NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel package and not the kernel package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
The nft_flush_table function in net/netfilter/nf_tables_api.c in the Linux kernel before 3.18.5 mishandles the interaction between cross-chain jumps and ruleset flushes, which allows local users to cause a denial of service (panic) by leveraging the CAP_NET_ADMIN capability.
