RSS Feeds

I'm looking for RSS feeds of vulnerabilities, ideally they'll come with severity rankings.

I currently use the following

https://www.zerodayinitiative.com/rss/
https://digital.nhs.uk/feed/cyber-alerts-feed.xml

I want feeds that give me a broad brush approach to cover as much as possible.

I'm not looking for feeds that are general news, I want technical information.
