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. A flaw was found in the Linux kernel's QRTR (Qualcomm IPC Router) nameserver. A malicious local client can exploit this by sending an unbounded number of NEW_LOOKUP messages. This can lead to resource exhaustion, causing a Denial of Service (DoS) for the system. The vulnerability is addressed by implementing a limit on the maximum number of lookups.
