Title
netfilter: nf_conncount: Fully initialize struct nf_conncount_tuple in insert_tree()
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_conncount: Fully initialize struct nf_conncount_tuple in insert_tree()
Since commit b36e4523d4d5 ("netfilter: nf_conncount: fix garbage
collection confirm race"), `cpu` and `jiffies32` were introduced to
the struct nf_conncount_tuple.
The commit made nf_conncount_add() initialize `conn->cpu` and
`conn->jiffies32` when allocating the struct.
In contrast, count_tree() was not changed to initialize them.
By commit 34848d5c896e ("netfilter: nf_conncount: Split insert and
traversal"), count_tree() was split and the relevant allocation
code now resides in insert_tree().
Initialize `conn->cpu` and `conn->jiffies32` in insert_tree().

A remote host simply sending connections to a box carrying an iptables `-m connlimit` rule or an OVS conntrack zone limit drives the code.\nAC:L - The fields are left uninitialized on every `insert_tree()` allocation, and the attacker controls both sides of the conditioning window by opening many concurrent connections from the same source prefix so entries remain unconfirmed when `find_or_evict()` walks them. `CONFIG_NETFILTER_XT_MATCH_CONNLIMIT` is shipped by all mainstream distributions and connlimit/OVS ct-limit rules are common on internet-facing and cloud deployments, so no rare configuration is required.\nPR:N - The path is reached from raw inbound IP packets processed in a netfilter hook before any authentication or authorization; no account, credential, or capability on the target is needed. The alternative local trigger via unprivileged user namespaces would only be PR:L, so the unauthenticated remote scenario dominates.\nUI:N - Exploitation requires only that the attacker transmit packets to the target; no administrator or user action is needed once the connlimit/ct-limit rule is in place.\nS:U - The uninitialized read and its consequences are confined to the kernel\u0027s own nf_conncount accounting state within the same security authority; no VM, IOMMU, container, or sandbox boundary is crossed.\nC:L - `conn-\u003ecpu` and `conn-\u003ejiffies32` are read from recycled slab memory (the cache is created with flags 0, so it is merge-eligible with other same-size caches) and the values steer whether a packet is accepted or dropped, giving a remote observer a limited, bounded inference channel into residual kernel heap contents. Nothing is copied out directly, so the disclosure is limited rather than arbitrary read.\nI:L - The garbage values corrupt nf_conncount\u0027s eviction heuristic so `list-\u003ecount` no longer reflects the real number of tracked connections, causing the administrator-configured connlimit / OVS per-zone limit to be enforced against a wrong count and letting an attacker exceed it. This is a limited modification of security-relevant kernel state, not an arbitrary write or control-flow hijack.\nA:L - Under-counting defeats a connection-limit control that exists to prevent resource exhaustion, letting an attacker consume more connections than permitted, while transient over-counting drops legitimate traffic from an affected source. The fields are only compared, never dereferenced or used as indices, so there is no oops, panic, hang, or memory corruption \u2014 the result is degradation rather than total loss of availability."

Title
eth: bnxt: do not update checksum in bnxt_xdp_build_skb()
Summary
In the Linux kernel, the following vulnerability has been resolved:
eth: bnxt: do not update checksum in bnxt_xdp_build_skb()
The bnxt_rx_pkt() updates ip_summed value at the end if checksum offload
is enabled.
When the XDP-MB program is attached and it returns XDP_PASS, the
bnxt_xdp_build_skb() is called to update skb_shared_info.
The main purpose of bnxt_xdp_build_skb() is to update skb_shared_info,
but it updates ip_summed value too if checksum offload is enabled.
This is actually duplicate work.
When the bnxt_rx_pkt() updates ip_summed value, it checks if ip_summed
is CHECKSUM_NONE or not.
It means that ip_summed should be CHECKSUM_NONE at this moment.
But ip_summed may already be updated to CHECKSUM_UNNECESSARY in the
XDP-MB-PASS path.
So the by skb_checksum_none_assert() WARNS about it.
This is duplicate work and updating ip_summed in the
bnxt_xdp_build_skb() is not needed.
Splat looks like:

