Descriptions

A race condition was found in the Linux Kernel. Under certain conditions, an unauthenticated attacker from an adjacent network could send an ICMPv6 router advertisement packet, causing arbitrary code execution.

Se encontró una condición de ejecución en el kernel de Linux. Bajo ciertas condiciones, un atacante no autenticado de una red adyacente podría enviar un paquete de publicidad de enrutador ICMPv6, provocando la ejecución de código arbitrario.

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Linux Kernel. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of Route Information options. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to execute code in the context of the kernel.
