Hey guys,
recently I experience .text segment corruption in Kernel space. Could someone give some hints which can be the reason for this text segment corruption, because as we know it is read-only? Could you share what evidence did you get so you can get conclusion there happen such corruption?
IMHO, I suspect it is due RAM error...so it's not corruption coming from kernel image itself
I compared the addresses/instructions from the crash with these in vmlinux image and they were different in 1 or 2 bits. Yep, we also suspect RAM issues, but is it possible to be something other like DMA transfers?
