high Nessus Plugin ID 225636

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- 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. kernel: BUG: scheduling while atomic:
