Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified) openSUSE Tumbleweed versions prior to kernel-devel-7.0.11-1.1

Description The nameserver in the Qualcomm Router (qrtr) network subsystem does not limit the number of nodes it handles. A malicious client could register a large number of random nodes, resulting in memory exhaustion, which is a state where the system consumes all available RAM and becomes unresponsive.
