Echo: linux: security update to 6.1.176-1

medium Tenable Cloud Security Plugin ID 464748

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
 (CVE-2026-46026)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
