CVE-2019-11884

Public on 2019-05-29

Description
A flaw was found in the Linux kernel's implementation of the Bluetooth Human Interface Device Protocol (HIDP). 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 leak potentially sensitive information from the kernel stack memory via a HIDPCONNADD command because a name field may not be correctly NULL terminated.
