Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
stackdepot: fix stack_depot_save_flags() in NMI context<br />
<br />
Per documentation, stack_depot_save_flags() was meant to be usable from<br />
NMI context if STACK_DEPOT_FLAG_CAN_ALLOC is unset. However, it still<br />
would try to take the pool_lock in an attempt to save a stack trace in the<br />
current pool (if space is available).<br />
<br />
This could result in deadlock if an NMI is handled while pool_lock is<br />
already held. To avoid deadlock, only try to take the lock in NMI context<br />
and give up if unsuccessful.<br />
<br />
The documentation is fixed to clearly convey this.
