The comment thread discusses an open-source hardware project related to the Gravis Ultrasound sound card, focusing on sourcing difficulties for a required chip and opinions about its value. There is uncertainty regarding the functionality of the board design due to lack of testing.
- Board design relies on a difficult-to-source obsolete chip
Counterarguments:
- This is open-source hardware, caveat emptor is implied
- At this stage in a project like this, I’d expect the people who were getting boards fabbed to also have the skills to sanity check the schematics and layout before they sent the gerbers off to China

GhostLock is a critical vulnerability in the Linux kernel that has existed since 2011, allowing unprivileged local attackers to escalate privileges and escape containers. The exploit strategy involves triggering a race condition with a specific sequence of futex operations, leading to a stack-use-after-free (UAF) scenario.
This vulnerability could lead to significant security breaches in systems relying on Linux, potentially compromising sensitive data or enabling unauthorized access.
- 15-year existence in Linux distributions
- No special kernel configuration or privilege required
- $92,337 reward from Google's kernelCTF
