The fix for the Linux kernel in Ubuntu 18.04 LTS for CVE-2019-14615 ("The Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors.") was discovered to be incomplete, meaning that in versions of the kernel before 4.15.0-91.92, an attacker could use this vulnerability to expose sensitive information.
An information disclosure flaw was found in the Linux kernel. The original fix for CVE-2019-14615 was deemed to be incomplete. The i915 graphics driver lacks control of flow for data structures which may allow a local, authenticated user to disclose information when using ioctl commands with an attached i915 device.

This provides mitigation for Gen9 hardware. 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"

Intel ID: PSIRT-TA-201910-001
CVEID: CVE-2019-14615
Intel GPU Hardware prior to Gen11 does not clear EU state
during a context switch. This can result in information
leakage between contexts.
For Gen8 and Gen9, hardware provides a mechanism for
fast cleardown of the EU state, by issuing a PIPE_CONTROL
with bit 27 set. We can use this in a context batch buffer
to explicitly cleardown the state on every context switch.
As this workaround is already in place for gen8, we can borrow
the code verbatim for Gen9.

CVE-2019-14615 kernel: Intel graphics card information leak.
A flaw was found in the kernels implementation of the i915 graphics driver where lack of control flow for data structures may allow a local authenticated user to disclose information when issuing ioctl commands to an attached i915 devices.
How it works:
1 - Userspace creates a batchbuffer
2 - Batchbuffer sent to kernel via ioctl
3 - ioctl (2) issues it as an "Execution Unit" for the hardware.
4 - The kernel schedules another process to run.
5- Another process (running as user) can access the previous Execution Unit results by re-using Execution Units results.
Affected hardware:
This flaw affects Gen7, 7.5 and Gen9 hardware only. See [1] The Intel graphics developer guides for information on how to identify your hardware to

## Abstract
Security bugs in the Linux kernel emerge endlessly and have attracted much
attention.
However, fixing security bugs in the Linux kernel could be incomplete due to
human mistakes.
Specifically, an incomplete fix fails to repair all the original security
defects in the software, fails to properly repair the original security defects,
or introduces new ones.
In this paper, we study the fixes of incomplete security bugs in the Linux
kernel for the first time, and reveal their characteristics, root causes as well
