CVE-2021-43976

Published: 17 November 2021

In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).

From the Ubuntu security team

Brendan Dolan-Gavitt discovered that the Marvell WiFi-Ex USB device driver in the Linux kernel did not properly handle some error conditions. A physically proximate attacker could use this to cause a denial of service (system crash).
