Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2020-11668
CWEhttps://cwe.mitre.org/data/definitions/476.html

In the Linux kernel before 5.6.1, drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink camera USB driver) mishandles invalid descriptors, aka CID-a246b4d54770.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
