SubjectRe: [bug report][stable] kernel tried to execute NX-protected page - exploit attempt? (uid: 0)
From
Date
Confirmed the following 3 upstream commits can resolve this issue:
d2a68c4effd8 x86/ftrace: Do not call function graph from dynamic trampolines
3c0dab44e227 x86/ftrace: Set trampoline pages as executable
7298e24f9042 x86/kprobes: Set instruction page as executable

And they are all included in stable 4.19.49.

Thanks,
Joseph
