Overview

CVE-2022-49100 is a medium-severity vulnerability. It was published on February 26, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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.

Example 1: (System.map)

ffffffff832fc78c t init

ffffffff832fc79e t init

ffffffff832fc8f8 t init

Example 2: (initcall_debug log)

calling init+0x0/0x12 @ 1

initcall init+0x0/0x12 returned 0 after 15 usecs

calling init+0x0/0x60 @ 1

initcall init+0x0/0x60 returned 0 after 2 usecs

calling init+0x0/0x9a @ 1

initcall init+0x0/0x9a returned 0 after 74 usecs

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
