Platform: Linux Kernel
Version: Not specified
Vulnerability: Resource Leak due to Object Reference Loop
Severity: Medium
Date: November 19, 2024 (Published), November 27, 2024 (Last Modified)
This article describes a vulnerability (CVE-2024-53084) in the Linux kernel related to the Imagination DRM driver. When resources are cleaned up during driver close, a reference loop can occur, causing outstanding VM mappings to leak. This leak happens because the PVR VM Context holds a “soft” reference to VM mappings, meaning their release relies on VM context destruction without involving reference counting.
A fix has been implemented to break the loop by freeing outstanding VM mappings before destroying the PVR Context.
What Undercode Says:
This vulnerability can potentially lead to wasted system resources. It’s crucial to update your Linux kernel to the patched version to address this issue. For specific details and remediation steps, refer to the resources provided by your Linux distribution vendor.
