  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/gma500: return errors from Oaktrail HDMI I2C reads\n\nxfer_read() waits for the HDMI I2C transaction to reach\nI2C_TRANSACTION_DONE, but it ignores both timeout and signal returns from\nwait_for_completion_interruptible_timeout().  If the interrupt never\nadvances the transaction state, the loop can wait forever.\n\nReturn -ETIMEDOUT when the completion wait expires, propagate interrupted\nwaits, and make the I2C master_xfer callback return the first transfer\nerror instead of reporting a successful message count.",
