Echo: linux: security update to 6.1.176-1

high Tenable Cloud Security Plugin ID 459498

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/smc: avoid early lgr access in
 smc_clc_wait_msg A CLC decline can be received while the handshake is still in an early stage, before the
 connection has been associated with a link group. The decline handling in smc_clc_wait_msg() updates link-
 group level sync state for first-contact declines, but that state only exists after link group setup has
 completed. Guard the link-group update accordingly and keep the per-socket peer diagnosis handling
 unchanged. This preserves the existing sync_err handling for established link-group contexts and avoids
 touching link-group state before it is available. (CVE-2026-46027)

Solution

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