Official Description

In the Linux kernel, the following vulnerability has been resolved:

net: qrtr: ns: Limit the maximum number of lookups

Current code does no bound checking on the number of lookups a client can

perform. Though the code restricts the lookups to local clients, there is

still a possibility of a malicious local client sending a flood of

NEW_LOOKUP messages over the same socket.

Fix this issue by limiting the maximum number of lookups to 64 globally.

Since the nameserver allows only atmost one local observer, this global

lookup count will ensure that the lookups stay within the limit.

Note that, limit of 64 is chosen based on the current platform

requirements. If requirement changes in the future, this limit can be

increased.
