| In the Linux kernel, the following vulnerability has been resolved:
arm64: dts: qcom: x1e80100: Add GPU cooling
Unlike the CPU, the GPU does not throttle its speed automatically when it
reaches high temperatures. With certain high GPU loads it is possible to
reach the critical hardware shutdown temperature of 120°C, endangering the
hardware and making it impossible to run certain applications.
Set up GPU cooling similar to the ACPI tables, by throttling the GPU speed
when reaching 95°C and polling every 200ms. |
| Project Pier 0.8.8 and earlier contains an unauthenticated arbitrary file upload vulnerability in tools/upload_file.php. The upload handler fails to validate the file type or enforce authentication, allowing remote attackers to upload malicious PHP files directly into a web-accessible directory. The uploaded file is stored with a predictable suffix and can be executed by requesting its URL, resulting in remote code execution. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: don't warn when if there is a FW error
iwl_trans_reclaim is warning if it is called when the FW is not alive.
But if it is called when there is a pending restart, i.e. after a FW
error, there is no need to warn, instead - return silently. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Don't treat wb connector as physical in create_validate_stream_for_sink
Don't try to operate on a drm_wb_connector as an amdgpu_dm_connector.
While dereferencing aconnector->base will "work" it's wrong and
might lead to unknown bad things. Just... don't. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Disable SCO support if READ_VOICE_SETTING is unsupported/broken
A SCO connection without the proper voice_setting can cause
the controller to lock up. |
| ClanSphere 2011.3 is vulnerable to a local file inclusion (LFI) flaw due to improper handling of the cs_lang cookie parameter. The application fails to sanitize user-supplied input, allowing attackers to traverse directories and read arbitrary files outside the web root. The vulnerability is further exacerbated by null byte injection (%00) to bypass file extension checks. |
| A vulnerability was determined in SourceCodester Student Grades Management System 1.0. Affected is the function create_classroom of the file /classroom.php of the component My Classrooms Management Page. This manipulation of the argument name/description causes stored cross site scripting. |
| Nagios Log Server versions prior to 2026R1.0.1 contain an authenticated command injection vulnerability via the experimental 'Natural Language Queries' feature. Configuration values for this feature are read from the application settings and incorporated into a system command without adequate validation or restriction of special characters. An authenticated user with access to global configuration can abuse these settings to execute arbitrary operating system commands with the privileges of the web server account, leading to compromise of the Log Server host. |
| Nagios Log Server versions prior to 2026R1.0.1 are vulnerable to local privilege escalation due to unsafe interaction between sudo rules and file system permissions. The web server account is granted passwordless sudo access to certain maintenance scripts while also being a member of a group that has write access to the directory containing those scripts. A local attacker running as the web server user can replace one of the permitted scripts with a malicious program and then execute it via sudo, resulting in arbitrary code execution with root privileges. |
| In the Linux kernel, the following vulnerability has been resolved:
intel_th: Fix a resource leak in an error handling path
If an error occurs after calling 'pci_alloc_irq_vectors()',
'pci_free_irq_vectors()' must be called as already done in the remove
function. |
| In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Fix buffer locking in ring_buffer_subbuf_order_set()
Enlarge the critical section in ring_buffer_subbuf_order_set() to
ensure that error handling takes place with per-buffer mutex held,
thus preventing list corruption and other concurrency-related issues. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Kill timer properly at removal
The USB-audio MIDI code initializes the timer, but in a rare case, the
driver might be freed without the disconnect call. This leaves the
timer in an active state while the assigned object is released via
snd_usbmidi_free(), which ends up with a kernel warning when the debug
configuration is enabled, as spotted by fuzzer.
For avoiding the problem, put timer_shutdown_sync() at
snd_usbmidi_free(), so that the timer can be killed properly.
While we're at it, replace the existing timer_delete_sync() at the
disconnect callback with timer_shutdown_sync(), too. |
| In the Linux kernel, the following vulnerability has been resolved:
soundwire: revisit driver bind/unbind and callbacks
In the SoundWire probe, we store a pointer from the driver ops into
the 'slave' structure. This can lead to kernel oopses when unbinding
codec drivers, e.g. with the following sequence to remove machine
driver and codec driver.
/sbin/modprobe -r snd_soc_sof_sdw
/sbin/modprobe -r snd_soc_rt711
The full details can be found in the BugLink below, for reference the
two following examples show different cases of driver ops/callbacks
being invoked after the driver .remove().

