| Apache Traffic Server's experimental wasm plugin has a use-after-free in its transaction-close handler and forwards unvalidated guest-supplied metric IDs to the internal stats API.
This issue affects Apache Traffic Server: from 10.0.0 through 10.1.4, 10.2.0.
Users are recommended to upgrade to version 10.1.5 or 10.2.1, which fix the issue. |

| In the Linux kernel, the following vulnerability has been resolved:
usb: typec: ucsi: glink: fix use-after-free of ucsi on remove
The pmic_glink client is released by the devres cleanup, which runs
after pmic_glink_ucsi_remove() has returned, so its notification
callbacks can queue work until then. Work that runs after
ucsi_unregister() has been called touches freed state: it dereferences
the connector array that ucsi_unregister() freed, or registers and
unregisters the instance a second time.
Disable both work items with disable_work_sync() before unregistering,
and unregister only if the instance is still registered.
This issue was found by an in-house static analysis tool. |

EDAC/altera: Drop __init from ECC setup paths for re-probe safety
Sashiko reports:
"Does suppressing sysfs unbinding fully prevent the execution of freed __init
memory? If altr_sysmgr_regmap_lookup_by_phandle() returns -EPROBE_DEFER, the
probe is deferred until after __init memory is freed."
The a10 EDAC .setup callbacks (sdmmc, ethernet, nand, dma, usb, qspi) and
their helpers (altr_init_a10_ecc_device_type, altr_init_a10_ecc_block) were
marked __init. These run from the probe path, which may execute after init
memory is freed -- e.g. a probe deferred via -EPROBE_DEFER that only succeeds
once a late/module dependency appears, or a manual unbind/rebind. Calling
__init code then dereferences freed memory. Remove __init so these functions
remain valid at runtime. |

drm/xe/i2c: cancel the client work on remove
xe_i2c_notifier() stores the DesignWare adapter in i2c->adapter and
schedules i2c->work when the adapter is registered under the xe I2C
platform device, and xe_i2c_client_work() then instantiates the AMC
client device on that adapter.
xe_i2c_remove() tears down the AMC, unregisters the client devices,
the bus notifier and the adapter platform device, but it never drains
i2c->work. A work item that is still queued or running when the
adapter is unregistered dereferences i2c->adapter in
i2c_new_client_device() after platform_device_unregister() has
released the adapter. The work item is also embedded in the
devm-allocated struct xe_i2c, so a work item still queued after the
drm device devm unwind frees that allocation runs its callback on
freed memory.
The bus notifier is the only thing that schedules this work, and it is
unregistered after the client devices. An instance that is still queued
when the teardown runs can therefore write
i2c->client[XE_I2C_CLIENT_AMC] while the loop is unregistering and
clearing the same array, and an AMC client it instantiates late is only
cleaned up by the adapter's own child sweep in i2c_del_adapter().
Move bus_unregister_notifier() in front of the client teardown loop
and cancel the work right after it, so no new instance can be
scheduled and a queued instance is drained before the client array is
touched. A running instance still finds a live adapter, since the
adapter is unregistered later.

| In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tipd: fix uninitialized typec_partner_desc in cd321x_update_work()
cd321x_update_work() passes a stack-allocated typec_partner_desc to
typec_register_partner() after initializing only usb_pd, accessory and
identity.
typec_register_partner() copies attach and deattach from the descriptor
into the partner. With those fields left unset, garbage function pointers
may be stored and later invoked from typec_partner_link_device() when a USB
device is linked to the port. Uninitialized pd_revision and usb_capability
similarly leak stack data through partner sysfs.
Zero-initialize the descriptor so optional callbacks remain NULL and the
remaining fields are zero. |

Bluetooth: ISO: fix refcounting of iso_conn
iso_conn_del() and iso_chan_del() have a race that results to double-put
of iso_conn:
[Task hdev->workqueue] [Task 2]
iso_conn_del iso_chan_del
iso_conn_hold_unless_zero iso_conn_lock
iso_conn_lock conn->sk = NULL
iso_conn_unlock
sk = iso_sock_hold(conn) <---------ยด
if (!sk) iso_conn_put iso_conn_put
iso_conn_put /* UAF */
The extra put for !sk in iso_conn_del() is currently required since
failing iso_chan_add() may leave iso_conn not associated with any sk.
Fix by having iso_pi(sk)->conn own refcount when non-NULL, so
iso_conn_del does not need to put it. Adjust the iso_conn_add()
refcounting so that conn is put if it does not get associated with an
sk. |

