Ubuntu and RHEL lack fixes for a Linux TCP use-after-free that Anthropic says it exploited to run commands as root on MPTCP servers.

    The score sounds a bit overblown considering this is for MPTCP which is as far as I understand rarely used? And it sounds like the chance of this leading to anything more than a crash is low. But whatever.

    It’s a data race. Memory safety is still super important for security.

      Every Go application since 1.24 will activate MPTCP on their sockets by default, so it’s in fact quite widely used.

      Many orgs consider the rating overblown. While the impact is devastating, the attack is hard to pull of.

      They’re able to issue shell commands as root.
