A race condition vulnerability in the Linux kernel's drm/xe virtual memory management was resolved. The issue involved premature destruction of page tables (PTs) before contested VMAs (virtual memory areas) were unlinked, leading to a NULL pointer dereference when concurrent threads accessed shared buffer objects. This could cause kernel crashes due to dereferencing a NULL pointer in xe_pt_zap_ptes(). The fix defers destruction of PTs until after all contested VMAs are safely unlinked and destroyed.
