Summary
In the Linux kernel, the following vulnerability has been resolved:
ntb_hw_switchtec: Fix shift-out-of-bounds in switchtec_ntb_mw_set_trans
There is a kernel API ntb_mw_clear_trans() would pass 0 to both addr and
size. This would make xlate_pos negative.

Title
netfilter: br_netfilter: skip conntrack input hook for promisc packets
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: br_netfilter: skip conntrack input hook for promisc packets
For historical reasons, when bridge device is in promisc mode, packets
that are directed to the taps follow bridge input hook path. This patch
adds a workaround to reset conntrack for these packets.
Jianbo Liu reports warning splats in their test infrastructure where
cloned packets reach the br_netfilter input hook to confirm the
conntrack object.
Scratch one bit from BR_INPUT_SKB_CB to annotate that this packet has
reached the input hook because it is passed up to the bridge device to
reach the taps.

Title
netfilter: bridge: confirm multicast packets before passing them up the stack
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: bridge: confirm multicast packets before passing them up the stack
conntrack nf_confirm logic cannot handle cloned skbs referencing
the same nf_conn entry, which will happen for multicast (broadcast)
frames on bridges.
Example:
macvlan0
|
br0
/ \
ethX ethY
ethX (or Y) receives a L2 multicast or broadcast packet containing
an IP packet, flow is not yet in conntrack table.
1. skb passes through bridge and fake-ip (br_netfilter)Prerouting.
-> skb->_nfct now references a unconfirmed entry
2. skb is broad/mcast packet. bridge now passes clones out on each bridge
interface.
3. skb gets passed up the stack.
4. In macvlan case, macvlan driver retains clone(s) of the mcast skb
and schedules a work queue to send them out on the lower devices.
The clone skb->_nfct is not a copy, it is the same entry as the
original skb. The macvlan rx handler then returns RX_HANDLER_PASS.
5. Normal conntrack hooks (in NF_INET_LOCAL_IN) confirm the orig skb.
The Macvlan broadcast worker and normal confirm path will race.
This race will not happen if step 2 already confirmed a clone. In that
case later steps perform skb_clone() with skb->_nfct already confirmed (in
hash table). This works fine.
But such confirmation won't happen when eb/ip/nftables rules dropped the
packets before they reached the nf_confirm step in postrouting.
Pablo points out that nf_conntrack_bridge doesn't allow use of stateful
nat, so we can safely discard the nf_conn entry and let inet call
conntrack again.
This doesn't work for bridge netfilter: skb could have a nat
transformation. Also bridge nf prevents re-invocation of inet prerouting
via 'sabotage_in' hook.
Work around this problem by explicit confirmation of the entry at LOCAL_IN
time, before upper layer has a chance to clone the unconfirmed entry.
The downside is that this disables NAT and conntrack helpers.
Alternative fix would be to add locking to all code parts that deal with
unconfirmed packets, but even if that could be done in a sane way this
opens up other problems, for example:
-m physdev --physdev-out eth0 -j SNAT --snat-to 1.2.3.4
-m physdev --physdev-out eth1 -j SNAT --snat-to 1.2.3.5
For multicast case, only one of such conflicting mappings will be
created, conntrack only handles 1:1 NAT mappings.
Users should set create a setup that explicitly marks such traffic
NOTRACK (conntrack bypass) to avoid this, but we cannot auto-bypass
them, ruleset might have accept rules for untracked traffic already,
so user-visible behaviour would change.
Severity
No CVSS data available.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: bridge: confirm multicast packets before passing them up the stack\n\nconntrack nf_confirm logic cannot handle cloned skbs referencing\nthe same nf_conn entry, which will happen for multicast (broadcast)\nframes on bridges.\n\n Example:\n macvlan0\n |\n br0\n / \\\n ethX ethY\n\n ethX (or Y) receives a L2 multicast or broadcast packet containing\n an IP packet, flow is not yet in conntrack table.\n\n 1. skb passes through bridge and fake-ip (br_netfilter)Prerouting.\n -\u003e skb-\u003e_nfct now references a unconfirmed entry\n 2. skb is broad/mcast packet. bridge now passes clones out on each bridge\n interface.\n 3. skb gets passed up the stack.\n 4. In macvlan case, macvlan driver retains clone(s) of the mcast skb\n and schedules a work queue to send them out on the lower devices.\n\n The clone skb-\u003e_nfct is not a copy, it is the same entry as the\n original skb. The macvlan rx handler then returns RX_HANDLER_PASS.\n 5. Normal conntrack hooks (in NF_INET_LOCAL_IN) confirm the orig skb.\n\nThe Macvlan broadcast worker and normal confirm path will race.\n\nThis race will not happen if step 2 already confirmed a clone. In that\ncase later steps perform skb_clone() with skb-\u003e_nfct already confirmed (in\nhash table). This works fine.\n\nBut such confirmation won\u0027t happen when eb/ip/nftables rules dropped the\npackets before they reached the nf_confirm step in postrouting.\n\nPablo points out that nf_conntrack_bridge doesn\u0027t allow use of stateful\nnat, so we can safely discard the nf_conn entry and let inet call\nconntrack again.\n\nThis doesn\u0027t work for bridge netfilter: skb could have a nat\ntransformation. Also bridge nf prevents re-invocation of inet prerouting\nvia \u0027sabotage_in\u0027 hook.\n\nWork around this problem by explicit confirmation of the entry at LOCAL_IN\ntime, before upper layer has a chance to clone the unconfirmed entry.\n\nThe downside is that this disables NAT and conntrack helpers.\n\nAlternative fix would be to add locking to all code parts that deal with\nunconfirmed packets, but even if that could be done in a sane way this\nopens up other problems, for example:\n\n-m physdev --physdev-out eth0 -j SNAT --snat-to 1.2.3.4\n-m physdev --physdev-out eth1 -j SNAT --snat-to 1.2.3.5\n\nFor multicast case, only one of such conflicting mappings will be\ncreated, conntrack only handles 1:1 NAT mappings.\n\nUsers should set create a setup that explicitly marks such traffic\nNOTRACK (conntrack bypass) to avoid this, but we cannot auto-bypass\nthem, ruleset might have accept rules for untracked traffic already,\nso user-visible behaviour would change."

