| In the Linux kernel, the following vulnerability has been resolved:
ipv6: flowlabel: cap duplicate leases per socket
ipv6_flowlabel_get() allocates an ipv6_fl_socklist entry for every
successful GET. The recheck path for a compatible existing flowlabel
links another lease without applying any lease admission check. Repeated
GET requests for one shareable label can therefore grow a socket's lease
list without bound.
Reject a new unprivileged lease once the socket already holds
FL_MAX_PER_SOCK leases. Check this on the shared recheck path so reuse
of a globally interned label, including the fl_intern() collision path,
is covered as well. New-label admission remains under the existing
mem_check() policy.
Use capable(CAP_NET_ADMIN) rather than ns_capable(), matching
mem_check(). An unprivileged user must not bypass the cap by creating a
user namespace and a netns where they have CAP_NET_ADMIN, which would
still consume host memory.
Check the capability only when the socket reaches the limit, so
successful unprivileged GET requests below the cap do not generate a
capability audit. Do the admission check before updating linger and
expires so a rejected GET does not refresh the shared label, matching
the existing socket-list allocation failure path. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv4: fib: bound automatic table ID allocation
fib_empty_table() probes every table ID from 1 until it finds a
free one. IPv4 tables are stored in a 256-bucket hash table, so a
dense set of IDs makes each probe walk a growing hash chain while
RTNL is held.
Automatic table assignment ("ip rule ... table 0") is an IPv4-only
legacy path. Bound the automatically allocated ID to 4096 so the
RTNL hold stays bounded, without changing lookups of explicitly
specified table IDs.
This changes user-visible behavior. A table-0 rule previously
received the lowest free ID in 1..RT_TABLE_MAX (0xFFFFFFFF). After
this patch the search stops at 4096 and the rule add fails with
ENOBUFS if that range is fully occupied. Explicit table IDs above
4096 remain usable.
The automatic path is unused in practice: it is IPv4-only, not
documented by ip-rule, uncovered by kernel selftests, and both
NetworkManager and systemd refuse table 0. |
| In the Linux kernel, the following vulnerability has been resolved:
ieee802154: hwsim: serialize pib updates to fix double-free
hwsim_update_pib() does an unserialized read-swap-free of phy->pib:
pib_old = rtnl_dereference(phy->pib);
...
rcu_assign_pointer(phy->pib, pib);
kfree_rcu(pib_old, rcu);
It assumes the RTNL is held, but ->set_channel is not always called
under it: the mac802154 scan worker changes channels via
drv_set_channel() without the RTNL. Such an update can race an
RTNL-held one on the same phy; both read the same pib_old and both
kfree_rcu() it, double-freeing the object. With SLUB percpu sheaves
batching kfree_rcu(), this surfaces as a KASAN invalid-free in
rcu_free_sheaf().
struct hwsim_phy has no lock for pib. Add one and make the swap atomic
with rcu_replace_pointer() under it, dropping the misleading
rtnl_dereference(). |
| In the Linux kernel, the following vulnerability has been resolved:
ieee802154: cc2520: fix FIFOP work use-after-free
The FIFOP interrupt handler queues cc2520_fifop_irqwork. On removal,
cc2520_remove() only flushes the work. The devm-managed FIFOP IRQ
remains active until after ->remove() returns and can queue the work
again after that flush, allowing it to run after the private data is
released.
Disable the work with disable_work_sync() instead of flushing it, so
the handler can no longer queue it once removal begins. Destroy the
buffer mutex last, since the worker and the stop callback invoked
through ieee802154_unregister_hw() both take it.

