Description

powercap: intel_rapl: Fix a NULL pointer dereference

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.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
