CVE-2025-21995

In the Linux kernel, the following vulnerability has been resolved: drm/sched: Fix fence reference count leak The last_scheduled fence leaks when an entity is being killed and adding the cleanup callback fails. Decrement the reference count of prev when dma_fence_add_callback() fails, ensuring proper balance. [phasta: add git tag info for stable kernel]
