Title:
CONFIG_DEBUG_SG should be enabled
Status in linux package in Ubuntu:
Fix Released
Bug description:
We should enable CONFIG_DEBUG_SG to perform sanity checks when performing
operations on scatterlists. If a sanity check fails a loud warning is
printed to the logs.
This change may help in detection of an attack that relies on
scatterlist manipulation.
This config option is recommended by the Kernel Self Protection
Project[1].
