CVE-2023-6915

Se encontró un problema de desreferencia de puntero null en ida_free en lib/idr.c en el kernel de Linux. Este problema puede permitir que un atacante que utilice esta librería cause un problema de denegación de servicio debido a una verificación faltante en el retorno de una función.

Wei Chen discovered that a race condition existed in the TIPC protocol implementation in the Linux kernel, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service. It was discovered that the virtio network implementation in the Linux kernel did not properly handle file references in the host, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly expose sensitive information.
