Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the Linux kernel, specifically the arm64: acpi: Harden get cpu for acpi id() against missing CPU entry. A review discussion of the changes to support vCPU hotplug noted that there is a need to map back to the cpu and use that to index into a cpumask, requiring a valid ID. If an MPIDR check fails in acpi map gic cpu interface(), it is possible for the entry in cpu madt gicc[cpu] to be NULL, which would cause a NULL pointer dereference. Although a path to trigger this has not been established, the caller is being hardened against the possibility.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
