CVE-2023-53033

Summary (CVE-2023-53033): The Linux kernel netfilter NFT payload code incorrectly handles VLAN header bit extraction due to arithmetic that adds, not subtracts, the VLAN header size when computing the copy length for double-tagged packets. This could permit out-of-bounds handling in VLAN header p...