KVM: arm64: vgic: Take a refcount on IRQs referenced by last_lr_irq
Referencing the last interrupt inserted in an LR is rather fragile, as
this interrupt can vanish if a concurrently unmapped LPI.
Solve this by bumping up the refcount on the interrupt when populating
last_lr_irq, and drop it at vgic_prune_ap_list() time, when LPIs are
being reclaimed. |

nfc: fix use-after-free in nfc_get_local_general_bytes
Commit 6709d4b7bc2e ("net: nfc: Fix use-after-free caused by
nfc_llcp_find_local") attempted to fix a use-after-free (UAF) issue by
invoking nfc_llcp_local_put(local) after accessing local->gb. However,
if the reference count drops to zero, local is freed immediately,
leading to a use-after-free when callers access the returned pointer.
Alternative approaches using dynamic allocation (e.g. kmemdup) introduced
memory leaks because callers consistently treat the returned pointer as
borrowed memory.
Fix this properly by refactoring nfc_llcp_general_bytes() and
nfc_get_local_general_bytes() to accept a caller-provided output buffer
(out_gb) and its maximum length (gb_max_len). The general bytes are
safely copied into out_gb before calling nfc_llcp_local_put(local),
ensuring safe lifetime management without ownership transfer complications.
Update all callers across drivers (microread, pn533, pn544, st21nfca,
digital_dep, and nci) to provide their own destination buffers and pass
them to nfc_get_local_general_bytes(). |
| In the Linux kernel, the following vulnerability has been resolved:
drm/virtio: release the GEM object on virtio_gpu_vram_create() errors
virtio_gpu_vram_create() frees the object with a bare kfree(vram) on
both error paths after drm_gem_private_object_init() has run, and on the
second one after drm_gem_create_mmap_offset() has linked obj->vma_node
into the device's VMA offset manager. The freed object stays in that
interval tree, so a later lookup or insertion walks freed memory, and
the dma_resv and gpuva lock are never destroyed.
Call drm_gem_object_release() before kfree() on both paths. |

eth: fbnic: use the Rx queue napi pointer to find the napi vector
The queue management ndos pick the napi vector for an Rx queue with:
nv = fbn->napi[idx % fbn->num_napi];
The issue is this is only correct in the cases where there are no
standalone Tx vectors. In those cases we were allocating the Tx vectors
first and then the Rx so the queues would be pointing to Tx NAPI vectors
instead of the Rx ones.
The mapping the ndos want is already recorded. fbnic_set_netif_napi()
publishes it with netif_queue_set_napi(), which stores the napi pointer
in netdev_rx_queue.napi, and fbnic_reset_netif_napi() clears it again.
Both run under the netdev instance lock that the queue management ndos
also hold, so the pointer can be read directly.
Use it and drop the divide. The pointer is NULL exactly while the
datapath is down, so fbnic_queue_mem_alloc() can reject that case rather
than reaching into freed state: netdev_rx_queue_restart() calls it
before it tests netif_running(), and fbnic_pm_suspend() leaves
netif_running() true across a PCIe recovery that never completes, so a
queue restart can arrive after fbnic_stop() has freed the rings and the
vectors. fbnic_stop() clears the association in
fbnic_reset_netif_queues() before fbnic_free_napi_vectors(), so the
NULL is always published first. fbnic_queue_start() and
fbnic_queue_stop() need no check of their own, as
netdev_rx_queue_reconfig() only reaches them once fbnic_queue_mem_alloc()
has succeeded under the same instance lock. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: flowtable: publish HW_DEAD after worker is done
flow_offload_work_del() sets NF_FLOW_HW_DEAD before the work handler
clears NF_FLOW_HW_PENDING. Once a flow is both HW_DYING and HW_DEAD, a
concurrent garbage collection pass can remove it and schedule it for RCU
freeing.
The offload worker holds neither an RCU read lock nor a reference to the
flow. If it is preempted after publishing HW_DEAD, the RCU callback can
free the flow before the worker resumes and clears HW_PENDING, resulting
in a use-after-free.
Move HW_DEAD publication to the common worker epilogue after the pending
bit is cleared, making it the final flow access by destroy work. Order all
preceding flow accesses before publishing the bit that allows garbage
collection to free the object. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: frequency: adf4377: Fully initialize clk_init_data and clk_parent_data
The clk_init_data structure contains several mutually-exclusive members
for different methods to specify the possible parents of a clock,
prompting drivers to initialize only the members they need. However,
not initializing all members may cause subtle issues, which are only
exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is
enabled.
adf4377_clk_register() fills in init.parent_data, and assumes that
init.parent_names is NULL. However, the latter is uninitialized, and
thus may cause a crash.
Similarly, adf4377_clk_register() fills in only parent_data.fw_name,
leaving other members of the clk_parent_data structure uninitialized.
Make sure all members are fully initialized, to fix such bugs, and to
avoid future breakage when converting drivers to a different method for
specifying the parents. |
