CVE-2024-56538 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm: zynqmp_kms: Unplug DRM device before removal Prevent userspace accesses to the DRM device from causing use-after-frees by unplugging the device before we remove it. This causes any further userspace accesses to result in an error without further calls into this driver's internals.
A use-after-free vulnerability has been addressed in the Linux kernel's Direct Rendering Manager (DRM) subsystem, specifically within the ZynqMP Kernel Mode Setting (KMS) driver. This vulnerability allowed userspace accesses to the DRM device to cause use-after-free errors. The issue has been resolved by unplugging the DRM device before its removal, ensuring that any subsequent userspace accesses result in an error without interfering with the driver's internal processes. This vulnerability affects several versions of the Linux kernel.
Users can update to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for updating the kernel can be found in the official Linux kernel documentation.
