A flaw was found in the Linux kernel. An out-of-bounds read was discovered in the libiscsi module that could lead to reading kernel memory or a crash. The highest threat from this vulnerability is to data confidentiality as well as system availability.
The LIBISCSI module will be auto-loaded when required, its use can be disabled by preventing the module from loading with the following instructions:
The system will need to be restarted if the libiscsi modules are loaded. In most circumstances, the libiscsi kernel modules will be unable to be unloaded while any network interfaces are active and the protocol is in use.
If the system requires iscsi to work correctly, this mitigation may not be suitable.
