End of life / Linux Kernel / 7.3 / Still supported?

Unknown, Linux Kernel 7.3 has no published end of life date

No published date Asked and answered below, from the dates the vendor publishes. The full Linux Kernel 7.3 end of life page carries the release table and the advisory detail behind these answers.

Is Linux Kernel 7.3 still supported?

There is no answer either way. Linux Kernel publishes no end of life date for 7.3, so nothing on record says the release is supported and nothing says it has ended. An absent date is its own state and reading it as a yes would invent a support claim nobody made.

When does Linux Kernel 7.3 reach end of life?

No end of life date is published for Linux Kernel 7.3. For some technologies that absence is the vendor's own position rather than a gap in the data, so there is no date here to count down to.

Are there known CVEs that reach Linux Kernel 7.3?

3 advisories in the catalog publish an affected range that includes Linux Kernel 7.3, the most severe rated HIGH. A release matched by a count like that is matched by every fix published on its own line, so the number is a reason to take the newest build rather than a list to work through. A further 431 advisories publish no version range at all, so whether they reach it cannot be told from the advisory alone. Only the serious end is counted for this technology, so anything rated below high is outside the total.

What should I move Linux Kernel 7.3 to?

Linux Kernel 7.3 is the newest tracked Linux Kernel release, so there is nothing newer to move to.

Which Linux Kernel releases are still supported?
