Title
drm/tegra: gr2d/gr3d: Initialize address register map before HOST1X client is registered
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/tegra: gr2d/gr3d: Initialize address register map before HOST1X client is registered
The host1x_client_register() function is called just prior to register map
initialization loop, making the device available to userspace. This may
result in userspace attempting to submits a job before the register map is
initialized. Address this by moving register initialization before host1x
client registration.
Severity
No CVSS data available.
