CVE-2026-2436

A flaw was found in libsoup's SoupServer. A remote attacker could exploit a use-after-free vulnerability where the `soup_server_disconnect()` function frees connection objects prematurely, even if a TLS handshake is still pending. If the handshake completes after the connection object has been freed, a dangling pointer is accessed, leading to a server crash and a Denial of Service.

Se encontró un defecto en el SoupServer de libsoup. Un atacante remoto podría explotar una vulnerabilidad de uso después de liberación donde la función 'soup_server_disconnect()' libera objetos de conexión prematuramente, incluso si un handshake TLS todavía está pendiente. Si el handshake se completa después de que el objeto de conexión ha sido liberado, se accede a un puntero colgante, lo que lleva a un fallo del servidor y a una denegación de servicio.
