NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-abi-whitelists package and not the kernel-abi-whitelists package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

The sock_setsockopt function in net/core/sock.c in the Linux kernel before 4.8.14 mishandles negative values of sk_sndbuf and sk_rcvbuf, which allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option.
