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: 3 fixed by the distribution (openssh 9.2p1). See them
Not counted: 2 only affect another platform (http_server 2.4.57). See them
