CVE-2025-21976

CVE-2025-21976 affects the Linux kernel fbdev/hyperv_fb driver. Unbinding a Hyper‑V framebuffer can trigger framebuffer_release while the framebuffer is in use, causing a WARN and potential failure to release resources. The fix moves framebuffer and memory release to fb_ops.fb_destroy for gracefu...
