Summary
A vulnerability has been identified in the Linux kernel that allows for unlimited node registration by the nameserver. This can lead to memory exhaustion if a malicious client starts registering random nodes.
Risk Assessment
The organization may be exposed to attacks that lead to resource exhaustion, potentially resulting in system crashes or performance degradation.
Recommendation
It is recommended to update the Linux kernel to the version that implements a limit of 64 nodes to minimize the risk of memory exhaustion.
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: net: qrtr: ns: Limit the total number of nodes Currently, the nameserver doesn't limit the number of nodes it handles. This can be an attack vector if a malicious client starts registering random nodes, leading to memory exhaustion. Hence, limit the maximum number of nodes to 64. Note that, limit of 64 is chosen based on the current platform requirements. If requirement changes in the future, this limit can be increased.
