Echo: linux: security update to 6.1.135-1

medium Tenable Cloud Security Plugin ID 464707

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: i3c: Add NULL pointer check in
 i3c_master_queue_ibi() The I3C master driver may receive an IBI from a target device that has not been
 probed yet. In such cases, the master calls `i3c_master_queue_ibi()` to queue an IBI work task, leading to
 "Unable to handle kernel read from unreadable memory" and resulting in a kernel panic. Typical IBI
 handling flow: 1. The I3C master scans target devices and probes their respective drivers. 2. The target
 device driver calls `i3c_device_request_ibi()` to enable IBI and assigns `dev->ibi = ibi`. 3. The I3C
 master receives an IBI from the target device and calls `i3c_master_queue_ibi()` to queue the target
 device driver’s IBI handler task. However, since target device events are asynchronous to the I3C probe
 sequence, step 3 may occur before step 2, causing `dev->ibi` to be `NULL`, leading to a kernel panic. Add
 a NULL pointer check in `i3c_master_queue_ibi()` to prevent accessing an uninitialized `dev->ibi`,
 ensuring stability. (CVE-2025-23147)

Solution

Update the linux library and its related packages to version 6.1.135-1 or later.
