Descriptions

Insufficient access control in the Linux kernel driver for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

Un control de acceso insuficiente en el controlador del kernel de Linux para algunos Intel® Processors, puede habilitar a un usuario autenticado para permitir potencialmente una divulgación de información por medio de un acceso local

Simon Scannell discovered that the bpf verifier in the Linux kernel did not properly calculate register bounds for certain operations. A local attacker could use this to expose sensitive information or gain administrative privileges. Moritz Lipp, Michael Schwarz, Andreas Kogler, David Oswald, Catherine Easdon, Claudio Canella, and Daniel Gruss discovered that the Intel Running Average Power Limit driver in the Linux kernel did not properly restrict access to power data. A local attacker could possibly use this to expose sensitive information. Various other issues were also addressed.
