Mar 01, 2025 cve

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
