| In the Linux kernel, the following vulnerability has been resolved:
xhci: Prevent queuing new commands if xhci is inaccessible
Refuse to queue a new command on the command ring if xHC is marked
inaccessible with the HCD_FLAG_HW_ACCESSIBLE.
HCD_FLAG_HW_ACCESSIBLE is set and cleared in suspend and resume.
Also print a warning if xhci is being suspended with commands
still pending on the command ring. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Avoid DPMS-on for phantom stream
[Why & How]
Calling dc_update_planes_and_stream separately for stream and its
phantom stream causes a NULL pointer dereference, since the phantom is
destroyed on the first call.
Skip the call for phantom streams. |
| In the Linux kernel, the following vulnerability has been resolved:
ata: ahci: fail probe if BAR too small for claimed ports
When an AHCI controller is disabled in BIOS, its HOST_CAP register may
contain a bogus value, e.g. 0xFFFFFFFF.
Since CAP.NP (Number of Ports) is a zeroes based 5-bit register field,
a value of 0x1f means 32 ports. If CAP.NP claims more ports than can
physically fit within the mapped BAR region, accessing port registers
beyond the BAR boundary causes a kernel panic.
Add validation in ahci_init_one() to check that the BAR size is
sufficient for the number of ports claimed in CAP.NP. The check
calculates the required MMIO size as:
required_size = 0x100 (global registers) + max_ports * 0x80
If required_size exceeds the actual BAR size, the probe fails with
-ENODEV, preventing the panic and providing a clear error message.

| In the Linux kernel, the following vulnerability has been resolved:
ACPICA: Fix NULL pointer dereference in acpi_ns_custom_package()
acpi_ns_custom_package() unconditionally dereferences the first element
of the package to read the _BIX version number, without checking for
NULL:
if ((*Elements)->Common.Type != ACPI_TYPE_INTEGER)
When firmware returns a _BIX package whose first element is an
unresolvable reference, ACPICA evaluates that entry to NULL.
acpi_ns_remove_null_elements() does not strip NULL entries for
ACPI_PTYPE_CUSTOM packages (fixed-position format would break if
elements were shifted), so acpi_ns_custom_package() sees the NULL
and causes a crash.
Add a NULL check for the first element (version field) before
dereferencing it. The caller then receives AE_AML_OPERAND_TYPE
instead of crashing. |
| CuteNews v.2.1.2 is vulnerable to Server-Side Request Forgery (SSRF) in core/modules/media.php -- upload_from_inet (Media Manager's "Upload by URL" functionality). |
| Stencil core 4.43.5 contains a DOM-based cross-site scripting (XSS) vulnerability in the component runtime. When a downstream application enables the experimental slot fixes option and uses scoped components, assigning a string to the textContent property of such a component's host element causes the value to be parsed as HTML instead of being inserted as text. If an application writes attacker-controlled data to these host elements, the data can be interpreted as markup and script can execute in the context of the application's origin. |

