| An issue was discovered in MFC in Samsung Mobile Processor and Wearable Processor Exynos 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 1580, 2500, 2600, 1680, W920, W930, and W1000. A double-free vulnerability in the Exynos MFC encoder driver (due to improper cleanup of dma_buf references during error handling) leads to kernel memory corruption and potential arbitrary code execution. |
| PRTG Network Monitor before 23.1.82 allows remote attackers to write to files via the FTP Server Count Sensor. |
| An issue was discovered in Softing OPC UA C++ SDK through 6.20 and Softing Secure Integration Server through 1.22. By using FileType renames, it is possible to bypass limitations on assignment of a directory path to FileDirectory OPC UA objects and a file path to File OPC UA objects. |
| Portable Puzzle Collection before 20230116.5782e29 was discovered to contain a buffer overflow which is triggered when an unusually long move is executed. |
| An issue was discovered in DPU in Samsung Mobile Processor Exynos 1280, 2200, 1380, 1480, 2400, 1580, 2500, 1680, and 2600. A double-free vulnerability in the Samsung Exynos DPU driver (due to improper pointer management during DMA buffer reallocation) leads to kernel memory corruption and a potential use-after-free. |
| An issue was discovered in DPU in Samsung Mobile Processor Exynos 1280, 2200, and 1380. A heap overflow in the Exynos DRM HDR driver (due to improper buffer size validation) leads to kernel memory corruption and a system crash. |
| An issue was discovered in camera in Samsung Mobile Processor Exynos 1330, 1380, 1480, 2400, 1580, and 2500. Sending a malformed message to the test_msg sysfs entry causes an out-of-bounds write, leading to denial of service. |
| An issue was discovered in CustOS Driver in Samsung Mobile Processor Exynos 1580. Requesting oversized shared memory from the custos_iwc device enables out-of-bounds read and write, potentially leading to memory corruption or information leakage. |
| An issue was discovered in DPU in Samsung Mobile Processor Exynos 1280, 2200, 1380, 1480, 2400, 1580, 2500, 1680, and 2600. A TOCTOU race condition in the Exynos DRM HDR Driver leads to a heap overflow, causing a kernel crash. |
| In the Linux kernel, the following vulnerability has been resolved:
sctp: fix NULL deref on untransmitted RECONF completion
sctp_process_strreset_outreq(), sctp_process_strreset_addstrm_out() and
sctp_process_strreset_resp() complete a pending stream reconfiguration
request by stopping the reconf timer on the transport it was sent on:
t = asoc->strreset_chunk->transport;
if (timer_delete(&t->reconf_timer))
sctp_transport_put(t);
chunk->transport is assigned by __sctp_packet_append_chunk() when the
chunk is appended to an outbound packet, and sctp_outq_flush_ctrl() arms
the reconf timer at that same point. A request already published in
asoc->strreset_chunk but not yet transmitted has neither, so completing
it dereferences NULL.
Two ways to get there. sctp_send_asconf_del_ip() sets
asoc->src_out_of_asoc_ok without sending anything when the address being
removed is the association's last one, and sctp_outq_flush_ctrl() then
leaves every non-ASCONF control chunk queued; as only
sctp_process_asconf_ack() clears that flag, it persists. An unprivileged
process that removes such an address and then asks for a stream reset
panics the kernel from softirq. A peer needs neither ASCONF nor local
help: sctp_cmd_interpreter() uncorks the outqueue only once the whole
packet has been processed, so a reply built while walking a RECONF chunk
stays untransmitted for the rest of that walk, and one RECONF chunk
carrying [Incoming SSN Reset Request, Outgoing SSN Reset Request,
Response] -- or two RECONF chunks in one packet -- reaches the same
dereference.

A response can only acknowledge a request that was actually sent, so do
not match asoc->strreset_chunk while chunk->transport is NULL. Guarding
the lookup covers all three completion sites. |
| In the Linux kernel, the following vulnerability has been resolved:
sctp: fix stream->outcnt underflow on duplicate RECONF responses
A cached RECONF chunk may contain more than one request parameter. A
duplicate response can therefore find and process the same ADD_OUT request
again while another parameter is still outstanding, rolling back outcnt
twice and possibly underflowing it.
Track outstanding request types as bits and clear each bit after its first
response. Later responses for the same request are then ignored. |
| In the Linux kernel, the following vulnerability has been resolved:
power: supply: bq24257: fix use-after-free on remove
The STAT-pin interrupt is devm-managed, so it stays armed until the devm
cleanup that runs after remove() returns. remove() cancels
bq->iilimit_setup_work while the threaded handler can still fire; that
handler reschedules the work and dereferences bq, so the work runs
against freed memory once devm frees bq.
Make the delayed work device-managed with devm_delayed_work_autocancel(),
registered before the interrupt request. The devm cleanup then releases
the interrupt first, so the handler can no longer reschedule the work,
and cancels the work before bq is freed. The explicit
cancel_delayed_work_sync() in remove() is no longer needed and is dropped.
Found by static analysis. |
| A security flaw has been discovered in vllm-project vLLM up to 0.29.0. The affected element is the function TiktokenTokenizer::new of the file rust/src/text/src/backend/hf/mod.rs of the component tiktoken vocab File Handler. The manipulation results in denial of service. The attack is only possible with local access. The exploit has been released to the public and may be used for attacks. The pull request to fix this issue awaits acceptance. |
| In the Linux kernel, the following vulnerability has been resolved:
power: supply: bq256xx: drain usb_work before freeing the charger
The USB-PHY notifier queues usb_work, whose handler calls
power_supply_changed(bq->charger). The reset devm action only unregisters
the notifier and was registered before the power supplies, so devm frees
bq->charger on unwind before the action runs; a usb_work still queued can
then dereference it.
