Se ha detectado un problema en el kernel de Linux versiones anteriores a 5.15.11. Se presenta una pérdida de memoria en la función __rds_conn_create() en el archivo net/rds/connection.c en una determinada combinación de circunstancias
It was discovered that the network traffic control implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Yiqi Sun and Kevin Wang discovered that the cgroups implementation in the Linux kernel did not properly restrict access to the cgroups v1 release_agent feature. A local attacker could use this to gain administrative privileges.