The XDP-MB program and jumbo MTU are properties of whether the target is vulnerable at all, not extra effort the attacker must expend.\nPR:N - The trigger is an unauthenticated raw packet consumed by the NIC driver before any protocol-level authentication or socket ownership check. The attacker needs no account, credential, or capability on the target.\nUI:N - The packet is processed automatically by the NAPI poll loop as soon as it arrives on the wire. No administrator or user action is needed at exploitation time.\nS:U - The fault and its consequences are confined to the kernel of the receiving host, with no crossing of a VM, IOMMU, or sandbox boundary. This is a standard in-kernel driver defect.\nC:N - The defect is a redundant store of the exact value the driver writes moments later, so no out-of-bounds or freed memory is ever read and nothing is returned to the attacker. The remote attacker who triggers the splat has no channel to read the resulting dmesg output.\nI:N - No attacker-controlled data is written anywhere; the duplicated ip_summed/csum_level assignment stores the same hardware-derived values that bnxt_rx_pkt() stores unconditionally. There is no OOB write, type confusion, or control-flow primitive.\nA:H - Every qualifying inbound packet drives the kernel into a WARN splat in softirq context, which is an immediate kernel panic on the widely used panic_on_warn=1 configuration, taking the whole host down. Even short of panic it taints the kernel and aborts orderly processing from the interrupt path."

Title
net/mlx5: Bridge, fix the crash caused by LAG state check
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Bridge, fix the crash caused by LAG state check
When removing LAG device from bridge, NETDEV_CHANGEUPPER event is
triggered. Driver finds the lower devices (PFs) to flush all the
offloaded entries. And mlx5_lag_is_shared_fdb is checked, it returns
false if one of PF is unloaded. In such case,
mlx5_esw_bridge_lag_rep_get() and its caller return NULL, instead of
the alive PF, and the flush is skipped.
Besides, the bridge fdb entry's lastuse is updated in mlx5 bridge
event handler. But this SWITCHDEV_FDB_ADD_TO_BRIDGE event can be
ignored in this case because the upper interface for bond is deleted,
and the entry will never be aged because lastuse is never updated.
To make things worse, as the entry is alive, mlx5 bridge workqueue
keeps sending that event, which is then handled by kernel bridge
notifier. It causes the following crash when accessing the passed bond
netdev which is already destroyed.
To fix this issue, remove such checks. LAG state is already checked in
commit 15f8f168952f ("net/mlx5: Bridge, verify LAG state when adding
bond to bridge"), driver still need to skip offload if LAG becomes
invalid state after initialization.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5: Bridge, fix the crash caused by LAG state check\n\nWhen removing LAG device from bridge, NETDEV_CHANGEUPPER event is\ntriggered. Driver finds the lower devices (PFs) to flush all the\noffloaded entries. And mlx5_lag_is_shared_fdb is checked, it returns\nfalse if one of PF is unloaded. In such case,\nmlx5_esw_bridge_lag_rep_get() and its caller return NULL, instead of\nthe alive PF, and the flush is skipped.\n\nBesides, the bridge fdb entry\u0027s lastuse is updated in mlx5 bridge\nevent handler. But this SWITCHDEV_FDB_ADD_TO_BRIDGE event can be\nignored in this case because the upper interface for bond is deleted,\nand the entry will never be aged because lastuse is never updated.\n\nTo make things worse, as the entry is alive, mlx5 bridge workqueue\nkeeps sending that event, which is then handled by kernel bridge\nnotifier. It causes the following crash when accessing the passed bond\nnetdev which is already destroyed.\n\nTo fix this issue, remove such checks. LAG state is already checked in\ncommit 15f8f168952f (\"net/mlx5: Bridge, verify LAG state when adding\nbond to bridge\"), driver still need to skip offload if LAG becomes\ninvalid state after initialization.\n\n Oops: stack segment: 0000 [#1] SMP\n CPU: 3 UID: 0 PID: 23695 Comm: kworker/u40:3 Tainted: G OE 6.11.0_mlnx #1\n Tainted: [O]=OOT_MODULE, [E]=UNSIGNED_MODULE\n Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014\n Workqueue: mlx5_bridge_wq mlx5_esw_bridge_update_work [mlx5_core]\n RIP: 0010:br_switchdev_event+0x2c/0x110 [bridge]\n Code: 44 00 00 48 8b 02 48 f7 00 00 02 00 00 74 69 41 54 55 53 48 83 ec 08 48 8b a8 08 01 00 00 48 85 ed 74 4a 48 83 fe 02 48 89 d3 \u003c4c\u003e 8b 65 00 74 23 76 49 48 83 fe 05 74 7e 48 83 fe 06 75 2f 0f b7\n RSP: 0018:ffffc900092cfda0 EFLAGS: 00010297\n RAX: ffff888123bfe000 RBX: ffffc900092cfe08 RCX: 00000000ffffffff\n RDX: ffffc900092cfe08 RSI: 0000000000000001 RDI: ffffffffa0c585f0\n RBP: 6669746f6e690a30 R08: 0000000000000000 R09: ffff888123ae92c8\n R10: 0000000000000000 R11: fefefefefefefeff R12: ffff888123ae9c60\n R13: 0000000000000001 R14: ffffc900092cfe08 R15: 0000000000000000\n FS: 0000000000000000(0000) GS:ffff88852c980000(0000) knlGS:0000000000000000\n CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n CR2: 00007f15914c8734 CR3: 0000000002830005 CR4: 0000000000770ef0\n DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n PKRU: 55555554\n Call Trace:\n \u003cTASK\u003e\n ? __die_body+0x1a/0x60\n ? die+0x38/0x60\n ? do_trap+0x10b/0x120\n ? do_error_trap+0x64/0xa0\n ? exc_stack_segment+0x33/0x50\n ? asm_exc_stack_segment+0x22/0x30\n ? br_switchdev_event+0x2c/0x110 [bridge]\n ? sched_balance_newidle.isra.149+0x248/0x390\n notifier_call_chain+0x4b/0xa0\n atomic_notifier_call_chain+0x16/0x20\n mlx5_esw_bridge_update+0xec/0x170 [mlx5_core]\n mlx5_esw_bridge_update_work+0x19/0x40 [mlx5_core]\n process_scheduled_works+0x81/0x390\n worker_thread+0x106/0x250\n ? bh_worker+0x110/0x110\n kthread+0xb7/0xe0\n ? kthread_park+0x80/0x80\n ret_from_fork+0x2d/0x50\n ? kthread_park+0x80/0x80\n ret_from_fork_asm+0x11/0x20\n \u003c/TASK\u003e"

