CVE-2026-10536

A use-after-free vulnerability exists in libcurl when an application

configures an HTTP/2 stream-dependency tree via `CURLOPT_STREAM_DEPENDS` or

`CURLOPT_STREAM_DEPENDS_E`, subsequently invokes `curl_easy_reset()`, and

finally terminates the handle with `curl_easy_cleanup()`. During this final

cleanup phase, libcurl attempts to access and modify an internal structure

that was already freed during the reset operation.
