CVE-2024-24859 · Severity: medium · CVSS 4.6 · Published 2024-02-05

A synchronization issue exists in the Bluetooth component of the Linux kernel. This flaw could allow an attacker with high-level access to disrupt Bluetooth services, potentially causing a system crash or service outage. This affects various Linux-based systems, including industrial automation hardware like Siemens SIMATIC controllers.

Technologies: [Linux Kernel](https://junglewise.ai/threats/technologies/kernel), [Siemens SIMATIC S7-1500 TM MFP](https://junglewise.ai/threats/technologies/simatic-s7-1500-tm-mfp). Vendors: [Linux](https://junglewise.ai/threats/vendors/linux), [Siemens](https://junglewise.ai/threats/vendors/siemens).

## Quick answers

**How severe is CVE-2024-24859?** Medium severity, with a CVSS score of 4.6, published 5 February 2024.

**Which products and versions are affected?** Linux Kernel up to 3.19.8, 6.0 to 6.7.2, 6.8-rc1; Siemens SIMATIC S7-1500 TM MFP All versions using affected GNU/Linux subsystem.

**Is there a fix for CVE-2024-24859?** No fixed version is recorded yet. Check the vendor's advisory in the references below. If you run it, Junglewise drafts a mitigation that fits your setup and applies it once you approve, with senior security engineers behind it.

**How is CVE-2024-24859 attacked?** It is attacked from the adjacent network, in an operating system.

**Am I affected by CVE-2024-24859?** Check whether you run Linux Kernel or Siemens SIMATIC S7-1500 TM MFP at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## Technical details

A race condition was identified in the net/bluetooth component of the Linux kernel, specifically within the sniff_min_interval_set() and sniff_max_interval_set() functions. The vulnerability stems from improper synchronization during concurrent execution when setting Bluetooth sniff intervals. An attacker with high privileges and adjacent network access could exploit this race condition to trigger a 'sniffing exception,' leading to a denial of service (DoS). The issue affects kernel versions up to 3.19.8 and the 6.x branch up to 6.7.2. Siemens has also confirmed impact on the GNU/Linux subsystem of SIMATIC S7-1500 TM MFP devices.

## Affected products

- Linux Linux Kernel up to 3.19.8, 6.0 to 6.7.2, 6.8-rc1
- Siemens SIMATIC S7-1500 TM MFP All versions using affected GNU/Linux subsystem
