Overview

CVE-2024-42132 is a high-severity vulnerability. It was published on July 30, 2024 and has a CVSS 3.1 base score of 7.6 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.6, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

bluetooth/hci: disallow setting handle bigger than HCI_CONN_HANDLE_MAX

Syzbot hit warning in hci_conn_del() caused by freeing handle that was

not allocated using ida allocator.

This is caused by handle bigger than HCI_CONN_HANDLE_MAX passed by

hci_le_big_sync_established_evt(), which makes code think it's unset

connection.

Add same check for handle upper bound as in hci_conn_set_handle() to

prevent warning.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
