Corrupt characters in Xorg.0.log
Opening Xorg.0.log my editor reports corrupted characters There is a vulnerability risk, as xorg is not checking the data is valid, could become a more serious risk, if they connect an HDMI device with invalid characters, that somehow is made into an overflow RCE
X.Org version: 1.21.1.7

The 0x81 in the middle, is corrupt
Could xorg filter messages, to check they contain only valid characters? I appreciate that it is probably coming from the monitor,
