CVE-2021-47270
Last modified
CVE-2021-47270 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: usb: fix various gadgets null ptr deref on 10gbps cabling. This avoids a null pointer dereference in f_{ecm,eem,hid,loopback,printer,rndis,serial,sourcesink,subset,tcm} by simply reusing the 5gbps config for 10gbps.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
