Name of the Vulnerable Software and Affected Versions MediaTek microchips versions 2.0.2

Description The issue is related to the mishandling of IEEE 1905 protocols in MediaTek microchips, which can lead to an out-of-bounds read. This can potentially allow a remote attacker to cause a denial of service. The affected chipsets include MT7603E, MT7613, MT7615, MT7622, MT7628, MT7629, and MT7915.

Recommendations For version 2.0.2, consider disabling the handling of IEEE 1905 protocols as a temporary workaround until a patch is available. Restrict access to the vulnerable chipsets to minimize the risk of exploitation. Avoid using the affected software versions until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
