CVE-2019-11884: Bluetooth: hidp: fix buffer overflow · torvalds/linux@a1616a5
The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel before 5.0.15 allows a local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not end with a ‘\0’ character.

Bluetooth: hidp: fix buffer overflow
Struct ca is copied from userspace. It is not checked whether the “name” field is NULL terminated, which allows local users to obtain potentially sensitive information from kernel stack memory, via a HIDPCONNADD command.
This vulnerability is similar to CVE-2011-1079.
