CVE-2025-14819

EUVD-2026-1566
When doing TLS related transfers with reused easy or multi handles and
altering the  `CURLSSLOPT_NO_PARTIALCHAIN` option, libcurl could accidentally
reuse a CA store cached in memory for which the partial chain option was
reversed. Contrary to the user's wishes and expectations. This could make
libcurl find and accept a trust chain that it otherwise would not.
