Detail

In the Linux kernel, the following vulnerability has been resolved:

tracing: Fix sleeping function called from invalid context on RT kernel

When setting bootparams="trace_event=initcall:initcall_start tp_printk=1" in the cmdline, the output_printk() was called, and the spin_lock_irqsave() was called in the atomic and irq disable interrupt context suitation. On the PREEMPT_RT kernel, these locks are replaced with sleepable rt-spinlock, so the stack calltrace will be triggered. Fix it by raw_spin_lock_irqsave when PREEMPT_RT and "trace_event=initcall:initcall_start tp_printk=1" enabled.

BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:46
