Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
virtio_console: eliminate anonymous module_init & module_exit<br />
<br />
Eliminate anonymous module_init() and module_exit(), which can lead to<br />
confusion or ambiguity when reading System.map, crashes/oops/bugs,<br />
or an initcall_debug log.<br />
<br />
Give each of these init and exit functions unique driver-specific<br />
names to eliminate the anonymous names.<br />
<br />
Example 1: (System.map)<br />
ffffffff832fc78c t init<br />
ffffffff832fc79e t init<br />
ffffffff832fc8f8 t init<br />
<br />
Example 2: (initcall_debug log)<br />
calling init+0x0/0x12 @ 1<br />
initcall init+0x0/0x12 returned 0 after 15 usecs<br />
calling init+0x0/0x60 @ 1<br />
initcall init+0x0/0x60 returned 0 after 2 usecs<br />
calling init+0x0/0x9a @ 1<br />
initcall init+0x0/0x9a returned 0 after 74 usecs
