CVE-2020-24586
Description
A flaw was found in the Linux kernels implementation of wifi fragmentation handling. An attacker with the ability to transmit within the wireless transmission range of an access point can abuse a flaw where previous contents of wifi fragments can be unintentionally transmitted to another device.
Mitigation
Mitigation for this issue is either not available or the currently available options does not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
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).

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Files or Directories; Read Application Data
Sensitive data may be exposed to an unauthorized actor in another control sphere. This may have a wide range of secondary consequences that will depend on what data is exposed. One possibility is the exposure of system data - such as file locations, software versions, or device data - that allow an attacker to craft a specific, more effective attack. Alternately, insufficient redaction of Private Personal Information (PPI), Personally Identifiable Information (PII), or other types of information might not harm the secure operation of the product itself, but could be violations of expectations by the product's users.
