CVE-2019-11884: Infoleak

First published: Fri May 10 2019(Updated: )

A flaw was found in the kernels implementation of the bluetooth HIDP (Human Interface Device Protocol). A local attacker with access permissions to the bluetooth device can issue an IOCTL which will trigger the do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c.c. This function can potentially leak potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not correctly NULL terminated.
