NVD Description

Note: Versions mentioned in the description apply only to the upstream curl-debugsource package and not the curl-debugsource package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
