Details

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

scsi: qla2xxx: Fix scheduling while atomic

The driver makes a call into midlayer (fc_remote_port_delete) which can put the thread to sleep. The thread that originates the call is in interrupt context. The combination of the two trigger a crash. Schedule the call in non-interrupt context where it is more safe.