ACPICA: Fix condition check in acpi_ps_parse_loop()
Fix condition check for AML_ELSE_OP in acpi_ps_parse_loop() to prevent
out-of-bounds access. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: goku_udc: avoid NULL deref of dev->driver in INT_USBRESET log
goku_irq() handles a number of bus events under a single ep0 path.
It already guards the gadget driver suspend/resume callbacks against a
NULL ->driver:
if (dev->gadget.speed != USB_SPEED_UNKNOWN
&& dev->driver
&& dev->driver->resume) {
spin_unlock(&dev->lock);
dev->driver->resume(&dev->gadget);
...
}
but the very next branch unconditionally dereferences dev->driver
when an INT_USBRESET arrives:
if (stat & INT_USBRESET) {
ACK(INT_USBRESET);
INFO(dev, "USB reset done, gadget %s\n",
dev->driver->driver.name);
}
If the controller raises INT_USBRESET before any gadget driver has
been bound (or after one has been unbound), dev->driver is NULL and
the printk dereferences NULL.
smatch flags the inconsistency:
drivers/usb/gadget/udc/goku_udc.c:1618 goku_irq() error:
we previously assumed 'dev->driver' could be null (see line 1607)
Fall back to a placeholder when the gadget driver is not bound.
No functional change while a gadget driver is bound. |
| In the Linux kernel, the following vulnerability has been resolved:
i3c: master: svc: Prevent IRQ storm from false SLVSTART on NPCM845
On NPCM845, when a target on the I3C bus gets stuck holding SDA low,
the controller reports a false Master Request (MR) in-band interrupt
event. The driver handles this by emitting a STOP condition to restore
the bus.
However, the hardware quirk SVC_I3C_QUIRK_FALSE_SLVSTART indicates that
emitting a STOP condition may spuriously set the SLVSTART interrupt
status bit. In the Master Request case, this creates a feedback loop:
the STOP triggers a new SLVSTART event, the IRQ handler fires again,
the controller still reports an MR type, another STOP is emitted, and
the cycle repeats indefinitely, resulting in an IRQ storm that can lock
up the CPU.
Clear the SLVSTART status bit explicitly after emitting the STOP in the
Master Request IBI handler when the SVC_I3C_QUIRK_FALSE_SLVSTART quirk
is set. This breaks the feedback loop without affecting normal SLVSTART
processing, which is already guarded in the top-level IRQ handler by
checking that MSTATUS is in SLVREQ state. |
| A remote code execution (RCE) vulnerability in the RemoteRegisterFunctionService function (/remote/remote-register-function.service.ts) of Univer v1.0.0-alpha.2 allows attackers to execute arbitrary code via a crafted payload. |
| In the Linux kernel, the following vulnerability has been resolved:
hsr: broadcast netlink notifications in the device's net namespace
The HSR generic netlink family sets .netnsok = true. HSR devices can
live in network namespaces other than init_net.
Two async notifiers broadcast events with genlmsg_multicast(). They
are hsr_nl_ringerror() and hsr_nl_nodedown(). That helper delivers
only on the default genl socket in init_net. So the events always land
in init_net. The network namespace of the device does not matter.
This has two effects. A listener in the device's own namespace never
sees its own ring error and node down events. A privileged listener in
init_net receives events from HSR devices in other namespaces. The
payload carries the peer node MAC (HSR_A_NODE_ADDR) and the slave port
ifindex (HSR_A_IFINDEX).
Switch both callers to genlmsg_multicast_netns(). Other families with
.netnsok = true already do this. Examples are gtp, ovpn, team,
batman-adv, netdev-genl, ethtool and handshake.
hsr_nl_ringerror() already has the slave port. It uses
dev_net(port->dev). hsr_nl_nodedown() takes the namespace from the
master port via hsr_port_get_hsr(). |

