| In the Linux kernel, the following vulnerability has been resolved:
net: psp: do not inherit the Rx association on clone
sk->psp_assoc sits past sk_dontcopy_end, so sock_copy() copies it into
every socket accepted from a listener without taking a reference, while
inet_sock_destruct() puts for every inet socket. psp_twsk_init() does
refcount_inc() for the timewait socket, so a child closing through
TIME_WAIT cancels its own put and leaves the association with one
reference and N timewait sockets holding the same pointer. Closing the
listener frees it, and the timewait timers then put freed memory.
Rejecting the association on a listening socket is not sufficient: a socket
can acquire one while established and then be turned back into a listener,
because tcp_disconnect() leaves sk->psp_assoc in place.

| In the Linux kernel, the following vulnerability has been resolved:
sched_ext: Fix stall when a task enqueued with SCX_ENQ_LAST lands back on its CPU's local DSQ
With SCX_OPS_ENQ_LAST, the last runnable task on a CPU is passed to
ops.enqueue() instead of being kept running. Exiting tasks without
SCX_OPS_ENQ_EXITING, migration disabled tasks without
SCX_OPS_ENQ_MIGRATION_DISABLED and tasks on an offline rq skip ops.enqueue()
and go straight to the local DSQ. This happens in put_prev_task_scx() after
the pick has settled on idle, so nothing reschedules the CPU, which idles
with the task queued until an unrelated wakeup lands on it or the watchdog
fires.
scx_mitosis, which sets SCX_OPS_ENQ_LAST without SCX_OPS_ENQ_EXITING, hit
this during mass cgroup teardown: exiting tasks stuck in exit_mmap() for
over 40 seconds.
A task put on the local DSQ runs, as anywhere else. If the SCX_ENQ_LAST
enqueue left the task on this CPU's local DSQ, set need_resched on the task
being switched in, as proxy_resched_idle() does. resched_curr() would flag
the task being put instead, and __schedule() clears that right after the
pick. |
| NVIDIA TensorRT-LLM for any platform contains a vulnerability in KvCacheAwareRouter tokenizer loading, where an attacker could cause inclusion of functionality from an untrusted control sphere. A successful exploit might lead to code execution, information disclosure, data tampering, and denial of service. |
| vLLM from 0.7.3 before 0.31.0 forwards the request-supplied mm_processor_kwargs.code_revision to Transformers AutoProcessor.from_pretrained, letting clients select which revision of a model's dynamic processor code is imported when trust_remote_code is enabled. An attacker controlling a revision in the served model repository can send a multimodal request to the unauthenticated /tokenize endpoint to execute arbitrary Python in the vLLM API process. |

| When Thunderbird asked for a security device password (for example a smartcard PIN or the Primary Password) while decrypting an S/MIME message, the message load could finish or be cancelled while the prompt was open. This freed the message decoder while it was still in use, causing a use-after-free and a potentially exploitable crash. This vulnerability was fixed in Thunderbird 158.0.1 and Thunderbird 153.6. |

| In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: fix P2P device removal race in brcmf_detach()
When the driver is removed while the user space process that created
the P2P device (e.g. wpa_supplicant) is still exiting, the P2P device
interface is removed twice and the kernel crashes.
The two paths are:
- wpa_supplicant, on exit, sends NL80211_CMD_DEL_INTERFACE for the P2P
device. nl80211_del_interface() holds RTNL and the wiphy mutex and
calls brcmf_p2p_del_vif(), which disables discovery and waits up to
1.5 s for BRCMF_E_IF_DEL. Then it calls brcmf_remove_interface(),
which unregisters the wdev and frees the vif and the ifp.
- brcmf_detach() sets the bus down, so BRCMF_E_IF_DEL never arrives,
and calls brcmf_remove_interface(ifp, false) for the same ifp.
brcmf_p2p_ifp_removed() reads ifp->vif and then blocks on
rtnl_lock(). When brcmf_p2p_del_vif() releases RTNL, it calls
cfg80211_unregister_wdev() on the wdev that was already unregistered
and freed.
The second list_del_rcu() of wdev->list faults on LIST_POISON2:
brcmfmac: brcmf_p2p_del_vif delete P2P vif
brcmfmac: brcmf_p2p_deinit_discovery enter

