CVE-2019-0136
Description
A flaw was found in the Linux kernel’s implementation of wireless drivers for the Intel PROset wireless hardware. This flaw allows an unauthorized attacker within the wireless radio range to cause the driver and the system to disconnect from the wireless network, triggering the operating system to lose network connectivity while the system is not connected. The highest threat from this vulnerability is system availability.
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).
