Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ptdma: pt_core_execute_cmd() should use spinlock<br />
<br />
The interrupt handler (pt_core_irq_handler()) of the ptdma<br />
driver can be called from interrupt context. The code flow<br />
in this function can lead down to pt_core_execute_cmd() which<br />
will attempt to grab a mutex, which is not appropriate in<br />
interrupt context and ultimately leads to a kernel panic.<br />
The fix here changes this mutex to a spinlock, which has<br />
been verified to resolve the issue.
