Hi,Liu Thanks your patch. What kind of environment did you test this KASLR problem ? Especialy is it kernel verssion 6.11.8-300.fc41.x86_64 ? Have you checked other versions? Additionally, do you know the version of eppic ?
Also, if possible, show this problem results when an error occurs and the results when it is correct. Please tell me.
