| Vetor | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.1.6
Description
The issue is related to the mwifiex tm cmd in the Linux kernel, which has some error-handling cases that did not free allocated hostcmd memory. This will cause a memory leak and denial of service. An attacker can exploit this to cause a denial of service.
Recommendations
For Linux kernel versions prior to 5.1.6, update to version 5.1.6 or later to resolve the issue. As a temporary workaround, consider disabling the mwifiex tm cmd function until a patch is available. Restrict access to the vulnerable cfg80211.c module to minimize the risk of exploitation.
