| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: pci: configure manual DAC mode via PCI config API only
To support 36-bit DMA, configure chip proprietary bit via PCI config API
or chip DBI interface. However, the PCI device mmap isn't set yet and
the DBI is also inaccessible via mmap, so only if the bit can be accessible
via PCI config API, chip can support 36-bit DMA. Otherwise, fallback to
32-bit DMA.
With NULL mmap address, kernel throws trace:

| The Four-Faith F3x36 router using firmware v2.0.0 is vulnerable to an
authentication bypass vulnerability in the administrative web server. Authentication is not enforced on some administrative functionality when using the "bapply.cgi" endpoint instead of the normal "apply.cgi" endpoint. A remote and unauthenticated can use this vulnerability to modify settings or chain with existing authenticated vulnerabilities. |
| A weakness has been identified in D-Link DI-7001 MINI 24.04.18B1. Impacted is an unknown function of the file /upgrade_filter.asp. This manipulation of the argument path causes os command injection. The attack may be initiated remotely. The exploit has been made available to the public and could be exploited. |
| BigAntSoft BigAnt Server, up to and including version 5.6.06, is vulnerable to unauthenticated remote code execution via account registration. An unauthenticated remote attacker can create an administrative user through the default exposed SaaS registration mechanism. Once an administrator, the attacker can upload and execute arbitrary PHP code using the "Cloud Storage Addin," leading to unauthenticated code execution. |
| A security vulnerability has been detected in D-Link DI-7001 MINI 24.04.18B1. The affected element is an unknown function of the file /dbsrv.asp. Such manipulation of the argument str leads to buffer overflow. The attack may be launched remotely. The exploit has been disclosed publicly and may be used. |
| Insufficient input sanitization in the dashboard label or path can allow
an attacker to trigger a device error causing information disclosure or
data manipulation. |
| In the Linux kernel, the following vulnerability has been resolved:
misc: tps6594-pfsm: Add NULL pointer check in tps6594_pfsm_probe()
The returned value, pfsm->miscdev.name, from devm_kasprintf()
could be NULL.
A pointer check is added to prevent potential NULL pointer dereference.
This is similar to the fix in commit 3027e7b15b02
("ice: Fix some null pointer dereference issues in ice_ptp.c").
This issue is found by our static analysis tool. |
| Due to insufficient sanitization, an attacker can upload a specially
crafted configuration file to traverse directories and achieve remote
code execution with system-level permissions. |
| In the Linux kernel, the following vulnerability has been resolved:
block: don't use submit_bio_noacct_nocheck in blk_zone_wplug_bio_work
Bios queued up in the zone write plug have already gone through all all
preparation in the submit_bio path, including the freeze protection.
Submitting them through submit_bio_noacct_nocheck duplicates the work
and can can cause deadlocks when freezing a queue with pending bio
write plugs.
Go straight to ->submit_bio or blk_mq_submit_bio to bypass the
superfluous extra freeze protection and checks. |
| In the Linux kernel, the following vulnerability has been resolved:
nvmem: zynqmp_nvmem: unbreak driver after cleanup
Commit 29be47fcd6a0 ("nvmem: zynqmp_nvmem: zynqmp_nvmem_probe cleanup")
changed the driver to expect the device pointer to be passed as the
"context", but in nvmem the context parameter comes from nvmem_config.priv
which is never set - Leading to null pointer exceptions when the device is
accessed. |
| In the Linux kernel, the following vulnerability has been resolved:
PM: EM: Fix potential division-by-zero error in em_compute_costs()
When the device is of a non-CPU type, table[i].performance won't be
initialized in the previous em_init_performance(), resulting in division
by zero when calculating costs in em_compute_costs().
Since the 'cost' algorithm is only used for EAS energy efficiency
calculations and is currently not utilized by other device drivers, we
should add the _is_cpu_device(dev) check to prevent this division-by-zero
issue. |

by requesting a contiguous physical memory for the DMA mapping. |

firmware: arm_ffa: Fix memory leak by freeing notifier callback node
Commit e0573444edbf ("firmware: arm_ffa: Add interfaces to request
notification callbacks") adds support for notifier callbacks by allocating
and inserting a callback node into a hashtable during registration of
notifiers. However, during unregistration, the code only removes the
node from the hashtable without freeing the associated memory, resulting
in a memory leak.
Resolve the memory leak issue by ensuring the allocated notifier callback
node is properly freed after it is removed from the hashtable entry. |

firmware: arm_ffa: Replace mutex with rwlock to avoid sleep in atomic context
The current use of a mutex to protect the notifier hashtable accesses
can lead to issues in the atomic context. It results in the below
kernel warnings:

To address this, replace the mutex with an rwlock to protect the notifier
hashtable accesses. This ensures that read-side locking does not sleep and
multiple readers can acquire the lock concurrently, avoiding unnecessary
contention and potential deadlocks. Writer access remains exclusive,
preserving correctness.
This change resolves warnings from lockdep about potential sleep in
atomic context. |

allocating the heap in proc_vmalloc_init() and passing the heap address to
m->private, vmalloc_info_show() should allocate the heap. |

HID: appletb-kbd: fix slab use-after-free bug in appletb_kbd_probe
In probe appletb_kbd_probe() a "struct appletb_kbd *kbd" is allocated
via devm_kzalloc() to store touch bar keyboard related data.
Later on if backlight_device_get_by_name() finds a backlight device
with name "appletb_backlight" a timer (kbd->inactivity_timer) is setup
with appletb_inactivity_timer() and the timer is armed to run after
appletb_tb_dim_timeout (60) seconds.
A use-after-free is triggered when failure occurs after the timer is
armed. This ultimately means probe failure occurs and as a result the
"struct appletb_kbd *kbd" which is device managed memory is freed.
After 60 seconds the timer will have expired and __run_timers will
attempt to access the timer (kbd->inactivity_timer) however the kdb
structure has been freed causing a use-after free.

The root cause of the issue is that the timer is not disarmed
on failure paths leading to it remaining active and accessing
freed memory. To fix this call timer_delete_sync() to deactivate
the timer.
Another small issue is that timer_delete_sync is called
unconditionally in appletb_kbd_remove(), fix this by checking
for a valid kbd->backlight_dev before calling timer_delete_sync. |

usb: chipidea: udc: disconnect/reconnect from host when do suspend/resume
Shawn and John reported a hang issue during system suspend as below:
- USB gadget is enabled as Ethernet
- There is data transfer over USB Ethernet (scp a big file between host
and device)
- Device is going in/out suspend (echo mem > /sys/power/state)
The root cause is the USB device controller is suspended but the USB bus
is still active which caused the USB host continues to transfer data with
device and the device continues to queue USB requests (in this case, a
delayed TCP ACK packet trigger the issue) after controller is suspended,
however the USB controller clock is already gated off. Then if udc driver
access registers after that point, the system will hang.
The correct way to avoid such issue is to disconnect device from host when
the USB bus is not at suspend state. Then the host will receive disconnect
event and stop data transfer in time. To continue make USB gadget device
work after system resume, this will reconnect device automatically.
To make usb wakeup work if USB bus is already at suspend state, this will
keep connection for it only when USB device controller has enabled wakeup
capability. |
