USN-5651-1: strongSwan vulnerability Lahav Schlesinger discovered that strongSwan incorrectly handled certain OCSP URIs and and CRL distribution points (CDP) in certificates. A remote attacker could possibly use this issue to initiate IKE_SAs and send crafted certificates that contain URIs pointing to servers under their control, which can lead to a denial-of-service attack.

USN-5652-1: Linux kernel (Azure) vulnerabilities It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33655) Domingo Dirutigliano and Nicola Guerrera discovered that the netfilter subsystem in the Linux kernel did not properly handle rules that truncated packets below the packet header size. When such rules are in place, a remote attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-36946) Source: USN-5652-1: Linux kernel (Azure) vulnerabilities