The log was taken with debug=0x406 on an i.MX 8M Plus board with a
CYW55513 (Sona IF513) on SDIO. The driver is the Ezurio backport of
brcmfmac from v6.18.22 on a 5.4-rt kernel. The code involved is the same
in mainline.
To reproduce:
1. Start wpa_supplicant on wlan0 and let it associate. It creates the
P2P device (iw dev shows "type P2P-device").
2. Stop wpa_supplicant and remove the driver without waiting for
wpa_supplicant to exit:
kill $(pidof wpa_supplicant)
rmmod brcmfmac_cyw brcmfmac
The crash is reproducible on that board.
For the interface without a netdev (the P2P device), take RTNL and the
wiphy mutex in brcmf_detach() before reading iflist, and remove it with
locked=true. If brcmf_p2p_del_vif() runs first, brcmf_detach() finds the
slot empty. If brcmf_detach() runs first, nl80211 does not find the wdev
any more. The interfaces with a netdev are removed as before, because
brcmf_del_if() takes RTNL on its own for the primary interface. |
| In the Linux kernel, the following vulnerability has been resolved:
tipc: hold a reference to nodes found by link name
tipc_node_find_by_name() returns a node after dropping its RCU read lock
without taking a reference. The LINK_SET, LINK_GET and LINK_RESET_STATS
handlers then lock and access the node, racing with timer-driven cleanup of
a down peer. Generic netlink serialization does not exclude the node
timer.
The following interleaving can leave a handler using a freed node:
CPU 0: find the node under RCU and release the node read lock
CPU 1: tipc_node_timeout() clears the links and unlinks the down node
CPU 1: drop the list and timer references, queuing tipc_node_free()
CPU 0: leave the RCU read-side critical section
CPU 1: complete the grace period and free the node
CPU 0: acquire the node lock through the stale pointer
LINK_SET also uses the node's media address after releasing the node lock,
when passing queued packets to tipc_bearer_xmit().

| PHP has various global state that temporarily points into request memory. In some scenarios, global state may not be correctly reset, or may be repopulated after being reset. The global state may then refer to request memory even after it has been freed. Subsequent requests may read or branch on this stale state before it is fully initialized. Multiple strategies can trigger this condition and produce remote code execution (RCE). |
| In the Linux kernel, the following vulnerability has been resolved:
usb: dwc2: Fix use after free in debug code
We're not allowed to dereference "urb" after calling
usb_hcd_giveback_urb() so save the urb->status ahead of time. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv6: exthdrs: refresh nh after handling HAO option
ip6_parse_tlv() caches skb_network_header(skb) in nh while walking
IPv6 TLVs.
ipv6_dest_hao() may call pskb_expand_head() for a cloned skb, which can
move the skb head and invalidate the cached network header pointer.
Refresh nh after ipv6_dest_hao() returns so any trailing padding or TLVs
are parsed from the current skb head.
This matches the existing pattern used in ip6_parse_tlv() after helpers
that can modify skb header storage. |
| In the Linux kernel, the following vulnerability has been resolved:
net: bridge: remove stale rcu_barrier() in br_multicast_dev_del()
This rcu_barrier() came from a time call_rcu() calls were used in
net/bridge/br_multicast.c.
Now kfree_rcu() is there, we can remove this problematic rcu_barrier()
which causes extreme RTNL pressure in many syzbot reports.

net/mlx5: HWS, Handle destroying table that has a miss table
If a table has a miss table that was created by
'mlx5hws_table_set_default_miss' API function, its miss_tbl
keeps the table that points to it in a list.
If such table is deleted, we need to also remove it from the
miss_tbl list, otherwise the node in miss_tbl list will contain
garbage. |
| In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Keep the domain reference while processing hotplug
We process hotplug events in a workqueue that may run after the domain
has been removed by tb_domain_remove(). For example if user unloads the
driver while at the same time plugging a device router we may have
scheduled tb_handle_hotplug() to run. Avoid possible UAF in this case by
taking the domain reference before scheduling the hotplug handler in
tb_queue_hotplug(). |
