Echo: linux: security update to 6.1.153-1

medium Tenable Cloud Security Plugin ID 457118

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: s390/sclp: Fix SCCB present check
 Tracing code called by the SCLP interrupt handler contains early exits if the SCCB address associated with
 an interrupt is NULL. This check is performed after physical to virtual address translation. If the kernel
 identity mapping does not start at address zero, the resulting virtual address is never zero, so that the
 NULL checks won't work. Subsequently this may result in incorrect accesses to the first page of the
 identity mapping. Fix this by introducing a function that handles the NULL case before address
 translation. (CVE-2025-39694)

Solution

Update the linux library and its related packages to version 6.1.153-1 or later.
