Echo: linux: security update to 6.1.164-1

high Tenable Cloud Security Plugin ID 461179

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: dpaa2-switch: add bounds check for
 if_id in IRQ handler The IRQ handler extracts if_id from the upper 16 bits of the hardware status register
 and uses it to index into ethsw->ports[] without validation. Since if_id can be any 16-bit value (0-65535)
 but the ports array is only allocated with sw_attr.num_ifs elements, this can lead to an out-of-bounds
 read potentially. Add a bounds check before accessing the array, consistent with the existing validation
 in dpaa2_switch_rx(). (CVE-2026-23180)

Solution

Update the linux library and its related packages to version 6.1.164-1 or later.
