Ubuntu Security Notice 5337-1 - It was discovered that the BPF verifier in the Linux kernel did not properly restrict pointer types in certain situations. 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.
