CVE-2026-31604
개요
A flaw was found in the Linux kernel's rtw88 Wi-Fi driver. This vulnerability occurs when the driver fails to release a reference to a Universal Serial Bus (USB) device during certain probe errors, such as when descriptor parsing fails. A local attacker could potentially trigger this condition by plugging in a malformed USB device, leading to memory leaks. Over time, these unreleased resources could accumulate, potentially causing system instability or a denial of service.
CVSS (Common Vulnerability Scoring System) 점수 세부 사항
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

취약점 이해 (CWE)
Availability
Technical Impact: DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
An adversary that can cause a resource counter to become inaccurate may be able to create situations where resources are not accounted for and not released, thus causing resources to become scarce for future needs.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
An adversary that can cause a resource counter to become inaccurate may be able to force an error that causes the product to crash or exit out of its current operation.