Use-after-free of a netdev with a repeating trigger is a strong heap-spray primitive.\nA:H - The commit documents a reproducible kernel oops (\"stack segment\" fault in br_switchdev_event) from the mlx5_bridge_wq worker, and because the stale entries never age out the crash path is re-entered every second.

Title
net_sched: Prevent creation of classes with TC_H_ROOT
Summary
In the Linux kernel, the following vulnerability has been resolved:
net_sched: Prevent creation of classes with TC_H_ROOT
The function qdisc_tree_reduce_backlog() uses TC_H_ROOT as a termination
condition when traversing up the qdisc tree to update parent backlog
counters. However, if a class is created with classid TC_H_ROOT, the
traversal terminates prematurely at this class instead of reaching the
actual root qdisc, causing parent statistics to be incorrectly maintained.
In case of DRR, this could lead to a crash as reported by Mingi Cho.
Prevent the creation of any Qdisc class with classid TC_H_ROOT
(0xFFFFFFFF) across all qdisc types, as suggested by Jamal.

7.8 (High)

No real root in the init namespace is needed.\nUI:N - The attacker performs every step themselves \u2014 netlink configuration and packet transmission \u2014 with no action required from any other user or administrator.\nS:U - The corruption stays within the kernel\u0027s own security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The stale active-list entry produces a use-after-free on a kzalloc\u0027d drr_class object; the attacker can reclaim that slab and have the kernel read pointers and data out of attacker-adjacent memory, and the resulting primitives can be leveraged for arbitrary kernel memory disclosure.\nI:H - The UAF yields both an unlink write (list_del on freed cl-\u003ealist) and an indirect call through cl-\u003eqdisc-\u003eops-\u003epeek read from reclaimed heap memory, giving arbitrary write and control-flow hijack potential, i.e. full kernel integrity loss.\nA:H - Even without full exploitation, the dangling list entry causes a use-after-free oops in softirq context on the next dequeue, and the broken accounting permanently stalls the qdisc (drr_dequeue always returns NULL), halting transmission on the device \u2014 a repeatable kernel crash/DoS."

Title
net/mlx5: handle errors in mlx5_chains_create_table()
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: handle errors in mlx5_chains_create_table()
In mlx5_chains_create_table(), the return value of mlx5_get_fdb_sub_ns()
and mlx5_get_flow_namespace() must be checked to prevent NULL pointer
dereferences. If either function fails, the function should log error
message with mlx5_core_warn() and return error pointer.
Severity
No CVSS data available.

Title
drm/hyperv: Fix address space leak when Hyper-V DRM device is removed
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/hyperv: Fix address space leak when Hyper-V DRM device is removed
When a Hyper-V DRM device is probed, the driver allocates MMIO space for
the vram, and maps it cacheable. If the device removed, or in the error
path for device probing, the MMIO space is released but no unmap is done.
Consequently the kernel address space for the mapping is leaked.
Fix this by adding iounmap() calls in the device removal path, and in the
error path during device probing.
Severity
No CVSS data available.
