- Summary
- powercap: intel_rapl: Fix a NULL pointer dereference
- Details
-
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 intelraplcommon CPU model list.
This is because the intelraplcommon module still probes on such platforms even if 'defaultsmsr' is not set after commit 1488ac990ac8 ("powercap: intelrapl: 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.
