6.16-stable review patch. If anyone has any objections, please let me know.

------------------

From: Yu Kuai <[email protected]>

commit ba28afbd9eff2a6370f23ef4e6a036ab0cfda409 upstream.

In the case user trigger tags grow by queue sysfs attribute nr_requests, hctx->sched_tags will be freed directly and replaced with a new allocated tags, see blk_mq_tag_update_depth().

The problem is that hctx->sched_tags is from elevator->et->tags, while et->tags is still the freed tags, hence later elevator exit will try to free the tags again, causing kernel panic.

Fix this problem by replacing et->tags with new allocated tags as well.

Noted there are still some long term problems that will require some refactor to be fixed thoroughly[1].

commit 27e06650a5eafe832a90fd2604f0c5e920857fae upstream.

A buffer overflow arises from the usage of snprintf to write into the buffer "buf" in target_lu_gp_members_show function located in /drivers/target/target_core_configfs.c. This buffer is allocated with size LU_GROUP_NAME_BUF (256 bytes).

snprintf(...) formats multiple strings into buf with the HBA name (hba->hba_group.cg_item), a slash character, a devicename (dev-> dev_group.cg_item) and a newline character, the total formatted string length may exceed the buffer size of 256 bytes.

Since snprintf() returns the total number of bytes that would have been written (the length of %s/%sn ), this value may exceed the buffer length (256 bytes) passed to memcpy(), this will ultimately cause function memcpy reporting a buffer overflow error.

An additional check of the return value of snprintf() can avoid this buffer overflow.

commit 9f2c0ac1423d5f267e7f1d1940780fc764b0fee3 upstream.

The previous commit 0718a78f6a9f ("ALSA: usb-audio: Kill timer properly at removal") patched a UAF issue caused by the error timer.

However, because the error timer kill added in this patch occurs after the endpoint delete, a race condition to UAF still occurs, albeit rarely.

Additionally, since kill-cleanup for urb is also missing, freed memory can be accessed in interrupt context related to urb, which can cause UAF.

Therefore, to prevent this, error timer and urb must be killed before freeing the heap memory.

From: Duoming Zhou <[email protected]>

commit 01e03fb7db419d39e18d6090d4873c1bff103914 upstream.

The original code uses cancel_delayed_work() in flexcop_pci_remove(), which does not guarantee that the delayed work item irq_check_work has fully completed if it was already running. This leads to use-after-free scenarios where flexcop_pci_remove() may free the flexcop_device while irq_check_work is still active and attempts to dereference the device.

A typical race condition is illustrated below:

CPU 0 (remove)                         | CPU 1 (delayed work callback)
flexcop_pci_remove()                   | flexcop_pci_irq_check_work()
  cancel_delayed_work()                |
  flexcop_device_kfree(fc_pci->fc_dev) |
                                       |   fc = fc_pci->fc_dev; // UAF

This is confirmed by a KASAN report:

Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensure that the delayed work item is properly canceled and any executing delayed work has finished before the device memory is deallocated.

This bug was initially identified through static analysis. To reproduce and test it, I simulated the B2C2 FlexCop PCI device in QEMU and introduced artificial delays within the flexcop_pci_irq_check_work() function to increase the likelihood of triggering the bug.

commit 79d10f4f21a92e459b2276a77be62c59c1502c9d upstream.

The state->timer is a cyclic timer that schedules work_i2c_poll and delayed_work_enable_hotplug, while rearming itself. Using timer_delete() fails to guarantee the timer isn't still running when destroyed, similarly cancel_delayed_work() cannot ensure delayed_work_enable_hotplug has terminated if already executing. During probe failure after timer initialization, these may continue running as orphans and reference the already-freed tc358743_state object through tc358743_irq_poll_timer.

The following is the trace captured by KASAN.

Replace timer_delete() with timer_delete_sync() and cancel_delayed_work() with cancel_delayed_work_sync() to ensure proper termination of timer and work items before resource cleanup.

This bug was initially identified through static analysis. For reproduction and testing, I created a functional emulation of the tc358743 device via a kernel module and introduced faults through the debugfs interface.

commit 40b7a19f321e65789612ebaca966472055dab48c upstream.

The original code uses cancel_delayed_work() in xc5000_release(), which does not guarantee that the delayed work item timer_sleep has fully completed if it was already running. This leads to use-after-free scenarios where xc5000_release() may free the xc5000_priv while timer_sleep is still active and attempts to dereference the xc5000_priv.

A typical race condition is illustrated below:

CPU 0 (release thread)                 | CPU 1 (delayed work callback)
xc5000_release()                       | xc5000_do_timer_sleep()
  cancel_delayed_work()                |
  hybrid_tuner_release_state(priv)     |
    kfree(priv)                        |
                                       |   priv = container_of() // UAF

Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensure that the timer_sleep is properly canceled before the xc5000_priv memory is deallocated.

