A match is an indication, not proof: it is based on the software version a service reported, and fixes are often backported without changing the version. See the list

Not counted: 11 on a distribution build — the fix may be backported (openssh 8.9p1). See them

Not counted: 14 fixed by the distribution (openssh 8.9p1). See them

Not counted: 2 only affect another platform (http_server 2.4.58). See them

Vulnerabilities

Distribution build — the fix may be backported (11)

These CVEs were matched on software built by an operating-system distribution whose package revision the service does not show. Distributions often fix a flaw without changing the upstream version number, so whether this build is affected cannot be told from its version. They are not counted.

Fixed by the distribution (14)

The distribution's security data says the package revision this service shows already has the fix for these CVEs, or that its build is not affected. They are not counted.
