CVE-2026-9080
UnknownSummary
Calling `curl_easy_pause()` within the event-based `CURLMOPT_SOCKETFUNCTION` callback triggers a use-after-free vulnerability. libcurl attempts to store a flag using a dangling struct pointer immediately after that pointer's memory has been freed.
Risk Assessment
An attacker could exploit this vulnerability to achieve remote code execution or cause a denial of service in applications using libcurl, leading to compromise of confidentiality, integrity, or availability.
Recommendation
It is recommended to immediately update libcurl to a patched version. Avoid calling `curl_easy_pause()` inside the `CURLMOPT_SOCKETFUNCTION` callback until the fix is applied.
