CVE Details

Release Date:

2024-05-01

Description

In the Linux kernel, the following vulnerability has been resolved:\npowercap: intel_rapl: Fix a NULL pointer dereference\nA NULL pointer dereference is triggered when probing the MMIO RAPL\ndriver on platforms with CPU ID not listed in intel_rapl_common CPU\nmodel list.\nThis is because the intel_rapl_common module still probes on such\nplatforms even if 'defaults_msr' is not set after commit 1488ac990ac8\n('powercap: intel_rapl: Allow probing without CPUID match'). Thus the\nMMIO RAPL rp->priv->defaults is NULL when registering to RAPL framework.\nFix the problem by adding sanity check to ensure rp->priv->rapl_defaults\nis always valid.
