Summary

linux-gcp, linux-gke, linux-raspi 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)

Duoming Zhou discovered that race conditions existed in the timer handling implementation of the Linux kernel's Rose X.25 protocol layer, resulting in use-after-free vulnerabilities. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-2318)

Roger Pau Monné discovered that the Xen virtual block driver in the Linux kernel did not properly initialize memory pages to be used for shared communication with the backend. A local attacker could use this to expose sensitive information (guest kernel memory). (CVE-2022-26365)

Roger Pau Monné discovered that the Xen paravirtualization frontend in the Linux kernel did not properly initialize memory pages to be used for shared communication with the backend. A local attacker could use this to expose sensitive information (guest kernel memory). (CVE-2022-33740)

It was discovered that the Xen paravirtualization frontend in the Linux kernel incorrectly shared unrelated data when communicating with certain backends. A local attacker could use this to cause a denial of service (guest crash) or expose sensitive information (guest kernel memory). (CVE-2022-33741, CVE-2022-33742)

Jan Beulich discovered that the Xen network device frontend driver in the Linux kernel incorrectly handled socket buffers (skb) references when communicating with certain backends. A local attacker could use this to cause a denial of service (guest crash). (CVE-2022-33743)

Oleksandr Tyshchenko discovered that the Xen paravirtualization platform in the Linux kernel on ARM platforms contained a race condition in certain situations. An attacker in a guest VM could use this to cause a denial of service in the host OS. (CVE-2022-33744)

It was discovered that the virtio RPMSG bus driver in the Linux kernel contained a double-free vulnerability in certain error conditions. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-34494, CVE-2022-34495)

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)
