Red Hat update for kernel

1) Resource exhaustion

EUVDB-ID: #VU12259

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L/E:P/RL:O/RC:C]

CVE-ID: CVE-2016-3672

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: Yes

The vulnerability allows a local attacker to bypass security restrictions on the target system.

19) Out-of-bounds write

EUVDB-ID: #VU9771

Risk: Low

CVSSv3.1: 5.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-17558

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

The vulnerability allows a local attacker to cause DoS condition on the target system.

The weakness exists due to the usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux kernel does not consider the maximum number of configurations and interfaces before attempting to release resources. A local attacker can supply specially crafted USB device, trigger out-of-bounds write access and cause the system to crash.

Successful exploitation of the vulnerability results in denial of service.
