Issue Overview:
A buffer overflow was discovered in tpacket_rcv() function in the Linux kernel since v4.6-rc1 through v4.13. A number of socket-related syscalls can be made to set up a configuration when each packet received by a network interface can cause writing up to 10 bytes to a kernel memory outside of a kernel buffer. This can cause unspecified kernel data corruption effects, including damage of in-memory and on-disk XFS data. (CVE-2017-14497)
A kernel data leak due to an out-of-bound read was found in the Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and sctp_get_sctp_info() functions present since version 4.7-rc1 through version 4.13. A data leak happens when these functions fill in sockaddr data structures used to export socket’s diagnostic information. As a result, up to 100 bytes of the slab data could be leaked to a userspace. (CVE-2017-7558)
