Details
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_limit: avoid possible divide error in nft_limit_init
div_u64() divides u64 by u32.
nft_limit_init() wants to divide u64 by u64, use the appropriate
math function (div64_u64)
divide error: 0000 [#1] PREEMPT SMP KASAN
