CVEID: CVE-2019-14615 Summary of Vulnerability ------------------------ Insufficient control flow in certain data structures for some Intel(R) Processors with Intel Processor Graphics may allow an unauthenticated user to potentially enable information disclosure via local access Products affected: ------------------ Intel CPU’s with Gen7, Gen7.5 and Gen9 Graphics. Public Disclosure Schedule: --------------------------- Intel is pursuing a coordinated disclosure of this vulnerability. The targeted public disclosure date is January 14 2020 Mitigation Summary ------------------ This patch provides mitigation for Gen9 hardware only. Patches for Gen7 and Gen7.5 will be provided later. Note that Gen8 is not impacted due to a previously implemented workaround. The mitigation involves using an existing hardware feature to forcibly clear down all EU state at each context switch. -----BEGIN PGP SIGNATURE----- iQEcBAABAgAGBQJeGHjXAAoJEID/Kx9323OZezwH/iLlbczb6HW7AbloQVa7KRNL cZ4VHHXmMEQPSprxFuOS21/hVW1rKZzbjTGGI0qbm4qNT3LiK92E0dcoMs1Tp9Xd eElZpkeO36pqdxc/a256N3xrpmhiMnmk33F36k4qGpt6YUxvFUyZ50re0e3pO03j wGJ1cMIbAKJQmMC23yQdD44y1TH32fGeUQvwbLgktHAS/r1DxqyaZZq1hSpOiZdV TqhFLQAXUw2Cxy3FmF7KgcedcZfii1Rq5Gz7iQeyix3CbNM9r+1UGqsjGacDcXS9 /GxhBCSKf35pOj7ZxgtLPCCdL5mSAtvQO/E+yLx3F9axG9bzzNGkLpEsWeCshp8= =3jTf -----END PGP SIGNATURE----- Merge tag 'Intel-CVE-2019-14615' from bundle by Akeem Abodunrin.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
