Description
A flaw was found in the Linux kernel's media: stm32: dcmi driver. When the dcmi_graph_init() function fails to initialize due to issues with reset_control_assert() or reset_control_deassert(), an asynchronous notifier is not properly unregistered. This oversight can lead to resource leaks, potentially causing system instability or a denial of service (DoS) condition.
Statement
This issue affects STM32 DCMI camera on embedded platforms. Async notifier not unregistered when reset assert/deassert fails after graph init. Systems without stm32-dcmi are not affected.
