Amendment

The Red Hat security team deemed this advisory irrelevant for RHEL:9.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-cross-headers package and not the kernel-cross-headers package as distributed by RHEL.

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nft_payload: incorrect arithmetics when fetching VLAN header bits

If the offset + length goes over the ethernet + vlan header, then the length is adjusted to copy the bytes that are within the boundaries of the vlan_ethhdr scratchpad area. The remaining bytes beyond ethernet + vlan header are copied directly from the skbuff data area.

Fix incorrect arithmetic operator: subtract, not add, the size of the vlan header in case of double-tagged packets to adjust the length accordingly to address CVE-2023-0179.
