Configure kernel to zero out memory before allocation in zIPL
Medium Severity
To ensure that the kernel is configured to zero out memory before allocation, check that all boot entries in
/boot/loader/entries/*.conf
have
init_on_alloc=1
included in its options.
To ensure that new kernels and boot entries continue to zero out memory before allocation, add
init_on_alloc=1
to
/etc/kernel/cmdline
.
