'A single 732-byte Python script can be used to obtain root on essentially all Linux distributions shipped since 2017': Time to update your kernel

Gaming on Linux has never been better—but that doesn't mean your distros are free from security threats. Case in point is a severe vulnerability nicknamed 'Copy Fail,' which allows a local user to dig into the guts of the OS and give themselves root privileges merely by writing four bytes of controlled data into the page cache of any readable file.

The security research team at Theori disclosed the vulnerability last Wednesday, though CISA reports that threat actors have since been observed using the exploit in the wild.
