Description
A flaw was found in the Linux kernel. A local user could experience a denial of service (DoS) if a system crash occurs very early in the boot process. This is because trace_printk() events, which are crucial for debugging, are not registered early enough. This timing issue results in unreadable trace output, hindering critical system analysis and debugging efforts.
