Description:	Summary: The remote host is missing an update for the 'linux-oem-5.6' package(s) announced via the USN-4947-1 advisory. Vulnerability Insight: Kiyin (Yin Liang ) discovered that the x25 implementation in the Linux kernel contained overflows when handling addresses from user space. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-35519) It was discovered that the fastrpc driver in the Linux kernel did not prevent user space applications from sending kernel RPC messages. A local attacker could possibly use this to gain elevated privileges. (CVE-2021-28375) It was discovered that the TIPC protocol implementation in the Linux kernel did not properly validate passed encryption key sizes. A local attacker could use this to cause a denial of service (system crash). (CVE-2021-29646) It was discovered that a race condition existed in the netfilter subsystem of the Linux kernel when replacing tables. A local attacker could use this to cause a denial of service (system crash). (CVE-2021-29650) Arnd Bergmann discovered that the video4linux subsystem in the Linux kernel did not properly deallocate memory in some situations. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2021-30002) Affected Software/OS: 'linux-oem-5.6' package(s) on Ubuntu 20.04. Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
