  - CVE-2021-43618: Addressed an integer overflow vulnerability in the GNU Multiple Arithmetic
  Library that could lead to a buffer overflow via crafted input.

  - CVE-2022-0492: A vulnerability in the Linux kernel's cgroup_release_agent_write was addressed
  that could lead to escalation of privileges and bypass namespace isolation unexpectedly.

  - CVE-2022-0778: Addressed an issue in OpenSSL that would make it possible to trigger an infinite
  loop by crafting a certificate that has invalid elliptic curve parameters. Since certificate
  parsing takes place before the certificate signature verification process, this could lead to a
  denial-of-service attack.");
