Buffer overflow

Yubico libu2f-host 1.1.6 contains unchecked buffers in devs.c, which could enable a malicious token to exploit a buffer overflow. An attacker could use this to attempt to execute malicious code using a crafted USB device masquerading as a security token on a computer where the affected library is...

Out-of-bounds

The function hsogetconfigdata in drivers/net/usb/hso.c in the Linux kernel through 4.19.8 reads ifnum from the USB device as a u8 and uses it to index a small array, resulting in an object out-of-bounds OOB read that potentially allows arbitrary read in the kernel address space...
