Severity
Important
Scope
1 vulnerability in this advisory, including CVE-2026-92392.
CVE-2026-92392
A flaw was found in curl. When curl uploads data over an HTTP/2 connection, it mishandles server stream reset frames, which can lead to the reuse of previously released memory. Under specific memory and timing conditions, a malicious server can exploit this flaw to execute arbitrary code on the client system or cause the application to crash, resulting in a Denial of Service (DoS).
8.1 (High)

CVE-2026-92392
A flaw was found in curl. When curl uploads data over an HTTP/2 connection, it mishandles server stream reset frames, which can lead to the reuse of previously released memory. Under specific memory and timing conditions, a malicious server can exploit this flaw to execute arbitrary code on the client system or cause the application to crash, resulting in a Denial of Service (DoS).
