    Published: 21 Sept 2022Last Modified: 14 Sept 2026

    Summary: linux, linux-aws, linux-aws-hwe, linux-azure-4.15, linux-dell300x, linux-gcp, linux-gcp-4.15, lnux-hwe, inux-kvm, linux-oracle, linux-raspi2, linux-snapdragon vulnerabilities

    Details: 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)
