Linux Kernel up to 5.17.2 module_init/module_exit debug log file

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Linux Kernel up to 5.17.2. It has been rated as problematic. This issue affects the function module_init/module_exit. The manipulation with an unknown input leads to a debug log file vulnerability. Using CWE to declare the problem leads to CWE-534. This entry has been deprecated because its abstraction was too low-level. See CWE-532. Impacted is confidentiality. The summary by CVE is:

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

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2022-49100 since 02/26/2025. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1592 for this issue.
