CVE-2018-3693 – Kernel: speculative bounds check bypass store
https://notcve.org/view.php?id=CVE-2018-3693
Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis. Los sistemas con microprocesadores que emplean la ejecución especulativa y la predicción de ramas podría permitir la divulgación no autorizada de información a un atacante con acceso de usuario local mediante un desbordamiento de búfer especulativo y el análisis de canal lateral. An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an address which depends on the untrusted value. Such writes cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). • https://access.redhat.com/errata/RHSA-2018:2384 https://access.redhat.com/errata/RHSA-2018:2390 https://access.redhat.com/errata/RHSA-2018:2395 https://access.redhat.com/errata/RHSA-2019:1946 https://access.redhat.com/errata/RHSA-2020:0174 https://cdrdv2.intel.com/v1/dl/getContent/685359 https://help.ecostruxureit.com/display/public/UADCE725/Security+fixes+in+StruxureWare+Data+Center+Expert+v7.6.0 https://security.netapp.com/advisory/ntap-20180823-0001 https://www.oracle.com/s • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
