media: cx25821: Fix the warning when removing the module
When removing the module, we will get the following warning:

media: pci: cx23885: Fix the error handling in cx23885_initdev()
When the driver fails to call the dma_set_mask(), the driver will get
the following splat:
[ 55.853884] BUG: KASAN: use-after-free in __process_removed_driver+0x3c/0x240

This is because the driver has initialized the i2c related resources
in cx23885_dev_setup() but not released them in error handling, fix this
bug by modifying the error path that jumps after failing to call the
dma_set_mask(). |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: jz4740: Apply DMA engine limits to maximum segment size
Do what is done in other DMA-enabled MMC host drivers (cf. host/mmci.c) and
limit the maximum segment size based on the DMA engine's capabilities. This
is needed to avoid warnings like the following with CONFIG_DMA_API_DEBUG=y.

| In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix resource leak in lpfc_sli4_send_seq_to_ulp()
If no handler is found in lpfc_complete_unsol_iocb() to match the rctl of a
received frame, the frame is dropped and resources are leaked.
Fix by returning resources when discarding an unhandled frame type. Update
lpfc_fc_frame_check() handling of NOP basic link service. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Inhibit aborts if external loopback plug is inserted
After running a short external loopback test, when the external loopback is
removed and a normal cable inserted that is directly connected to a target
device, the system oops in the llpfc_set_rrq_active() routine.
When the loopback was inserted an FLOGI was transmit. As we're looped back,
we receive the FLOGI request. The FLOGI is ABTS'd as we recognize the same
wppn thus understand it's a loopback. However, as the ABTS sends address
information the port is not set to (fffffe), the ABTS is dropped on the
wire. A short 1 frame loopback test is run and completes before the ABTS
times out. The looback is unplugged and the new cable plugged in, and the
an FLOGI to the new device occurs and completes. Due to a mixup in ref
counting the completion of the new FLOGI releases the fabric ndlp. Then the
original ABTS completes and references the released ndlp generating the
oops.
Correct by no-op'ing the ABTS when in loopback mode (it will be dropped
anyway). Added a flag to track the mode to recognize when it should be
no-op'd. |
| In the Linux kernel, the following vulnerability has been resolved:
net: remove two BUG() from skb_checksum_help()
I have a syzbot report that managed to get a crash in skb_checksum_help()
If syzbot can trigger these BUG(), it makes sense to replace
them with more friendly WARN_ON_ONCE() since skb_checksum_help()
can instead return an error code.
Note that syzbot will still crash there, until real bug is fixed. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: fix a NULL pointer dereference in nvme_alloc_admin_tags
In nvme_alloc_admin_tags, the admin_q can be set to an error (typically
-ENOMEM) if the blk_mq_init_queue call fails to set up the queue, which
is checked immediately after the call. However, when we return the error
message up the stack, to nvme_reset_work the error takes us to
nvme_remove_dead_ctrl()
nvme_dev_disable()
nvme_suspend_queue(&dev->queues[0]).
Here, we only check that the admin_q is non-NULL, rather than not
an error or NULL, and begin quiescing a queue that never existed, leading
to bad / NULL pointer dereference. |
| In the Linux kernel, the following vulnerability has been resolved:
net: phy: micrel: Allow probing without .driver_data
Currently, if the .probe element is present in the phy_driver structure
and the .driver_data is not, a NULL pointer dereference happens.
Allow passing .probe without .driver_data by inserting NULL checks
for priv->type. |
| In the Linux kernel, the following vulnerability has been resolved:
ARM: versatile: Add missing of_node_put in dcscb_init
The device_node pointer is returned by of_find_compatible_node
with refcount incremented. We should use of_node_put() to avoid
the refcount leak. |
| In the Linux kernel, the following vulnerability has been resolved:
ARM: hisi: Add missing of_node_put after of_find_compatible_node
of_find_compatible_node will increment the refcount of the returned
device_node. Calling of_node_put() to avoid the refcount leak |
| In the Linux kernel, the following vulnerability has been resolved:
powerpc/rtas: Keep MSR[RI] set when calling RTAS
RTAS runs in real mode (MSR[DR] and MSR[IR] unset) and in 32-bit big
endian mode (MSR[SF,LE] unset).
The change in MSR is done in enter_rtas() in a relatively complex way,
since the MSR value could be hardcoded.
Furthermore, a panic has been reported when hitting the watchdog interrupt
while running in RTAS, this leads to the following stack trace:

This happens because MSR[RI] is unset when entering RTAS but there is no
valid reason to not set it here.
RTAS is expected to be called with MSR[RI] as specified in PAPR+ section
"7.2.1 Machine State":
R1–7.2.1–9. If called with MSR[RI] equal to 1, then RTAS must protect
its own critical regions from recursion by setting the MSR[RI] bit to
0 when in the critical regions.
Fixing this by reviewing the way MSR is compute before calling RTAS. Now a
hardcoded value meaning real

Input: gpio-keys - cancel delayed work only in case of GPIO
gpio_keys module can either accept gpios or interrupts. The module
initializes delayed work in case of gpios only and is only used if
debounce timer is not used, so make sure cancel_delayed_work_sync()
is called only when its gpio-backed and debounce_use_hrtimer is false.
This fixes the issue seen below when the gpio_keys module is unloaded and
an interrupt pin is used instead of GPIO:

The root cause of this issue is we destory inline data until call
ext4_writepages under delay allocation mode. But there maybe already
convert from inline to extent. To solve this issue, we call
filemap_flush first.. |
| In the Linux kernel, the following vulnerability has been resolved:
mips: cpc: Fix refcount leak in mips_cpc_default_phys_base
Add the missing of_node_put() to release the refcount incremented
by of_find_compatible_node(). |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/arm-smmu-v3: check return value after calling platform_get_resource()
It will cause null-ptr-deref if platform_get_resource() returns NULL,
we need check the return value. |
| In the Linux kernel, the following vulnerability has been resolved:
drivers: staging: rtl8192e: Fix deadlock in rtllib_beacons_stop()
There is a deadlock in rtllib_beacons_stop(), which is shown
below:
(Thread 1) | (Thread 2)
| rtllib_send_beacon()
rtllib_beacons_stop() | mod_timer()
spin_lock_irqsave() //(1) | (wait a time)
... | rtllib_send_beacon_cb()
del_timer_sync() | spin_lock_irqsave() //(2)
(wait timer to stop) | ...
We hold ieee->beacon_lock in position (1) of thread 1 and
use del_timer_sync() to wait timer to stop, but timer handler
also need ieee->beacon_lock in position (2) of thread 2.
As a result, rtllib_beacons_stop() will block forever.
This patch extracts del_timer_sync() from the protection of
spin_lock_irqsave(), which could let timer handler to obtain
the needed lock. |
| In the Linux kernel, the following vulnerability has been resolved:
tty: Fix a possible resource leak in icom_probe
When pci_read_config_dword failed, call pci_release_regions() and
pci_disable_device() to recycle the resource previously allocated. |
