CVE-2024-26975

  3. CVE-2024-26975
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.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: powercap: intel_rapl: corrige una desreferencia de puntero NULL Se activa una desreferencia de puntero NULL al probar el controlador MMIO RAPL en plataformas con ID de CPU que no figuran en la lista de modelos de CPU intel_rapl_common. Esto se debe a que el módulo intel_rapl_common aún sondea en dichas plataformas incluso si 'defaults_msr' no está configurado después de confirmar 1488ac990ac8 ("powercap: intel_rapl: Permitir sondeo sin coincidencia de CPUID"). Por lo tanto, MMIO RAPL rp->priv->defaults es NULL cuando se registra en el marco RAPL. Solucione el problema agregando una verificación de cordura para garantizar que rp->priv->rapl_defaults siempre sea válido.
