Overview

CVE-2022-50498 is a medium-severity vulnerability. It was published on October 4, 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:

eth: alx: take rtnl_lock on resume

Zbynek reports that alx trips an rtnl assertion on resume:

RTNL: assertion failed at net/core/dev.c (2891)

RIP: 0010:netif_set_real_num_tx_queues+0x1ac/0x1c0

Call Trace:

<TASK>

__alx_open+0x230/0x570 [alx]

alx_resume+0x54/0x80 [alx]

? pci_legacy_resume+0x80/0x80

async_resume+0x19/0x30

async_run_entry_fn+0x30/0x130

process_one_work+0x1e5/0x3b0

indeed the driver does not hold rtnl_lock during its internal close

and re-open functions during suspend/resume. Note that this is not

a huge bug as the driver implements its own locking, and does not

implement changing the number of queues, but we need to silence

the splat.

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.
