[MAINTAINERS SUMMIT] Handling of embargoed security issues – security@korg vs. linux-distros@ (Jiri Kosina) https://lkml.kernel.org/r/nycvar.YFH.7.76.2308150927190.14207@cbobk.fhfr.pm
Yet another maintainers summit agenda proposal about security issue handling has posted. There are securitiy@korg and linux-distros@. The kernel community wants to do handling of the security fixes from only security@, without being bothered by linux-distros@. Jiri proposes to discuss about if it could eventually better handled with linux-distros@.
