CVE-2026-2443
Full vulnerability record from the local CVENow database.
Description
A flaw was identified in libsoup, a widely used HTTP library in GNOME-based systems. When processing specially crafted HTTP Range headers, the library may improperly validate requested byte ranges. In certain build configurations, this could allow a remote attacker to access portions of server memory beyond the intended response. Exploitation requires a vulnerable configuration and access to a server using the embedded SoupServer component.

"value": "Se identificó una vulnerabilidad en libsoup, una librería HTTP ampliamente utilizada en sistemas basados en GNOME. Al procesar encabezados HTTP Range especialmente diseñados, la librería podría validar incorrectamente los rangos de bytes solicitados. En ciertas configuraciones de compilación, esto podría permitir a un atacante remoto acceder a porciones de la memoria del servidor más allá de la respuesta prevista. La explotación requiere una configuración vulnerable y acceso a un servidor que utilice el componente SoupServer incrustado."
