Ubuntu Security Notice 4069-2 - USN-4069-1 fixed vulnerabilities in the Linux kernel for Ubuntu 19.04. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 19.04 for Ubuntu 18.04 LTS. It was discovered that an integer overflow existed in the Linux kernel when reference counting pages, leading to potential use-after-free issues. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

Ubuntu Security Notice 4076-1 - It was discovered that a race condition existed in the Serial Attached SCSI implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service or execute arbitrary code. It was discovered that the ext4 file system implementation in the Linux kernel did not properly zero out memory in some situations. A local attacker could use this to expose sensitive information. Various other issues were also addressed.

Ubuntu Security Notice 4068-1 - Adam Zabrocki discovered that the Intel i915 kernel mode graphics driver in the Linux kernel did not properly restrict mmap ranges in some situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition leading to a use-after-free existed in the Reliable Datagram Sockets protocol implementation in the Linux kernel. The RDS protocol is blacklisted by default in Ubuntu. If enabled, a local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
