Echo: linux: security update to 6.1.170-1

medium Tenable Self-Hosted Container Security Plugin ID 459159

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: dlm: fix possible lkb_resource null
 dereference This patch fixes a possible null pointer dereference when this function is called from
 request_lock() as lkb->lkb_resource is not assigned yet, only after validate_lock_args() by calling
 attach_lkb(). Another issue is that a resource name could be a non printable bytearray and we cannot
 assume to be ASCII coded. The log functionality is probably never being hit when DLM is used in normal way
 and no debug logging is enabled. The null pointer dereference can only occur on a new created lkb that
 does not have the resource assigned yet, it probably never hits the null pointer dereference but we should
 be sure that other changes might not change this behaviour and we actually can hit the mentioned null
 pointer dereference. In this patch we just drop the printout of the resource name, the lkb id is enough to
 make a possible connection to a resource name if this exists. (CVE-2024-47809)

Solution

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