Title
fou: Fix null-ptr-deref in GRO.
Summary
In the Linux kernel, the following vulnerability has been resolved:
fou: Fix null-ptr-deref in GRO.
We observed a null-ptr-deref in fou_gro_receive() while shutting down
a host. [0]
The NULL pointer is sk->sk_user_data, and the offset 8 is of protocol
in struct fou.
When fou_release() is called due to netns dismantle or explicit tunnel
teardown, udp_tunnel_sock_release() sets NULL to sk->sk_user_data.
Then, the tunnel socket is destroyed after a single RCU grace period.
So, in-flight udp4_gro_receive() could find the socket and execute the
FOU GRO handler, where sk->sk_user_data could be NULL.
Let's use rcu_dereference_sk_user_data() in fou_from_sock() and add NULL
checks in FOU GRO handlers.

Title
KVM: nSVM: Ignore nCR3[4:0] when loading PDPTEs from memory
Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: nSVM: Ignore nCR3[4:0] when loading PDPTEs from memory
Ignore nCR3[4:0] when loading PDPTEs from memory for nested SVM, as bits
4:0 of CR3 are ignored when PAE paging is used, and thus VMRUN doesn't
enforce 32-byte alignment of nCR3.
In the absolute worst case scenario, failure to ignore bits 4:0 can result
in an out-of-bounds read, e.g. if the target page is at the end of a
memslot, and the VMM isn't using guard pages.
Per the APM:
The CR3 register points to the base address of the page-directory-pointer
table. The page-directory-pointer table is aligned on a 32-byte boundary,
with the low 5 address bits 4:0 assumed to be 0.
And the SDM's much more explicit:
4:0 Ignored
Note, KVM gets this right when loading PDPTRs, it's only the nSVM flow
that is broken.

Title
bpf: devmap: provide rxq after redirect
Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: devmap: provide rxq after redirect
rxq contains a pointer to the device from where
the redirect happened. Currently, the BPF program
that was executed after a redirect via BPF_MAP_TYPE_DEVMAP*
does not have it set.
This is particularly bad since accessing ingress_ifindex, e.g.
SEC("xdp")
int prog(struct xdp_md *pkt)
{
return bpf_redirect_map(&dev_redirect_map, 0, 0);
}
SEC("xdp/devmap")
int prog_after_redirect(struct xdp_md *pkt)
{
bpf_printk("ifindex %i", pkt->ingress_ifindex);
return XDP_PASS;
}
depends on access to rxq, so a NULL pointer gets dereferenced:
