In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_set_pipapo: prevent overflow in lookup table allocation
When calculating the lookup table size, ensure the following multiplication does not overflow:
Then, use check_mul_overflow() to multiply by bucket size and then use check_add_overflow() to the alignment for avx2 (if needed). Finally, add lt_size_check_overflow() helper and use it to consolidate this.
While at it, replace leftover allocation using the GFP_KERNEL to GFP_KERNEL_ACCOUNT for consistency, in pipapo_resize().
