| Vector | AV:N/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions 3.x.x through 4.17.x
Description
A heap-based buffer overflow was discovered in the Marvell WiFi chip driver of the Linux kernel. The issue occurs when handling remote devices' country settings during connection negotiation, potentially allowing a remote device to cause a denial of service or possibly execute arbitrary code. The vulnerability is related to the
mwifiex process country ie() function and can be exploited by a remote attacker to access confidential data, compromise data integrity, or cause a denial of service.Recommendations
For Linux kernel versions 3.x.x through 4.17.x, update to version 4.18.0 or later to resolve the issue. As a temporary workaround, consider disabling the
mwifiex process country ie() function in the Marvell WiFi chip driver to minimize the risk of exploitation. Restrict access to the Marvell WiFi chip driver module to reduce the attack surface until a patch is applied.Exploit