Register the reset action after the power supplies, so it unregisters
the notifiers and drains usb_work before the supplies are released.
Initialize usb_work and obtain the PHY references before registering
the notifiers, so the worker cannot run before the supplies exist.
Found by static analysis. |
| In the Linux kernel, the following vulnerability has been resolved:
power: supply: bq25890: Fix power_supply reference leak
bq25890_fw_probe() acquires a reference to a secondary charger using
power_supply_get_by_name(), but the reference is not released on later
probe failures or on driver detach.
In particular, failures after bq25890_fw_probe() returns successfully,
such as a failure in bq25890_hw_init(), also leak the reference.
Register a device-managed cleanup action immediately after acquiring
the secondary charger. This releases the reference on all subsequent
probe failures and on driver detach.
Found by code review. |
| In the Linux kernel, the following vulnerability has been resolved:
power: supply: cros_usbpd-charger: bound the EC-reported port count
cros_usbpd_charger_probe() reads two port counts from the EC and uses
one of them, num_charger_ports, as the loop bound when populating a
fixed-size array:
struct port_data *ports[EC_USB_PD_MAX_PORTS]; /* 8 entries */
...
for (i = 0; i < charger->num_charger_ports; i++)
charger->ports[charger->num_registered_psy++] = port;
Both num_usbpd_ports (from EC_CMD_USB_PD_PORTS) and num_charger_ports
(from EC_CMD_CHARGE_PORT_COUNT) are u8 values reported by the EC. The
only validation is a sanity check that compares the two EC-reported
values against each other:
if (num_charger_ports < num_usbpd_ports ||
num_charger_ports > num_usbpd_ports + 1)
return -EPROTO;
It never checks either count against EC_USB_PD_MAX_PORTS, the size of
the ports[] array. A malfunctioning, malicious or compromised EC that
reports num_usbpd_ports == num_charger_ports == N for any N > 8 (for
example both 255) passes this check, and the loop then writes N pointers
into the 8-entry ports[] array embedded in the devm_kzalloc()'d
charger_data, overflowing it by up to 255 - 8 = 247 entries (~1976
bytes): a slab out-of-bounds write.
Reject a port count larger than the ports[] array can hold. |
| In the Linux kernel, the following vulnerability has been resolved:
power: supply: cros_usbpd: Limit port counts to EC_USB_PD_MAX_PORTS
Currently the cros_usbpd-charger driver probe iterates based on raw
charger port count returned by the embedded controller. The only check
is against the number of USB PD ports which the embedded controller
also defines. A malicious embedded controller could return an inaccurate
port count (up to 255) resulting in an out of bounds write and
subsequent memory corruption.
Update helper functions in cros_usbpd-charger to limit port counts to
EC_USB_PD_MAX_PORTS. |
| In the Linux kernel, the following vulnerability has been resolved:
power: supply: lp8727: fix use-after-free in lp8727_release_irq()
lp8727_isr_func(), the threaded IRQ handler, is the only caller that arms
pchg->work via schedule_delayed_work(). lp8727_release_irq() currently
cancels the work before freeing the IRQ, so an IRQ delivered in between
can re-arm the work through the threaded handler. After .remove returns
the devm layer frees pchg while lp8727_delayed_func() may still run and
dereference it.
Free the IRQ first so the threaded handler is quiesced and can no longer
queue work, then cancel the delayed work to drain the final generation.
This issue was found by an in-house static analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
power: supply: qcom_battmgr: terminate the strings from firmware
The qcom_battmgr_sc8280xp_strcpy() takes a Pascal-style string when the
firmware sends one. Otherwise it copies all BATTMGR_STRING_LEN bytes and
leaves the destination without a terminator.
Those destinations are model_number, serial_number and oem_info, each
BATTMGR_STRING_LEN and declared next to each other. They go out to user
space as val->strval, which power_supply_format_property() prints with
"%s", so a firmware string that fills the whole field makes that read run
into the following members.
Use strscpy() so the copy always terminates, the way the SM8350 path
already does for the same field. |
| In the Linux kernel, the following vulnerability has been resolved:
power: supply: rt9455: quiesce delayed work before teardown
The threaded IRQ handler can queue pwr_rdy_work,
max_charging_time_work and batt_presence_work. pwr_rdy_work and
batt_presence_work can also queue max_charging_time_work, while
batt_presence_work can requeue itself.
rt9455_remove() cancels max_charging_time_work before
batt_presence_work. The latter can therefore queue
max_charging_time_work after it has already been cancelled:
rt9455_remove() workqueue
cancel pwr_rdy_work
cancel max_charging_time_work
batt_presence_work queues
max_charging_time_work
cancel batt_presence_work
return
devres frees rt9455_info
max_charging_time_work dereferences
rt9455_info
The IRQ also remains registered until devres cleanup and can queue more
work after any of the cancellation calls. If rt9455_hw_init() fails
after the IRQ has been requested, probe returns without cancelling work
that may already have been queued. A pending callback can then access
rt9455_info after it has been freed.
Register rt9455_cancel_all_delayed_works() through
devm_add_action_or_reset() right after devm_power_supply_register().
devres invokes the action in reverse registration order, after the
managed IRQ has been freed and before rt9455_info is released, so the
delayed works are drained in both rt9455_remove() and the probe error
path. Cancel pwr_rdy_work and batt_presence_work before
max_charging_time_work because both can queue the latter.
