NVD description

In the case of the cap_net service, when a key present in the old limit was omitted from the new limit, the missing key was treated as "allow any" instead of being rejected. In certain scenarios, an application that had previously restricted a subset of network operations could ask for a new limit that extended the permissions of the process.

    Patch

    The FreeBSD project released a number of security advisories yesterday. We're still reviewing them. So far, one does not impact MidnightBSD (setcred), and two more do: CVE-2026-39461 (libcasper) and CVE-2026-45254. We've patched the latter in git on master and stable/4.0

    Post summary

    The FreeBSD project announced several advisories, identified two affecting MidnightBSD (one involving libcasper), and confirmed that a patch has been applied to the affected repository branches.
