Descriptions

A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-free and create a situation where it may be possible to escalate privileges on the system.

Se ha encontrado un fallo en la implementación del kernel de Linux de los dispositivos TPM virtualizados proxy. En un sistema donde los dispositivos TPM virtualizados están configurados (esto no es lo predeterminado) un atacante local puede crear un uso de memoria previamente liberada y crear una situación donde puede ser posible escalar privilegios en el sistema

An update that solves 25 vulnerabilities, contains four features and has 91 fixes is now available. The SUSE Linux Enterprise 15 SP4 Azure kernel was updated to receive various security and bug fixes.
