminal emulator built for low latency and fast startup, keeping terminal state on the CPU and rendering cells through Vulkan on Linux and Metal on macOS. The README publishes head to head throughput against ghostty, alacritty and kitty with every terminal equalised first, which is unusual enough to be worth noting. The same code ships under two names for people who would rather not type the first one.

Flagged 5 August 2026 · 217 → 320 stars · +47.5%
Signal

Open issues 4 to 7, up 75%, and forks 16 to 18, against stars up 3.9%. HackerNews has stopped at 1.2%. The discussion ended and the adoption did not.

How to read this

Method

Every riser shows the earlier and latest reading. Count-based signals also show their percentage change. Rankings show the number of positions climbed from the earlier position to the latest one; a lower position is better.

Funding rounds show disclosed amounts and targets. Company rank movement shows a third-party 90-day momentum signal, current position and observation date. Archived briefings preserve each day’s published signals and follow-ups.
