CVE-2024-38573

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: cppc_cpufreq: se corrige la posible desreferencia del puntero nulo. cppc_cpufreq_get_rate() y hisi_cppc_cpufreq_get_rate() se pueden llamar desde diferentes lugares con varios parámetros. Entonces cpufreq_cpu_get() puede devolver nulo como 'política' en algunas circunstancias. Corrija este error agregando una verificación de devolución nula. Encontrado por el Centro de verificación de Linux (linuxtesting.org) con SVACE.

A NULL pointer dereference flaw was found in cppc_cpufreq_get_rate() in the Linux kernel. This issue may result in a crash.

In the Linux kernel, the following vulnerability has been resolved: cppc_cpufreq: Fix possible null pointer dereference cppc_cpufreq_get_rate() and hisi_cppc_cpufreq_get_rate() can be called from different places with various parameters. So cpufreq_cpu_get() can return null as 'policy' in some circumstances. Fix this bug by adding null return check. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.