A deadlock concern was considered: xc5000_release() is called in a process context and is not holding any locks that the timer_sleep work item might also need. Therefore, the use of the _sync() variant is safe here.

This bug was initially identified through static analysis.

The iMON driver improperly releases the usb_device reference in imon_disconnect without coordinating with active users of the device.

Specifically, the fields usbdev_intf0 and usbdev_intf1 are not protected by the users counter (ictx->users). During probe, imon_init_intf0 or imon_init_intf1 increments the usb_device reference count depending on the interface. However, during disconnect, usb_put_dev is called unconditionally, regardless of actual usage.

As a result, if vfd_write or other operations are still in progress after disconnect, this can lead to a use-after-free of the usb_device pointer.

                                          usb_put_dev(ictx->usbdev_intf0)
                                        else

        ictx->usbdev_intf0) UAF
    else
      pipe = usb_sndctrlpipe(
        ictx->usbdev_intf0, 0) UAF

Guard access to usbdev_intf0 and usbdev_intf1 after disconnect by checking ictx->disconnected in all writer paths. Add early return with -ENODEV in send_packet(), vfd_write(), lcd_write() and display_open() if the device is no longer present.

Set and read ictx->disconnected under ictx->lock to ensure memory synchronization. Acquire the lock in imon_disconnect() before setting the flag to synchronize with any ongoing operations.

Ensure writers exit early and safely after disconnect before the USB core proceeds with cleanup.

From: Thadeu Lima de Souza Cascardo <[email protected]>

commit 0e2ee70291e64a30fe36960c85294726d34a103e upstream.

Per UVC 1.1+ specification 3.7.2, units and terminals must have a non-zero unique ID.

```
Each Unit and Terminal within the video function is assigned a unique
identification number, the Unit ID (UID) or Terminal ID (TID), contained in
the bUnitID or bTerminalID field of the descriptor. The value 0x00 is
reserved for undefined ID,
```

If we add a new entity with id 0 or a duplicated ID, it will be marked as UVC_INVALID_ENTITY_ID.

In a previous attempt commit 3dd075fe8ebb ("media: uvcvideo: Require entities to have a non-zero unique ID"), we ignored all the invalid units, this broke a lot of non-compatible cameras. Hopefully we are more lucky this time.

This also prevents some syzkaller reproducers from triggering warnings due to a chain of entities referring to themselves. In one particular case, an Output Unit is connected to an Input Unit, both with the same ID of 1. But when looking up for the source ID of the Output Unit, that same entity is found instead of the input entity, which leads to such warnings.

In another case, a backward chain was considered finished as the source ID was 0. Later on, that entity was found, but its pads were not valid.

Here is a sample stack trace for one of those cases.

commit 1367da7eb875d01102d2ed18654b24d261ff5393 upstream.

It is possible to hit a zero entry while traversing the vmas in unuse_mm() called from swapoff path and accessing it causes the OOPS:

Unable to handle kernel NULL pointer dereference at virtual address

The issue is manifested from the below race between the fork() on a process and swapoff:

copy_nonpresent_pte():
The dst mm is added into the
mmlist to be visible to the
swapoff operation.

3) Fatal signal is sent to the parent
process(which is the current during the
fork) thus skip the duplication of the
vmas and mark the vma range with
XA_ZERO_ENTRY as a marker for this process
that helps during exit_mmap().

4) swapoff is tried on the 'mm' added to the 'mmlist' as part of the 2.

5) unuse_mm(), that iterates through the vma's of this 'mm' will hit the non-NULL zero entry and operating on this zero entry as a vma is resulting into the oops.

The proper fix would be around not exposing this partially-valid tree to others when droping the mmap lock, which is being solved with [1]. A simpler solution would be checking for MMF_UNSTABLE, as it is set if mm_struct is not fully initialized in dup_mmap().

Thanks to Liam/Lorenzo/David for all the suggestions in fixing this issue.

commit 3fd2ef2ae2b5c955584a3bee8e83ae7d7a98f782 upstream.

If ab->fw.m3_data points to data, then fw pointer remains null. Further, if m3_mem is not allocated, then fw is dereferenced to be passed to ath11k_err function.

Replace fw->size by m3_len.

commit 02a24f13b3a1d9da9f3de56aa5fdb7cc1fe167a2 upstream.

One internal buffer which is allocated only once per session was not being freed during session close because it was not being tracked as part of internal buffer list which resulted in a memory leak.

Add the necessary logic to explicitly free the untracked internal buffer during session close to ensure all allocated memory is released properly.

commit 80eaf32672871bd2623ce6ba13ffc1f018756580 upstream.

In 'stm32_csi_start', 'csidev->s_subdev' is dereferenced directly while assigning a value to the 'src_pad'. However the same value is being checked against NULL at a later point of time indicating that there are chances that the value can be NULL.

Move the dereference after the NULL check.

It is possible that the topology parsing function audioreach_widget_load_module_common() could return NULL or an error pointer. Add missing NULL check so that we do not dereference it.
