Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 460151

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: ksmbd: validate EaNameLength in
 smb2_get_ea() smb2_get_ea() reads ea_req->EaNameLength from the client request and passes it directly to
 strncmp() as the comparison length without verifying that the length of the name really is the size of the
 input buffer received. Fix this up by properly checking the size of the name based on the value received
 and the overall size of the request, to prevent a later strncmp() call to use the length as a "trusted"
 size of the buffer. Without this check, uninitialized heap values might be slowly leaked to the client.
 (CVE-2026-31612)

Solution

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