Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved by adding shadow buffering for deferred I/O in the drm/fbdev-dma module. This change addresses driver errors related to kernel NULL pointer dereferences and paging requests. The patch modifies the drm fbdev dma driver fbdev probe() function to allocate a shadow buffer for drivers requiring deferred I/O, ensuring that DMA areas are properly handled. The use of deferred I/O without a shadow buffer is no longer possible.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
