Title
net: hns3: do not allow call hns3_nic_net_open repeatedly
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: do not allow call hns3_nic_net_open repeatedly
hns3_nic_net_open() is not allowed to called repeatly, but there
is no checking for this. When doing device reset and setup tc
concurrently, there is a small oppotunity to call hns3_nic_net_open
repeatedly, and cause kernel bug by calling napi_enable twice.
The calltrace information is like below:

Once hns3_nic_net_open() is excute success, the flag
HNS3_NIC_STATE_DOWN will be cleared. So add checking for this
flag, directly return when HNS3_NIC_STATE_DOWN is no set.

Title
fs: sysfs: Fix reference leak in sysfs_break_active_protection()
Summary
In the Linux kernel, the following vulnerability has been resolved:
fs: sysfs: Fix reference leak in sysfs_break_active_protection()
The sysfs_break_active_protection() routine has an obvious reference
leak in its error path. If the call to kernfs_find_and_get() fails then
kn will be NULL, so the companion sysfs_unbreak_active_protection()
routine won't get called (and would only cause an access violation by
trying to dereference kn->parent if it was called). As a result, the
reference to kobj acquired at the start of the function will never be
released.
Fix the leak by adding an explicit kobject_put() call when kn is NULL.

Title
xen-netfront: Add missing skb_mark_for_recycle
Summary
In the Linux kernel, the following vulnerability has been resolved:
xen-netfront: Add missing skb_mark_for_recycle
Notice that skb_mark_for_recycle() is introduced later than fixes tag in
commit 6a5bcd84e886 ("page_pool: Allow drivers to hint on SKB recycling").
It is believed that fixes tag were missing a call to page_pool_release_page()
between v5.9 to v5.14, after which is should have used skb_mark_for_recycle().
Since v6.6 the call page_pool_release_page() were removed (in
commit 535b9c61bdef ("net: page_pool: hide page_pool_release_page()")
and remaining callers converted (in commit 6bfef2ec0172 ("Merge branch
'net-page_pool-remove-page_pool_release_page'")).
This leak became visible in v6.8 via commit dba1b8a7ab68 ("mm/page_pool: catch
page_pool memory leaks").

Simply sending traffic triggers it reliably.\nPR:N - The leak occurs in the driver receive path before any authentication, socket lookup, or filtering, so an entirely unauthenticated remote sender triggers it. No account, session, or local foothold on the guest is required.\nUI:N - No victim action is needed; the vulnerable path executes automatically whenever the guest\u0027s network interface receives frames.

Even without that gate, every device teardown/resume permanently leaks the page_pool with an endlessly rearming work item and \"stalled pool shutdown\" warnings."

Title
netfilter: nf_tables: use timestamp to check for set element timeout
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: use timestamp to check for set element timeout
Add a timestamp field at the beginning of the transaction, store it
in the nftables per-netns area.
Update set backend .insert, .deactivate and sync gc path to use the
timestamp, this avoids that an element expires while control plane
transaction is still unfinished.
.lookup and .update, which are used from packet path, still use the
current time to check if the element has expired. And .get path and dump
also since this runs lockless under rcu read size lock. Then, there is
async gc which also needs to check the current time since it runs
asynchronously from a workqueue.

Title
netfilter: nft_flow_offload: reset dst in route object after setting up flow
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_flow_offload: reset dst in route object after setting up flow
dst is transferred to the flow object, route object does not own it
anymore. Reset dst in route object, otherwise if flow_offload_add()
fails, error path releases dst twice, leading to a refcount underflow.

Title
smb: client: fix UAF in smb2_reconnect_server()
Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix UAF in smb2_reconnect_server()
The UAF bug is due to smb2_reconnect_server() accessing a session that
is already being teared down by another thread that is executing
__cifs_put_smb_ses(). This can happen when (a) the client has
connection to the server but no session or (b) another thread ends up
setting @ses->ses_status again to something different than
SES_EXITING.
To fix this, we need to make sure to unconditionally set
@ses->ses_status to SES_EXITING and prevent any other threads from
setting a new status while we're still tearing it down.
The following can be reproduced by adding some delay to right after
the ipc is freed in __cifs_put_smb_ses() - which will give
smb2_reconnect_server() worker a chance to run and then accessing
@ses->ipc:
kinit ...
mount.cifs //srv/share /mnt/1 -o sec=krb5,nohandlecache,echo_interval=10
[disconnect srv]
ls /mnt/1 &>/dev/null
sleep 30
kdestroy
[reconnect srv]
sleep 10
umount /mnt/1
...

Title
net: ena: Fix incorrect descriptor free behavior
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: ena: Fix incorrect descriptor free behavior
ENA has two types of TX queues:
- queues which only process TX packets arriving from the network stack
- queues which only process TX packets forwarded to it by XDP_REDIRECT
or XDP_TX instructions
The ena_free_tx_bufs() cycles through all descriptors in a TX queue
and unmaps + frees every descriptor that hasn't been acknowledged yet
by the device (uncompleted TX transactions).
The function assumes that the processed TX queue is necessarily from
the first category listed above and ends up using napi_consume_skb()
for descriptors belonging to an XDP specific queue.
This patch solves a bug in which, in case of a VF reset, the
descriptors aren't freed correctly, leading to crashes.

"value": "AV:L - The faulty free is on the driver teardown/reset path (`ena_down()` via ifdown, ethtool ring/channel change, MTU change, XDP detach, or watchdog reset), not on the packet receive path, so entry requires local access to the host even though the bytes that form the bogus sk_buff come from remotely received frames.\nAC:L - With XDP_TX/XDP_REDIRECT traffic flowing, the TX ring always holds uncompleted descriptors, so any down/reset deterministically hits `dev_kfree_skb_any()` on an `xdp_frame`; the attacker can both generate the traffic and induce the teardown, with no race or memory-layout condition outside their control.\nPR:L - In deployments where an XDP program is already attached (a configuration precondition, not an attack step), an unprivileged local user can drive the reset through the ENA watchdog paths that also monitor XDP queues \u2014 missed TX completions and `RESET_SUSPECTED_POLL_STARVATION` under load \u2014 and hypervisor VF resets occur without any local privilege at all.\nUI:N - No victim action is needed; the reset/teardown is initiated by the attacker, the watchdog, or the device itself while XDP frames are in flight.\nS:U - The corruption stays within the kernel\u0027s own memory and security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Freeing an `xdp_frame` as an `sk_buff` makes the kernel interpret ~200 bytes of packet headroom as sk_buff fields and returns a driver-owned page into `skbuff_cache`, so subsequent skb allocations can alias attacker-visible network buffers, yielding kernel memory disclosure.\nI:H - This is a full type confusion: `consume_skb()` performs a refcount decrement through a bogus `_skb_refdst`, an indirect call through `skb-\u003edestructor`, page puts from a fabricated `skb_shinfo`, and a `kmem_cache_free()` of a non-slab pointer, giving heap-corruption and control-flow-hijack primitives with attacker-influenced field values.\nA:H - The commit itself states the incorrect frees lead to crashes on VF reset; slab corruption and wild pointer dereferences reliably produce a kernel oops or panic."
