Ke Sun, Henrique Kawakami, Kekai Hu, Rodrigo Branco, Giorgi Maisuradze, Dan Horea Lutas, Andrei Lutas, Volodymyr Pikhur, Stephan van Schaik, Alyssa Milburn, Sebastian Österlund, Pietro Frigo, Kaveh Razavi, Herbert Bos, Cristiano Giuffrida, Moritz Lipp, Michael Schwarz, and Daniel Gruss discovered that memory previously stored in microarchitectural fill buffers of an Intel CPU core may be exposed to a malicious process that is executing on the same CPU core. A local attacker could use this to expose sensitive information. (CVE-2018-12130)

Brandon Falk, Ke Sun, Henrique Kawakami, Kekai Hu, Rodrigo Branco, Stephan van Schaik, Alyssa Milburn, Sebastian Österlund, Pietro Frigo, Kaveh Razavi, Herbert Bos, and Cristiano Giuffrida discovered that memory previously stored in microarchitectural load ports of an Intel CPU core may be exposed to a malicious process that is executing on the same CPU core. A local attacker could use this to expose sensitive information. (CVE-2018-12127)

Ke Sun, Henrique Kawakami, Kekai Hu, Rodrigo Branco, Marina Minkin, Daniel Moghimi, Moritz Lipp, Michael Schwarz, Jo Van Bulck, Daniel Genkin, Daniel Gruss, Berk Sunar, Frank Piessens, and Yuval Yarom discovered that memory previously stored in microarchitectural store buffers of an Intel CPU core may be exposed to a malicious process that is executing on the same CPU core. A local attacker could use this to expose sensitive information. (CVE-2018-12126)

Kurtis Miller discovered that a buffer overflow existed in QEMU when loading a device tree blob. A local attacker could use this to execute arbitrary code. (CVE-2018-20815)

Ke Sun, Henrique Kawakami, Kekai Hu, Rodrigo Branco, Volodrmyr Pikhur, Moritz Lipp, Michael Schwarz, Daniel Gruss, Stephan van Schaik, Alyssa Milburn, Sebastian Österlund, Pietro Frigo, Kaveh Razavi, Herbert Bos, and Cristiano Giuffrida discovered that uncacheable memory previously stored in microarchitectural buffers of an Intel CPU core may be exposed to a malicious process that is executing on the same CPU core. A local attacker could use this to expose sensitive information. (CVE-2019-11091)

It was discovered that a NULL pointer dereference existed in the sun4u power device implementation in QEMU. A local attacker could use this to cause a denial of service. This issue only affected Ubuntu 18.10 and Ubuntu 19.04. (CVE-2019-5008)

William Bowling discovered that an information leak existed in the SLiRP networking implementation of QEMU. An attacker could use this to expose sensitive information. (CVE-2019-9824)
