Echo: linux: security update to 6.1.176-1

medium Tenable Cloud Security Plugin ID 460939

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: cpsw_new: Fix potential
 unregister of netdev that has not been registered yet If an error occurs during register_netdev() for the
 first MAC in cpsw_register_ports(), even though cpsw->slaves[0].ndev is set to NULL, cpsw->slaves[1].ndev
 would remain unchanged. This could later cause cpsw_unregister_ports() to attempt unregistering the second
 MAC. To address this, add a check for ndev->reg_state before calling unregister_netdev(). With this
 change, setting cpsw->slaves[i].ndev to NULL becomes unnecessary and can be removed accordingly.
 (CVE-2026-43219)

Solution

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