CVE-2024-49570: drm/xe/tracing: Fix a potential TP_printk UAF
First published: Thu Feb 27 2025(Updated: )
In the Linux kernel, the following vulnerability has been resolved: drm/xe/tracing: Fix a potential TP_printk UAF The commit afd2627f727b ("tracing: 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.
