Overview

CVE-2024-38780 is a medium-severity vulnerability. It was published on June 21, 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:

dma-buf/sw-sync: don't enable IRQ from sync_print_obj()

Since commit a6aa8fca4d79 ("dma-buf/sw-sync: Reduce irqsave/irqrestore from

known context") by error replaced spin_unlock_irqrestore() with

spin_unlock_irq() for both sync_debugfs_show() and sync_print_obj() despite

sync_print_obj() is called from sync_debugfs_show(), lockdep complains

inconsistent lock state warning.

Use plain spin_{lock,unlock}() for sync_print_obj(), for

sync_debugfs_show() is already using spin_{lock,unlock}_irq().

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.
