Good post about exploiting the Wi-Fi stack in a Tesla Model S (2020). First exploits the Wi-Fi firmware, then the host. Firmware vulnerability is the 802.11e (WMM) functionality when handling ADDTS and TSPEC frames, host vulnerability in the driver.

A memcpy will copy all bytes except the header. The number of bytes to be copied is calculated as "to_copy = length - 4". But when the packet has no or an incomplete header, this calculation overflows, leading to a heap overflow.

I LOVE Vaporwave

I wrote a flash cards app with some highly opinionated design choices:

It's very performance focused and has no noticeable latency even with thousands of cards, due to using segment trees.

The cards are stored in an SQLite database so you can edit them with your favorite DB GUI or the sqlite3 CLI.

It's written in C because why not.

You can find the code here: https://git.exozy.me/a/SDC

Hi! I'm a Game Developer / Designer & Pixel-Artist. #Introduction
I use MsPaint for PixelArt and Unreal Engine for games.

Working on Unreal Racing: https://linktr.ee/UnrealRacing

Fun fact, not: In C, it's difficult to evaluate an expression in 8 bits. Integer promotion implicitly converts almost everything to int. Such as...

void f(uint8_t prev, uint8_t next) { if (next == (uint8_t) (prev + 1)) { /* cast needed to avoid promotion to int */ } }

I've been hanging out on here for a while now and have yet to do a proper #introduction. So here it goes.

👋 Hi there. I'm Jeff. I live in #Pittsburgh with my wife, two kids and #dog Buddy.

I work for REI Co-Op where I lead #ProductManagement for retail employee tools. I love working each day to help ensure the outdoors is accessible to all!

I also spend a lot of time outside, either #ultrarunning, #cycling or #skiing I look forward to connecting with other outdoor enthusiasts on Mastodon!

Hi folks, I really enjoy Mastodon. It does remind me of the olden days of #irc and the #BBS era (in a good way).

I teach computer engineering technology at the University of Kentucky. I'm originally from #Germany.

I have nine years of experience working in Alt Media for educational access, and I have a little advice, particularly for furry artists on how to write Alt Text that will be useful and accessible for your blind followers.
A summary list:

1. Be brief as possible.
2. Do not repeat information.
3. Choose to describe what is most important.
4. Do not use it to circumvent the system.

Waving hello...
By way of #introduction #introductions (If I get the concept of hashtags right):
Physically: living in the US midwest ;
Mentally: occupying as much of the interesting parts of the internet as I can.
I grew up reading mostly SF and science books, so I've seen myriad futures before, just not this particular one.
Interests: Learning, gardening, random and unofficial tutoring, STEM, archaeology, and whatever any of you might introduce me to.
What I'm hoping to find here: civil and engaging conversations

Forbes really knocks it out of the park with their business prowess

So, i'm gonna give #qt and real good try over #gtk. The only exception is i'm still gonna use #webkit2gtk browsers. This is mostly due to #lxqt being mature enough now lol

We did it!!! Our little all-assembly risc-v os can run Doom!
