Overview

CVE-2022-49790 is a medium-severity vulnerability. It was published on May 1, 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:

Input: iforce - invert valid length check when fetching device IDs

syzbot is reporting uninitialized value at iforce_init_device() [1], for

commit 6ac0aec6b0a6 ("Input: iforce - allow callers supply data buffer

when fetching device IDs") is checking that valid length is shorter than

bytes to read. Since iforce_get_id_packet() stores valid length when

returning 0, the caller needs to check that valid length is longer than or

equals to bytes to read.

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.
