70f6b3ef6f61904b7dd7be40ca921b499c89a91d16a34a7cc822f34e34e87d24Ubuntu Security Notice 4984-1 - 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. It was discovered that the Realtek RTL8188EU Wireless device driver in the Linux kernel did not properly validate ssid lengths in some situations. An attacker could use this to cause a denial of service. Various other issues were also addressed.
47d0f4a3952d8cf4b938ec83f7efd85bdb8431f9f1a68e359b4de49fcf50d2edUbuntu Security Notice 4945-2 - 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. 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. Various other issues were also addressed.

A local attacker could use this to cause a denial of service or possibly execute arbitrary code. 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. Various other issues were also addressed.

A privileged attacker could possibly use this to cause a denial of service or possibly execute arbitrary code. Olivier Benjamin, Norbert Manthey, Martin Mazein, and Jan H. Schoenherr discovered that the Xen paravirtualization backend in the Linux kernel did not properly propagate errors to frontend drivers in some situations. An attacker in a guest VM could possibly use this to cause a denial of service. Various other issues were also addressed.
