Se ha encontrado una vulnerabilidad en el Kernel de Linux. Se ha declarado como problemática. Esta vulnerabilidad afecta a la función ipv6_renew_options del componente IPv6 Handler. La manipulación conlleva a una pérdida de memoria. El ataque puede ser lanzado remotamente. Es recomendado aplicar un parche para corregir este problema. Se ha asignado el identificador VDB-211021 a esta vulnerabilidad

A memory leak flaw was found in the Linux kernel’s IPv6 functionality in how a user triggers the setsockopt of the IPV6_ADDRFORM and IPV6_DSTOPTS type. This flaw allows a user to crash the system if the setsockopt function is being called simultaneously with the IPV6_ADDRFORM type and other processes with the IPV6_DSTOPTS type. This issue is unlikely to happen unless a local process triggers IPV6_ADDRFORM.