| In the Linux kernel, the following vulnerability has been resolved:
idpf: disable DIM work before freeing q_vectors
idpf never drains the Tx/Rx DIM works before freeing the memory they
live in. tx_dim and rx_dim are embedded in struct idpf_q_vector, they
are queued from the NAPI poll via net_dim(), and idpf_vport_intr_rel()
ends with kfree(rsrc->q_vectors). Nothing in the driver cancels them.
idpf_tx_dim_work() and idpf_rx_dim_work() then run on freed memory:
idpf_vport_intr_write_itr() writes the ITR register through
q_vector->intr_reg.tx_itr / rx_itr, void __iomem pointers loaded out of
the freed q_vector. No configuration is needed to get there --
IDPF_ITR_IS_DYNAMIC() is defined as (itr_mode) and idpf_vport_alloc()
initialises both modes to IDPF_ITR_DYNAMIC.
Draining after idpf_vport_intr_napi_dis_all() is not enough on its own.
idpf_net_dim() is called from inside the
"if (napi_complete_done(napi, work_done))" branch of the poll, and
napi_complete_done() has already cleared NAPIF_STATE_SCHED by then.
napi_disable_locked() waits only while (val & (NAPIF_STATE_SCHED |
NAPIF_STATE_NPSVC)), so napi_disable() can return while the poll tail is
still queueing the work, and a plain cancel_work_sync() would be
re-armed behind the drain.
Use disable_work_sync(): schedule_work() on a work with a non-zero
disable count is dropped by clear_pending_if_disabled() before
__queue_work() is reached.
Move idpf_init_dim() to idpf_vport_intr_alloc() so the works are
initialised on every path that can reach the drain -- the three
"goto intr_deinit" sites between idpf_vport_intr_init() and
idpf_vport_intr_ena() get there without the enable side having run.
Nothing re-enables them: rsrc->q_vectors is freed on every exit from
idpf_vport_open() and on every idpf_vport_stop(), so the count dies with
the object.
It is a race, not a deterministic failure -- net_dim() only schedules
once DIM_NEVENTS events have accumulated and the profile index changes.
A KASAN ifup/ifdown loop under load is the way to see it. |
| In the Linux kernel, the following vulnerability has been resolved:
vdpa: ifcvf: Put device on unsupported feature error
Route unsupported provisioned features through the common error path after
vdpa_alloc_device() so the allocated device and adapter pointer are
released consistently. |
| The Onion module in AIL Framework contained a performance shortcut in its URL extraction logic that accepted URLs as valid .onion targets based solely on a length check (exactly 69 characters) and a suffix check (ending in ".onion"), without performing proper hostname parsing or onion-domain validation. An unauthenticated attacker who could publish or control web content crawled by the framework could embed a crafted URL containing an IP address or non-onion hostname with a path ending in ".onion" that satisfied the length and suffix conditions. Such a URL would be extracted, its domain naively sliced from the string, and queued as a legitimate onion crawler task. This allowed unauthenticated content publishers to inject arbitrary non-onion targets into the crawler's task queue, influencing crawler behavior and potentially directing it toward unintended network resources. The vulnerability required no authentication, no user interaction, and only the ability to place crafted content in a location the framework would crawl. The security impact is a loss of integrity in the crawler's target selection: the framework processes and acts upon URLs that do not correspond to legitimate .onion services. |

| The AIL Framework crawler task creation API (api_add_crawler_task) contained an insufficient authorization check when a user supplied a cookiejar UUID to attach to a one-shot or scheduled crawler task. The original code only verified that the cookiejar existed and, if its access level was 0, compared the cookiejar's owning user ID to the requesting user ID. It did not validate organizational boundaries, did not account for the requesting user's role. When the cookiejar level was not 0, no access check was performed at all. An authenticated user could therefore reference another organization's cookiejar by UUID and have the crawler use that organization's stored cookies (session tokens, authentication credentials) when performing web crawls, effectively leaking or exfiltrating the victim organization's session data.
The vulnerability requires an authenticated user with the ability to create crawler tasks. The attacker must know or guess a valid cookiejar UUID belonging to another organization. The impact is unauthorized access to another organization's stored cookies and session data through the crawler infrastructure. |

| Moquette is a lightweight Java MQTT broker. Prior to 0.18.1, when pattern-based ACL rules are configured, AuthorizationsCollector.canDoOperation substitutes client ID and username values directly into rules containing %c or %u and then treats the result as an MQTT topic filter. A client that uses + or # in either identity can broaden the substituted filter and gain cross-tenant read and write access. A # identity can also produce an invalid filter that triggers a NullPointerException in Topic.match and disrupts session processing. This issue is fixed in version 0.18.1. |
