usb: cdns3: fix random warning message when driver load

🚨 CVE-2022-50206
In the Linux kernel, the following vulnerability has been resolved:
arm64: fix oops in concurrently setting insn_emulation sysctls
emulation_proc_handler() changes table->data for proc_dointvec_minmax
and can generate the following Oops if called concurrently with itself:
| Unable to handle kernel NULL pointer dereference at virtual address 0000000000000010
| Internal error: Oops: 96000006 [#1] SMP

To fix this issue, keep the table->data as &insn->current_mode and
use container_of() to retrieve the insn pointer. Another mutex is
used to protect against the current_mode update but not for retrieving
insn_emulation as table->data is no longer changing.

🚨 CVE-2023-32246
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: call rcu_barrier() in ksmbd_server_exit()
racy issue is triggered the bug by racing between closing a connection
and rmmod. In ksmbd, rcu_barrier() is not called at module unload time,
so nothing prevents ksmbd from getting unloaded while it still has RCU
callbacks pending. It leads to trigger unintended execution of kernel
code locally and use to defeat protections such as Kernel Lockdown

🚨 CVE-2022-50256
In the Linux kernel, the following vulnerability has been resolved:
drm/meson: remove drm bridges at aggregate driver unbind time
drm bridges added by meson_encoder_hdmi_init and meson_encoder_cvbs_init
were not manually removed at module unload time, which caused dangling
references to freed memory to remain linked in the global bridge_list.
When loading the driver modules back in, the same functions would again
call drm_bridge_add, and when traversing the global bridge_list, would
end up peeking into freed memory.

In the Linux kernel, the following vulnerability has been resolved:
drm/meson: remove drm bridges at aggregate driver unbind time
drm bridges added by meson_encoder_hdmi_init and meson_encoder_cvbs_init
were not manually removed at module unload time, which caused dangling
references to freed memory to remain linked in the global bridge_list.
When loading the driver modules back in, the same functions would again
call drm_bridge_add, and when traversing the global bridge_list, would
end up peeking into freed memory.
Once again KASAN revealed the problem:

🚨 CVE-2022-50273
In the Linux kernel, the following vulnerability has been resolved:

If we enable CONFIG_F2FS_CHECK_FS config, it will trigger a kernel panic
instead of warning.
The root cause is: in fuzzed image, SIT table is inconsistent with inode
mapping table, result in triggering such warning during SIT table update.
This patch introduces a new flag DATA_GENERIC_ENHANCE_UPDATE, w/ this
flag, data block recovery flow can check destination blkaddr's validation
in SIT table, and skip f2fs_replace_block() to avoid inconsistent status.

🚨 CVE-2022-50303
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix double release compute pasid
If kfd_process_device_init_vm returns failure after vm is converted to
compute vm and vm->pasid set to compute pasid, KFD will not take
pdd->drm_file reference. As a result, drm close file handler maybe
called to release the compute pasid before KFD process destroy worker to
release the same pasid and set vm->pasid to zero, this generates below
WARNING backtrace and NULL pointer access.
Add helper amdgpu_amdkfd_gpuvm_set_vm_pasid and call it at the last step
of kfd_process_device_init_vm, to ensure vm pasid is the original pasid
if acquiring vm failed or is the compute pasid with pdd->drm_file
reference taken to avoid double release same pasid.

🚨 CVE-2022-50336
In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Add null pointer check to attr_load_runs_vcn
Some metadata files are handled before MFT. This adds a null pointer
check for some corner cases that could lead to NPD while reading these
metadata files for a malformed NTFS image.

🚨 CVE-2022-50407
In the Linux kernel, the following vulnerability has been resolved:
crypto: hisilicon/qm - increase the memory of local variables
Increase the buffer to prevent stack overflow by fuzz test. The maximum
length of the qos configuration buffer is 256 bytes. Currently, the value
of the 'val buffer' is only 32 bytes. The sscanf does not check the dest
memory length. So the 'val buffer' may stack overflow.

🚨 CVE-2022-50418
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: mhi: fix potential memory leak in ath11k_mhi_register()
mhi_alloc_controller() allocates a memory space for mhi_ctrl. When gets
some error, mhi_ctrl should be freed with mhi_free_controller(). But
when ath11k_mhi_read_addr_from_dt() fails, the function returns without
calling mhi_free_controller(), which will lead to a memory leak.
We can fix it by calling mhi_free_controller() when
ath11k_mhi_read_addr_from_dt() fails.

In the Linux kernel, the following vulnerability has been resolved:
crypto: hisilicon/hpre - fix resource leak in remove process
In hpre_remove(), when the disable operation of qm sriov failed,
the following logic should continue to be executed to release the
remaining resources that have been allocated, instead of returning
directly, otherwise there will be resource leakage.

🚨 CVE-2022-50442
In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Validate buffer length while parsing index
indx_read is called when we have some NTFS directory operations that
need more information from the index buffers. This adds a sanity check
to make sure the returned index buffer length is legit, or we may have
some out-of-bound memory accesses.

In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Validate buffer length while parsing index
indx_read is called when we have some NTFS directory operations that
need more information from the index buffers. This adds a sanity check
to make sure the returned index buffer length is legit, or we may have
some out-of-bound memory accesses.
