Echo: linux: security update to 6.1.170-1

medium Tenable Self-Hosted Container Security Plugin ID 459466

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: pmdomain: bcm: bcm2835-power: Increase
 ASB control timeout The bcm2835_asb_control() function uses a tight polling loop to wait for the ASB
 bridge to acknowledge a request. During intensive workloads, this handshake intermittently fails for V3D's
 master ASB on BCM2711, resulting in "Failed to disable ASB master for v3d" errors during runtime PM
 suspend. As a consequence, the failed power-off leaves V3D in a broken state, leading to bus faults or
 system hangs on later accesses. As the timeout is insufficient in some scenarios, increase the polling
 timeout from 1us to 5us, which is still negligible in the context of a power domain transition. Also,
 replace the open-coded ktime_get_ns()/ cpu_relax() polling loop with readl_poll_timeout_atomic().
 (CVE-2026-31550)

Solution

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