Description CFuga 2022-03-16 16:28:06 UTC 
net/netfilter/nf_dup_netdev.c in the Linux kernel 5.4 through 5.6.10 allows local users to gain privileges because of a heap out-of-bounds write. This is related to nf_tables_offload.

https://nickgregory.me/linux/security/2022/03/12/cve-2022-25636/

Fixed in 5.15.26, 5.10.102, 5.4.182.

Pablo Neira Ayuso:
      netfilter: nf_tables_offload: incorrect flow offload action array size


Reproducible: Always
