CVE-2026-4271
Full vulnerability record from the local CVENow database.
Description
A flaw was found in libsoup, a library for handling HTTP requests. This vulnerability, known as a Use-After-Free, occurs in the HTTP/2 server implementation. A remote attacker can exploit this by sending specially crafted HTTP/2 requests that cause authentication failures. This can lead to the application attempting to access memory that has already been freed, potentially causing application instability or crashes, resulting in a Denial of Service (DoS).

Esta vulnerabilidad, conocida como un uso después de liberación, ocurre en la implementación del servidor HTTP/2. Un atacante remoto puede explotar esto enviando solicitudes HTTP/2 especialmente diseñadas que causan fallos de autenticación. Esto puede llevar a que la aplicación intente acceder a memoria que ya ha sido liberada, lo que podría causar inestabilidad o caídas de la aplicación, resultando en una denegación de servicio (DoS)."
