Published Sep 11, 2024 linux CWE-667 EPSS 0.17% (7th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-45029 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 11, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

i2c: tegra: Do not mark ACPI devices as irq safe

On ACPI machines, the tegra i2c module encounters an issue due to a

mutex being called inside a spinlock. This leads to the following bug:

BUG: sleeping function called from invalid context at kernel/locking/mutex.c:585

...

Call trace:

__might_sleep

__mutex_lock_common

mutex_lock_nested

acpi_subsys_runtime_resume

rpm_resume

tegra_i2c_xfer

The problem arises because during __pm_runtime_resume(), the spinlock

&dev->power.lock is acquired before rpm_resume() is called. Later,

rpm_resume() invokes acpi_subsys_runtime_resume(), which relies on

mutexes, triggering the error.

To address this issue, devices on ACPI are now marked as not IRQ-safe,

considering the dependency of acpi_subsys_runtime_resume() on mutexes.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
