CVE-2024-49570 Information

Description

In the Linux kernel the following vulnerability has been resolved:

drm/xe/tracing: Fix a potential TP_printk UAF

The commit afd2627f727b ( racing: Check %s\ dereference via the field and not the TP_printk format) exposes potential UAFs in the xe_bo_move trace event.

Fix those by avoiding dereferencing the xe_mem_type_to_name[] array at TP_printk time.

Since some code refactoring has taken place explicit backporting may be needed for kernels older than 6.10.
