Overview

CVE-2024-35851 is a medium-severity vulnerability. It was published on May 17, 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:

Bluetooth: qca: fix NULL-deref on non-serdev suspend

Qualcomm ROME controllers can be registered from the Bluetooth line

discipline and in this case the HCI UART serdev pointer is NULL.

Add the missing sanity check to prevent a NULL-pointer dereference when

wakeup() is called for a non-serdev controller during suspend.

Just return true for now to restore the original behaviour and address

the crash with pre-6.2 kernels, which do not have commit e9b3e5b8c657

("Bluetooth: hci_qca: only assign wakeup with serial port support") that

causes the crash to happen already at setup() time.

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.
