For years, owners of Vizio smart TVs have had little control over the software running on their sets—software that can track viewing habits, push ads, and generally shape the experience of using the device.
The Software Freedom Conservancy (SFC), a US nonprofit that promotes and provides legal support for free and open source software projects, isn't happy about that—so much so that it has spent eight years trying to force the release of the complete source code for Vizio's Linux-based smart TV operating system.
Now, after numerous delays since the SFC filed suit in 2021, a California jury will decide in August whether Vizio must provide that code in executable form to SFC and any Vizio TV owner who wants it.

Linux users have been bitten by yet another vulnerability that gives containers and untrusted users the ability to gain root access, marking the second time in as many weeks that a severe threat has caught defenders off guard.
The threat, known as Dirty Frag, allows low-privilege users, including those using virtual machines, to gain root control of servers. Attacks are particularly suitable in shared environments, where a server is used by multiple parties. Hackers can also gain root as long as they have access to a separate exploit that gives a toehold into a machine. Exploit code was leaked online three days ago and works reliably across virtually all Linux distributions. Microsoft has said it has spotted signs that hackers are experimenting with Dirty Frag in the wild.
The leaked exploit is deterministic, meaning it works precisely the same way each time it’s run and across different Linux distributions. It causes no crashes, making it stealthy to run. A vulnerability known as Copy Fail, disclosed last week with no patches available to end users, possesses the same characteristics.
