Technical description

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

octeontx2-af: Block VFs from clobbering special CGX PKIND state

PF and VF NIX LFs that share a CGX LMAC reuse the same hardware PKIND

programming. When HiGig2 or EDSA parsing is enabled, a VF NIX LF alloc must

not reset the LMAC RX PKIND or default TX parse config over the PF setup.

Add cgx_get_pkind() and rvu_cgx_is_pkind_config_permitted() so VFs skip

cgx_set_pkind(), rvu_npc_set_pkind(), and NIX_AF_LFX_TX_PARSE_CFG updates

when the LMAC is using NPC_RX_HIGIG_PKIND or NPC_RX_EDSA_PKIND.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
