    Map the amount of fixes with "... improved bounds checking...", "...improved memory handling...", "...improved memory management..." into the amount of developer, QA and release management teams salaries per hour, versus other stuff they could be working on, and that gives an approximate value of how using specific languages maps into monetary loss, and why companies are starting to care nowadays, given computers are always exposed to the world network.

      You need also factor development time and ease of finding developers willing to work in a specific language. There are other factors like readability of the code (very verbose languages are likely to be worse) and cost of maintenance - languages forcing a lot of abstractions are likely much worse.

    Lots of "in collaboration with Claude and Anthropic Research" mentions, no mentions of other labs. I'd assume Apple already had access to whatever the most powerful model is at the various US-based labs, but perhaps not?

      Apple isn’t friends with OpenAI anymore

      Apple also hosts a copy of Claude internally in their servers.

        Do they? As in Claude but on premises? Wonder if this is gonna be the solution that e.g. banks will require, exactly like they do now for cloud services (e.g. Azure on premises).

          Pretty extreme solution… you can get Claude models from AWS Bedrock and Google Model Zoo. These are both very helpful for compliance and security, but do require you to have a cloud strategy.

    Collision counts are absurd. CVE-2026-43739 has roughly twenty credited researchers; CVE-2026-43816 has nearly as many. And ai attribution getting credit.

      One CVE even lists the same person twice!

      CVE-2026-64691: Ruslan Dautov, Ruslan Dautov

      • proactivesvcs 1 hour ago
        One of them lists an anonymous person!

        CVE-2026-43744: Mathis Mansière, an anonymous researcher

        • nkrisc 58 minutes ago
          It reads as if "an anonymous researcher" is describing Mathis Mansière, which is quite humorous.

            Genius, that made my day!

            Spell checker fixed a typo, it was originally "an Anonymous researcher" /s

          It's Ted Danson.

    Weird thing to see at number 3 on HN - is there some subtle context I am missing here?

    Are we wink winking that it's a lot of fixes?

      Relevant context might be for example that there are 4 mentions each of Claude by Anthropic and XGPT by ThreatBook, both based on LLMs.

      AI attribution might be one reason people are particularly curious.

      And it's not actually that much information "about the security content". For example: "Impact: An app may be able to access sensitive user data. Description: An access issue was addressed with additional sandbox restrictions." This references CVE-2026-43819, which doesn't have any more information. Compare this with the nearly decade-old https://support.apple.com/en-gb/103680, and you see much more specific information about problems and their remedies (except in situations where Apple's action was to update a vendor component).

      I think it's because it's the first big batch of fixes found at Apple by Mythos.

      I think that's it?
