Echo: linux: security update to 6.1.170-1

high Tenable Cloud Security Plugin ID 465338

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: scsi: ibmvfc: Fix OOB access in
 ibmvfc_discover_targets_done() A malicious or compromised VIO server can return a num_written value in the
 discover targets MAD response that exceeds max_targets. This value is stored directly in
 vhost->num_targets without validation, and is then used as the loop bound in ibmvfc_alloc_targets() to
 index into disc_buf[], which is only allocated for max_targets entries. Indices at or beyond max_targets
 access kernel memory outside the DMA-coherent allocation. The out-of-bounds data is subsequently embedded
 in Implicit Logout and PLOGI MADs that are sent back to the VIO server, leaking kernel memory. Fix by
 clamping num_written to max_targets before storing it. (CVE-2026-31464)

Solution

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