The vulnerability was introduced in 581cf22 [1] as mentioned in the
commit fixing the vulnerability (78f5814) [2]. It reads:
Stream: fixed client certificate validation with OCSP.
Check for OCSP status was missed in 581cf22, resulting
in a broken validation.
581cf22 is the one introducing "client certificate validation with OCSP"
and the ssl_ocsp directive mentioned in the F5 advisory [3].
The patch was cherry-picked for trixie and bookworm via p-u, the patch
seems harmless but it does not fix the vulnerability because it does not
exist on versions older than 1.27.2, so it marks trixie, bookworm and
bullseye as not-affected.

nginx 1.22.1-9+deb12u7 (bookworm) [1] and 1.26.3-3+deb13u5 (trixie) [2]
included a patch that was a regression commit (39d7d0b) [3] for the fix of
CVE-2026-42946, but they did not include the fix itself (baef7fd) [4].
