Vulnerability Details : CVE-2019-9112
The msm gpu driver for custom Linux kernels on the Xiaomi perseus-p-oss MIX 3 device through 2018-11-26 has an integer overflow and OOPS because of missing checks of the count argument in _sde_debugfs_conn_cmd_tx_write in drivers/gpu/drm/msm/sde/sde_connector.c. This is exploitable for a device crash via a syscall by a crafted application on a rooted device.

CWE ids for CVE-2019-9112
-
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.Assigned by: nvd@nist.gov (Primary)
