CVE-2022-49100
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
virtio_console: eliminate anonymous module_init & module_exit
Eliminate anonymous module_init() and module_exit(), which can lead to confusion or ambiguity when reading System.map, crashes/oops/bugs, or an initcall_debug log.
Give each of these init and exit functions unique driver-specific names to eliminate the anonymous names.