This was not detected earlier in Intel tests since the tests first
remove the parent PCI device and shut down the bus. The sequence
above is a corner case which keeps the bus operational but without a
driver bound.
While trying to solve this kernel oopses, it became clear that the
existing SoundWire bus does not deal well with the unbind case.
Commit 528be501b7d4a ("soundwire: sdw_slave: add probe_complete structure and new fields")
added a 'probed' status variable and a 'probe_complete'
struct completion. This status is however not reset on remove and
likewise the 'probe complete' is not re-initialized, so the
bind/unbind/bind test cases would fail. The timeout used before the
'update_status' callback was also a bad idea in hindsight, there
should really be no timing assumption as to if and when a driver is
bound to a device.
An initial draft was based on device_lock() and device_unlock() was
tested. This proved too complicated, with deadlocks created during the
suspend-resume sequences, which also use the same device_lock/unlock()
as the bind/unbind sequences. On a CometLake device, a bad DSDT/BIOS
caused spurious resumes and the use of device_lock() caused hangs
during suspend. After multiple weeks or testing and painful
reverse-engineering of deadlocks on different devices, we looked for
alternatives that did not interfere with the device core.
A bus notifier was used successfully to keep track of DRIVER_BOUND and
DRIVER_UNBIND events. This solved the bind-unbind-bind case in tests,
but it can still be defeated with a theoretical corner case where the
memory is freed by a .remove while the callback is in use. The
notifier only helps make sure the driver callbacks are valid, but not
that the memory allocated in probe remains valid while the callbacks
are invoked.
This patch suggests the introduction of a new 'sdw_dev_lock' mutex
protecting probe/remove and all driver callbacks. Since this mutex is
'local' to SoundWire only, it does not interfere with existing locks
and does not create deadlocks. In addition, this patch removes the
'probe_complete' completion, instead we directly invoke the
'update_status' from the probe routine. That removes any sort of
timing dependency and a much better support for the device/driver
model, the driver could be bound before the bus started, or eons after
the bus started and the hardware would be properly initialized in all
cases.

This happens because of data race. Each thread rewrite channels's
descriptor as soon as device_prep_dma_memcpy() is called. It leads to the
situation when the driver thinks that it uses right descriptor that
actually is freed or substituted for other one.
With current fixes a descriptor changes its value only when it has
been used. A new descriptor is acquired from vc->desc_issued queue that
is already filled with descriptors that are ready to be sent. Threads
have no direct access to DMA channel descriptor. Now it is just possible
to queue a descriptor for further processing. |

net/mdiobus: Fix potential out-of-bounds clause 45 read/write access
When using publicly available tools like 'mdio-tools' to read/write data
from/to network interface and its PHY via C45 (clause 45) mdiobus,
there is no verification of parameters passed to the ioctl and
it accepts any mdio address.
Currently there is support for 32 addresses in kernel via PHY_MAX_ADDR define,
but it is possible to pass higher value than that via ioctl.
While read/write operation should generally fail in this case,
mdiobus provides stats array, where wrong address may allow out-of-bounds
read/write.
Fix that by adding address verification before C45 read/write operation.
While this excludes this access from any statistics, it improves security of
read/write operation. |

| A vulnerability was found in Podman, Buildah, and CRI-O. A symlink traversal vulnerability in the containers/storage library can cause Podman, Buildah, and CRI-O to hang and result in a denial of service via OOM kill when running a malicious image using an automatically assigned user namespace (`--userns=auto` in Podman and Buildah). The containers/storage library will read /etc/passwd inside the container, but does not properly validate if that file is a symlink, which can be used to cause the library to read an arbitrary file on the host. |
| In the Linux kernel, the following vulnerability has been resolved:
e1000: Move cancel_work_sync to avoid deadlock
Previously, e1000_down called cancel_work_sync for the e1000 reset task
(via e1000_down_and_stop), which takes RTNL.
As reported by users and syzbot, a deadlock is possible in the following
scenario:
CPU 0:
- RTNL is held
- e1000_close
- e1000_down
- cancel_work_sync (cancel / wait for e1000_reset_task())
CPU 1:
- process_one_work
- e1000_reset_task
- take RTNL
To remedy this, avoid calling cancel_work_sync from e1000_down
(e1000_reset_task does nothing if the device is down anyway). Instead,
call cancel_work_sync for e1000_reset_task when the device is being
removed. |
