CVE-2026-2436
March 26, 2026
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.
