The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

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.
