USN-4945-2: Linux kernel (Raspberry Pi) vulnerabilities USN-4945-1 fixed vulnerabilities in the Linux kernel for Ubuntu 20.04 LTS and Ubuntu 18.04 LTS. This update provides the corresponding Linux kernel updates targeted specifically for Raspberry Pi devices in those same Ubuntu Releases. Original advisory details: It was discovered that the Nouveau GPU driver in the Linux kernel did not properly handle error conditions in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-25639) Jan Beulich discovered that the Xen netback backend in the Linux kernel did not properly handle certain error conditions under paravirtualization. An attacker in a guest VM could possibly use this to cause a denial of service (host domain crash). (CVE-2021-28038) It was discovered that the fastrpc driver in the Linux kernel did not prevent user space applications from sending kernel [ more… ]
