Description
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.
