Summary

linux-hwe, linux-aws-5.3, linux-gke-5.3, linux-raspi2-5.3 vulnerability

Details

It was discovered that the cgroup v2 subsystem in the Linux kernel did not properly perform reference counting in some situations, leading to a NULL pointer dereference. A local attacker could use this to cause a denial of service or possibly gain administrative privileges.
