Title
drm/xe/dma-buf: fix UAF with retry loop
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/xe/dma-buf: fix UAF with retry loop Retry doesn't work here, since bo will be freed on error, leading to UAF. However, now that we do the alloc & init before the attach, we can now combine this as one unit and have the init do the alloc for us. This should make the retry safe. Reported by Sashiko. v2: Fix up the error unwind (CI) (cherry picked from commit 479669418253e0f27f8cf5db01a731352ea592e7)

This is a local syscall/ioctl path, not a network, adjacent, or physical attack surface.\nAC:L - The UAF arises from attacker-triggerable retry/error handling in the dma-buf import path; a local attacker can repeatedly import dma-bufs and create contention/pressure to exercise the retry loop. No condition appears to require an uncontrollable victim action or rare external state.\nPR:L - The ioctl is DRM_RENDER_ALLOW and Xe supports render nodes, with no CAP_SYS_ADMIN, DRM master, or authentication gate in the path. The attacker needs only local access to the DRM render device and a dma-buf FD, so this is low privilege.\nUI:N - No victim user action is required once the attacker has local access to the device node. The attacker can invoke the ioctl and drive the relevant dma-buf operations directly.\nS:U - The bug corrupts kernel DRM/Xe memory from within the same kernel security authority. It does not inherently cross a VM, IOMMU, or other separate security scope boundary.\nC:H - This is a kernel heap use-after-free involving a freed xe_bo/GEM object that can later be reused through cleanup or dma-buf move-notify paths. Such UAF memory corruption is defensibly capable of producing kernel memory disclosure.\nI:H - The stale xe_bo/GEM pointer can be used after free in object/refcount and move-notify handling, giving a plausible kernel heap corruption primitive. Under the requested scoring rule, this supports arbitrary modification or code execution impact.\nA:H - Even without full exploitation, the UAF can dereference or operate on freed/corrupted kernel objects and crash the kernel. Related Xe dma-buf fixes reported NULL dereferences and crashes in similar paths."
