CVE-2020-12465

A memory overflow and data corruption flaw were found in the Mediatek MT76 driver module for WiFi in mt76_add_fragment in drivers/net/wireless/mediatek/mt76/dma.c. An oversized packet with too many rx fragments causes an overflow and corruption in memory of adjacent pages. A local attacker with a special user or root privileges can cause a denial of service or a leak of internal kernel information.

Mitigation

Mitigation for this issue is to skip loading the affected module mt76 onto the system until we have a fix available. This can be done by a blacklist mechanism and ensures the driver is not loaded at the boot time.

How do I blacklist a kernel module to prevent it from loading automatically?
