| Vector | AV:A/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.5.4
Description
The issue is related to the mwifiex ret wmm get status() function in the Marvell WiFi driver of the Linux kernel, which allows a remote AP to trigger a heap-based buffer overflow due to an incorrect memcpy. This can lead to a denial of service.
Recommendations
For Linux kernel versions prior to 5.5.4, update to version 5.5.4 or later to resolve the issue. As a temporary workaround, consider disabling the
mwifiex ret wmm get status() function until a patch is available. Restrict access to the vulnerable Marvell WiFi driver to minimize the risk of exploitation.Fix
