Echo: linux: security update to 6.1.158-1

medium Tenable Cloud Security Plugin ID 460077

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: net: rfkill: gpio: Fix crash due to
dereferencering uninitialized pointer Since commit 7d5e9737efda ("net: rfkill: gpio: get the name and type
from device property") rfkill_find_type() gets called with the possibly uninitialized "const char
*type_name;" local variable. On x86 systems when rfkill-gpio binds to a "BCM4752" or "LNV4752"
acpi_device, the rfkill->type is set based on the ACPI acpi_device_id: rfkill->type =
(unsigned)id->driver_data; and there is no "type" property so device_property_read_string() will fail and
leave type_name uninitialized, leading to a potential crash. rfkill_find_type() does accept a NULL
pointer, fix the potential crash by initializing type_name to NULL. Note likely sofar this has not been
caught because: 1. Not many x86 machines actually have a "BCM4752"/"LNV4752" acpi_device 2. The stack
happened to contain NULL where type_name is stored (CVE-2025-39937)

Solution

Update the linux library and its related packages to version 6.1.158-1 or later.
