Echo: linux: security update to 6.1.170-1

medium Tenable Cloud Security Plugin ID 461669

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: wifi: radiotap: reject radiotap with
 unknown bits The radiotap parser is currently only used with the radiotap namespace (not with vendor
 namespaces), but if the undefined field 18 is used, the alignment/size is unknown as well. In this case,
 iterator->_next_ns_data isn't initialized (it's only set for skipping vendor namespaces), and syzbot
 points out that we later compare against this uninitialized value. Fix this by moving the rejection of
 unknown radiotap fields down to after the in-namespace lookup, so it will really use
 iterator->_next_ns_data only for vendor namespaces, even in case undefined fields are present.
 (CVE-2026-23367)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
