CVE-2026-2436
MEDIUMLibsoup: libsoup: denial of service via use-after-free in soupserver during tls handshake
Title source: cnaDescription
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.
