Detailed vulnerability description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to a race condition leading to a NULL pointer dereference in the amdisp i2c device probe path when resuming the device during probe initialization. A local user can trigger the affected probe and resume sequence to cause a denial of service.
