A fix is available in the Linux kernel as indicated by the fixed commit versions. Users should update to a kernel version that includes these fixes to resolve the issue.
Description
A vulnerability in the Linux kernel's drm/gma500 driver for Oaktrail HDMI I2C reads could cause indefinite waits due to unhandled timeout and signal conditions. This issue has been fixed by returning appropriate error codes when the I2C transaction times out or is interrupted.
