CVE-2026-68203

Resource exhaustion via vivid_init cleanup failures

Published Aug 10, 2026 · Updated Aug 10, 2026

Cleanup errors in the vivid media driver in affected Linux kernels allow attackers to cause resource leaks via unspecified vectors. vivid_init() skips platform_device_put() after a registration failure and calls platform_driver_register() instead of unregistering the driver when workqueue creation fails. The faulty paths require platform-device registration or workqueue creation to fail, limiting the reported consequence to leaked resources and system instability.