powercap: intel_rapl: Fix memory leak in rapl_add_package_cpuslocked()
When topology_physical_package_id()/topology_logical_die_id() returns
a negative value, rapl_add_package_cpuslocked() returns ERR_PTR(-EINVAL)
directly without freeing the rapl_package structure that was just
allocated by kzalloc_obj(), leaking memory on every failed package
addition.
Use the existing err_free_package label so that the allocation is
released on the error path. |
| In the Linux kernel, the following vulnerability has been resolved:
rds: filter RDS_INFO_* getsockopt by caller's netns
The RDS_INFO_* family of getsockopt(2) options reads several
file-scope global lists that are not per-netns:
rds_sock_info / rds6_sock_info,
rds_sock_inc_info / rds6_sock_inc_info -> rds_sock_list
rds_tcp_tc_info / rds6_tcp_tc_info -> rds_tcp_tc_list
rds_conn_info / rds6_conn_info,
rds_conn_message_info_cmn (for the *_SEND_MESSAGES and
*_RETRANS_MESSAGES variants),
rds_for_each_conn_info (for RDS_INFO_IB_CONNECTIONS)
-> rds_conn_hash[]
The handlers do not filter by the caller's network namespace.
rds_info_getsockopt() has no netns or capable() check, and
rds_create() has no capable() check, so AF_RDS is reachable from
an unprivileged user namespace. As a result, an unprivileged
caller in a fresh user_ns plus netns can read the bound address
and sock inode of every RDS socket on the host, the peer address
of incoming messages on every RDS socket on the host, the peer
address and TCP sequence numbers of every rds-tcp connection on
the host, and the peer address and RDS sequence numbers of every
RDS connection on the host.
The rds-tcp transport is reachable from a non-initial netns (see
rds_set_transport()), so a one-shot init_net gate at
rds_info_getsockopt() would deny legitimate per-netns visibility
to rds-tcp callers. Instead, filter at each handler by comparing
the netns of the caller's socket to the netns of the list entry,
or to rds_conn_net(conn) for connection paths. Only copy entries
whose netns matches the caller. Counters (RDS_INFO_COUNTERS) are
aggregate statistics and remain global.
Reproducer (KASAN VM, rds and rds_tcp loaded): an AF_RDS socket
binds 127.0.0.1:4242 in init_net as root. A child process enters
a fresh user_ns plus netns and opens AF_RDS there, then calls
getsockopt(SOL_RDS, RDS_INFO_SOCKETS). Before this change, the
child sees the init_net socket. After this change, the child
sees zero entries.
Drop the rds_sock_count, rds_tcp_tc_count, and rds6_tcp_tc_count
globals. v2 used them for the size precheck and lens->nr; v3
replaced the precheck with a per-ns count from a first pass over
the list, so the globals have no remaining readers. The matching
increments and decrements in rds_create()/rds_destroy_sock() and
rds_tcp_set_callbacks()/rds_tcp_restore_callbacks() go away with
them. Reported by the kernel test robot under clang W=1. |

driver core: Avoid warning when removing a device while its supplier is unbinding

This warning is triggered when a consumer is removed because the links
status of its supplier is not DL_DEV_DRIVER_BOUND and the link flag
DL_FLAG_SYNC_STATE_ONLY is not set.
The topology in terms of consumers/suppliers used was the following
(consumer ---> supplier):
i2c -----------> OIC ----> PCI device
| ^
| |
+---> pinctrl ---+
When the PCI device is removed, the OIC (interrupt controller) has to be
removed. In order to remove the OIC, pinctrl and i2c need to be removed
and to remove pinctrl, i2c need to be removed. The removal order is:
1) i2c
2) pinctrl
3) OIC
4) PCI device
In details, the removal sequence is the following (with 0000:01:00.0 the
PCI device):
driver_detach: call device_release_driver_internal(0000:01:00.0)...
device_links_busy(0000:01:00.0):
links->status = DL_DEV_UNBINDING
device_links_unbind_consumers(0000:01:00.0):
0000:01:00.0--oic link->status = DL_STATE_SUPPLIER_UNBIND
call device_release_driver_internal(oic)...
device_links_busy(oic):
links->status = DL_DEV_UNBINDING
device_links_unbind_consumers(oic):
oic--pinctrl link->status = DL_STATE_SUPPLIER_UNBIND
call device_release_driver_internal(pinctrl)...
device_links_busy(pinctrl):
links->status = DL_DEV_UNBINDING
device_links_unbind_consumers(pinctrl):
pinctrl--i2c link->status = DL_STATE_SUPPLIER_UNBIND
call device_release_driver_internal(i2c)...
device_links_busy(i2c): links->status = DL_DEV_UNBINDING
__device_links_no_driver(i2c)...
pinctrl--i2c link->status is DL_STATE_SUPPLIER_UNBIND
oic--i2c link->status is DL_STATE_ACTIVE
oic--i2c link->supplier->links.status is DL_DEV_UNBINDING
The warning is triggered by the i2c removal because the OIC (supplier)
links status is not DL_DEV_DRIVER_BOUND. Its links status is indeed set
to DL_DEV_UNBINDING.
It is perfectly legit to have the links status set to DL_DEV_UNBINDING
in that case. Indeed we had started to unbind the OIC which triggered
the consumer unbinding and didn't finish yet when the i2c is unbound.
Avoid the warning when the supplier links status is set to
DL_DEV_UNBINDING and thus support this removal sequence without any
warnings. |
| In the Linux kernel, the following vulnerability has been resolved:
tty: serial: 8250: protect against NULL uart->port.dev in register
serial8250_register_8250_port() conditionally copies uart->port.dev
from up->port.dev only when up->port.dev is non-NULL:
if (up->port.dev) {
uart->port.dev = up->port.dev;
...
}
So if both the existing uart slot and up have a NULL ->dev,
uart->port.dev remains NULL. The very next ACPI companion check
then dereferences it unconditionally:
if (!has_acpi_companion(uart->port.dev)) {
has_acpi_companion() reads dev->fwnode without a NULL guard
(include/linux/acpi.h), so this NULL-derefs the kernel for the
remaining no-dev case rather than just skipping the
mctrl_gpio_init() initialisation as intended.
smatch flags the inconsistency:
drivers/tty/serial/8250/8250_core.c:767
serial8250_register_8250_port() error: 'uart->port.dev' could be
null (see line 719)
Guard the call with a NULL check so register continues to work
for callers that legitimately have no parent device (legacy
non-OF/non-ACPI registrations).
No functional change for callers that pass a non-NULL ->dev. |

