Red Hat has shipped a patch for a critical use-after-free vulnerability in the Linux kernel's TCP stack, rated 9.8 out of 10, while Ubuntu has also released fixes in testing. The flaw reportedly allows a remote attacker to corrupt kernel memory with a single crafted TCP handshake, with no login, password, or user interaction required, making it remotely exploitable.
Why now: A remotely exploitable critical Linux kernel flaw requiring no authentication is a major security concern for server operators everywhere
