kernel: sensitive information disclosure from kernel stack memory via HIDPCONNADD command

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 dohidpsockioctl function in net/bluetooth/hidp/sock.c.c. This function can leak...

kernel: use-after-free Read in vhost_transport_send_pkt

A flaw was found where an attacker may be able to have an uncontrolled read to kernel-memory from within a vm guest. A race condition between connect and close function may allow an attacker using the AFVSOCK protocol to gather a 4 byte information leak or possibly impersonate AFVSOCK messages...
