Echo: linux: security update to 6.1.176-1

medium Tenable Cloud Security Plugin ID 463960

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: netfilter: ipset: stop hash:* range
 iteration at end The following hash set variants: hash:ip,mark hash:ip,port hash:ip,port,ip
 hash:ip,port,net iterate IPv4 ranges with a 32-bit iterator. The iterator must stop once the last address
 in the requested range has been processed. Advancing it once more can move the traversal state past the
 end of the request, so a later retry may continue from an unintended position. Handle the iterator
 increment explicitly at the end of the loop and stop once the upper bound has been processed. This keeps
 the existing retry behaviour intact for valid ranges while preventing traversal from continuing past the
 original boundary. (CVE-2026-52921)

Solution

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