Linux kernel stack buffer overflow in nftables(CVE-2023-0179)
The vulnerability consists of a stack BOF due to an integer underflow vulnerability inside the nft_payload_copy_vlan function, which is invoked with nft_payload expressions as long as a VLAN tag is present in the current skb.
⚠️The exploitation could allow the leakage of both stack and heap addresses and, potentially, a LPE to the root user via arbitrary code execution.