usb: core: hcd: fix possible deadlock in rh control transfers
>From within the SCSI error handler memory allocations must not
trigger IO. Handling errors in UAS and the storage driver may
involve resetting a device. The thread doing the reset itself
relies on VM magic. However, that is insufficient, as resetting
a device involves resuming it. Resumption as well as resetting
involves conrol transfers to the parent of the device to be reset.
That may be a root hub. Hence usbcore must heed the flags passed
to usb_submit_urb() processing control transfers to root hubs.
The problem exist since the storage driver has been merged. |
| nDPI 5.1.0 contains a memory access issue in the DNS dissector and serializer deserialization code. Specially crafted network input can cause byte-buffer addresses at odd offsets to be cast to uint16_t or wider integer pointers and directly dereferenced without alignment checks. This results in undefined behavior and can cause process termination in UBSan-instrumented builds or on strict-alignment architectures, leading to denial of service. |

in folio_set_bh on the first __bread_gfp call. |
| In the Linux kernel, the following vulnerability has been resolved:
pinctrl: mediatek: paris: bypass pinctrl GPIO layer in set GPIO direction
pinctrl_gpio_direction_input() / pinctrl_gpio_direction_output() take
the pinctrl mutex. This causes a gpiochip operations to need to sleep.
Worse yet, the .can_sleep field in the gpiochip is not set. This causes
the shared GPIO proxy to trip over, as it uses gpiod_cansleep() to check
whether it can use a spinlock or needs a mutex. In this case, it ends
up taking a spinlock, then calls pinctrl_gpio_direction_output(), which
takes a mutex. This causes a huge warning.
While this class of Mediatek hardware does not have separate clear/set
registers, the pinctrl context has a spinlock that is taken whenever
a register read-modify-write is done. Also, once the GPIO function is
selected / muxed in, further GPIO operations do not involve pinctrl
operations or state. The GPIO direction and level values do not require
toggling the pinmux or any other pin config options.
Switch to directly calling mtk_pinmux_gpio_set_direction() in the GPIO
set direction callbacks to avoid taking the pinctrl mutex. Drop the
.gpio_set_direction field in mtk_pmxops to signal we are no longer using
the pinctrl GPIO layer for setting the direction. |
