CVE-2018-12126

Priority
Description
Microarchitectural Store Buffer Data Sampling (MSBDS): Store buffers on some
microprocessors utilizing speculative executionmay allow an authenticated user
to potentially enable information disclosure via a side channel with local
access.
Ubuntu-Description
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.
