Descriptions

A null pointer dereference flaw was found in the Linux kernel API for the cryptographic algorithm scatterwalk functionality. This issue occurs when a user constructs a malicious packet with specific socket configuration, which could allow a local user to crash the system or escalate their privileges on the system.

Este problema ocurre cuando un usuario construye un paquete malicioso con una configuración de socket específica, lo que podría permitir que un usuario local bloquee el sistema o aumente sus privilegios en el sistema.
