Description

This security bulletin contains information about 1 vulnerability.


1) Use-after-free (CVE-ID: CVE-2026-10536)

CWE-ID: CWE-416 - Use After Free

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to use-after-free in libcurl HTTP/2 stream-dependency handling when resetting and cleaning up an easy handle configured with HTTP/2 stream dependencies. A local user can invoke curl_easy_reset() and then curl_easy_cleanup() on such a handle to cause a denial of service.

The issue only affects libcurl and requires use of the rarely used HTTP/2 stream-dependency options CURLOPT_STREAM_DEPENDS or CURLOPT_STREAM_DEPENDS_E.
