From this webpage screenshot, the following key information about the vulnerability can be obtained: Issue Description: During startup, a null pointer dereference occurs in the function. This is related to the incomplete probing of the regulator driver ( still being NULL). Debugging Information: By adding additional statements in the code, the root cause was confirmed. Using a JTAG debugger, it was observed that and may be executed by different kernel threads. Solution: To enforce synchronous probing, the function of the regulator driver was modified to execute synchronously, thus avoiding null pointer dereferences caused by asynchronous probing.
