Virtuozzo 7 : readykernel-patch (VZA-2019-078)

High Nessus Plugin ID 133460

Synopsis

The remote Virtuozzo host is missing a security update.

Description

According to the version of the vzkernel package and the readykernel-patch installed, the Virtuozzo installation on the remote host is affected by the following vulnerability :

- [3.10.0-693.21.1.vz7.46.7 to 3.10.0-957.12.2.vz7.86.2] megaraid_sas: potential kernel crash due to a NULL pointer dereference in megasas_free_cmds(). A flaw was found in 'megaraid_sas' kernel module. NULL pointer dereference can occur in megasas_free_cmds() function due incorrect error handling in megasas_alloc_cmds().
An attacker could exploit this to trigger a kernel crash.

Note that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the readykernel patch.
