Enable SLUB/SLAB allocator poisoning in zIPL
Medium Severity
To enable poisoning of SLUB/SLAB objects, check that all boot entries in
/boot/loader/entries/*.conf
have
slub_debug=P
included in its options.
To ensure that new kernels and boot entries continue to enable poisoning of SLUB/SLAB objects, add
slub_debug=P
to
/etc/kernel/cmdline
.
