CVE-2025-38293

Description

A flaw was found in the Linux kernel's ath11k Wi-Fi (WLAN) driver. During a WLAN recovery process, specifically when a virtual interface (vif) is being removed, a list node can become corrupted. This corruption can lead to a kernel panic, effectively causing a Denial of Service (DoS) for the system. A local attacker could potentially exploit this to crash the system.

Common Vulnerability Scoring System (CVSS) Score Details

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).

The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)

Confidentiality

Technical Impact: Read Memory; Read Application Data

When reusing a resource such as memory or a program variable, the original contents of that resource may not be cleared before it is sent to an untrusted party.

Availability

Technical Impact: DoS: Crash, Exit, or Restart

The uninitialized resource may contain values that cause program flow to change in ways that the programmer did not intend.
