In the Linux kernel, the following vulnerability has been resolved:
powercap: intel_rapl: Fix a NULL pointer dereference A NULL pointer
dereference is triggered when probing the MMIO RAPL driver on platforms
with CPU ID not listed in intel_rapl_common CPU model list. This is because
the intel_rapl_common module still probes on such platforms even if
‘defaults_msr’ is not set after commit 1488ac990ac8 (“powercap: intel_rapl:
Allow probing without CPUID match”). Thus the MMIO RAPL rp->priv->defaults
is NULL when registering to RAPL framework. Fix the problem by adding
sanity check to ensure rp->priv->rapl_defaults is always valid.
