Severity ?
7.9 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: fix VF bringup affecting PF promiscuous state Mbox handling of nix_set_rx_mode for a VF with promiscuous and all_multi flags set to false causes deletion of the PF's promiscuous and allmulti MCAM rules. This occurs because the APIs that enable/disable these rules operate only on the PF, even when the mbox request is made via a VF interface. Guard both rvu_npc_enable_allmulti_entry() and rvu_npc_enable_promisc_entry() disable paths with an is_vf() check so that a VF bringing up or tearing down its interface cannot inadvertently clear the PF's MCAM rules.

no race or victim timing is required.\\nPR:L - Only guest/namespace CAP_NET_ADMIN (or equivalent root in an SR-IOV-assigned VM) is needed to manage the VF netdev; host init-namespace root is not required and user namespaces cannot reach this hardware path without the VF device.\\nUI:N - No victim interaction is needed; the attacker initiates VF interface bringup/teardown or rx_mode updates that invoke otx2_do_set_rx_mode/otx2vf_do_set_rx_mode and the AF mbox handler.\\nS:C - A VF tenant can alter PF-side NPC MCAM promiscuous/allmulti rules (rvu_npc_enable_promisc_entry/rvu_npc_enable_allmulti_entry mask pcifunc to the PF), crossing the SR-IOV isolation boundary between guest/tenant and host/provider packet filtering.\\nC:L - Disabling the PF promiscuous/allmulti MCAM entries can blind host IDS/tcpdump and other monitoring that depends on promiscuous reception, reducing visibility into network traffic on the affected PF (limited confidentiality impact, not arbitrary kernel memory read).\\nI:L - The VF causes unauthorized modification of host-side hardware packet-filter state by disabling PF MCAM promisc/allmulti rules; this is limited integrity impact on network policy rather than arbitrary memory or code execution.\\nA:H - Clearing PF promiscuous and allmulti MCAM rules can break or degrade PF multicast delivery and promiscuous capture/monitoring on internet-facing cloud/edge servers using these NICs, and can be repeated by cycling the VF interface.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"967db3529ecac305d230aa4e60abddf6ab63543a\", \"lessThan\": \"daa2451640a3e0727fd598f5c2ccb8bb4d5a8b9c\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"967db3529ecac305d230aa4e60abddf6ab63543a\", \"lessThan\": \"212c59e5e416859579272288fd325148fc316109\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"967db3529ecac305d230aa4e60abddf6ab63543a\", \"lessThan\": \"53e17d9ed779ad25870abb9c31bc294c71a2278c\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"967db3529ecac305d230aa4e60abddf6ab63543a\", \"lessThan\": \"3de77d2f34c2bc2acaedabc2c5e0a561b85c283a\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"967db3529ecac305d230aa4e60abddf6ab63543a\", \"lessThan\": \"3cf83432e0561aef6d7ec2664909d12d0ff0ffc1\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"967db3529ecac305d230aa4e60abddf6ab63543a\", \"lessThan\": \"fabb881df322da25442f98d23f5fa371e3c78ec4\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/net/ethernet/marvell/octeontx2/af/rvu_nix.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.14\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.14\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.1.178\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.145\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.97\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.40\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.5\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/net/ethernet/marvell/octeontx2/af/rvu_nix.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/daa2451640a3e0727fd598f5c2ccb8bb4d5a8b9c\"}, {\"url\": \"https://git.kernel.org/stable/c/212c59e5e416859579272288fd325148fc316109\"}, {\"url\": \"https://git.kernel.org/stable/c/53e17d9ed779ad25870abb9c31bc294c71a2278c\"}, {\"url\": \"https://git.kernel.org/stable/c/3de77d2f34c2bc2acaedabc2c5e0a561b85c283a\"}, {\"url\": \"https://git.kernel.org/stable/c/3cf83432e0561aef6d7ec2664909d12d0ff0ffc1\"}, {\"url\": \"https://git.kernel.org/stable/c/fabb881df322da25442f98d23f5fa371e3c78ec4\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nocteontx2-af: fix VF bringup affecting PF promiscuous state\\n\\nMbox handling of nix_set_rx_mode for a VF with promiscuous and\\nall_multi flags set to false causes deletion of the PF\u0027s promiscuous\\nand allmulti MCAM rules.
