CVE-2025-38731

Kernel memory corruption via double-freed bind operations

Published Sep 5, 2025 · Updated Aug 5, 2026

Double free in the Linux kernel drm/xe driver 6.15 through 6.16.3 allows local users to corrupt kernel memory via an array-bind ioctl. When xe_vm_bind_ioctl rejects an array-bind argument, its error paths release bind_ops and later free the same allocation again because the pointer remains non-NULL. A local user must reach the Xe DRM ioctl on supported Intel graphics hardware; the resulting corruption can crash the kernel or compromise confidentiality and integrity.
