CVE-2022-3061

Se ha encontrado un fallo en el Kernel de Linux en el controlador i740. El programa de espacio de usuario podía pasar cualquier valor al controlador mediante la interfaz ioctl(). El driver no comprueba el valor de "pixclock", por lo que puede causar un error de división por cero

It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the KVM VMX implementation in the Linux kernel did not properly handle indirect branch prediction isolation between L1 and L2 VMs. An attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs.
