usb: typec: tcpci: fix of node refcount leak in tcpci_register_port()
I got the following report while doing device(mt6370-tcpc) load
test with CONFIG_OF_UNITTEST and CONFIG_OF_DYNAMIC enabled:
OF: ERROR: memory leak, expected refcount 1 instead of 2,
of_node_get()/of_node_put() unbalanced - destroy cset entry:
attach overlay node /i2c/pmic@34/tcpc/connector
The 'fwnode' set in tcpci_parse_config() which is called
in tcpci_register_port(), its node refcount is increased
in device_get_named_child_node(). It needs be put while
exiting, so call fwnode_handle_put() in the error path of
tcpci_register_port() and in tcpci_unregister_port() to
avoid leak. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: fix double free on tx path.
We see kernel crashes and lockups and KASAN errors related to ax210
firmware crashes. One of the KASAN dumps pointed at the tx path,
and it appears there is indeed a way to double-free an skb.
If iwl_mvm_tx_skb_sta returns non-zero, then the 'skb' sent into the
method will be freed. But, in case where we build TSO skb buffer,
the skb may also be freed in error case. So, return 0 in that particular
error case and do cleanup manually.

| In the Linux kernel, the following vulnerability has been resolved:
memory: of: Fix refcount leak bug in of_get_ddr_timings()
We should add the of_node_put() when breaking out of
for_each_child_of_node() as it will automatically increase
and decrease the refcount. |
| In the Linux kernel, the following vulnerability has been resolved:
regulator: core: fix use_count leakage when handling boot-on
I found a use_count leakage towards supply regulator of rdev with
boot-on option.
┌───────────────────┐ ┌───────────────────┐
│ regulator_dev A │ │ regulator_dev B │
│ (boot-on) │ │ (boot-on) │
│ use_count=0 │◀──supply──│ use_count=1 │
│ │ │ │
└───────────────────┘ └───────────────────┘
In case of rdev(A) configured with `regulator-boot-on', the use_count
of supplying regulator(B) will increment inside
regulator_enable(rdev->supply).
Thus, B will acts like always-on, and further balanced
regulator_enable/disable cannot actually disable it anymore.
However, B was also configured with `regulator-boot-on', we wish it
could be disabled afterwards. |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: vub300: fix return value check of mmc_add_host()
mmc_add_host() may return error, if we ignore its return value, the memory
that allocated in mmc_alloc_host() will be leaked and it will lead a kernel
crash because of deleting not added device in the remove path.
So fix this by checking the return value and goto error path which will call
mmc_free_host(), besides, the timer added before mmc_add_host() needs be del.
And this patch fixes another missing call mmc_free_host() if usb_control_msg()
fails. |

bpf: make sure skb->len != 0 when redirecting to a tunneling device
syzkaller managed to trigger another case where skb->len == 0

entry_SYSCALL_64_after_hwframe+0x61/0xc6
The reproducer doesn't really reproduce outside of syzkaller
environment, so I'm taking a guess here. It looks like we
do generate correct ETH_HLEN-sized packet, but we redirect
the packet to the tunneling device. Before we do so, we
__skb_pull l2 header and arrive again at skb->len == 0.
Doesn't seem like we can do anything better than having
an explicit check after __skb_pull? |
| In the Linux kernel, the following vulnerability has been resolved:
tracing: Fix reading strings from synthetic events
The follow commands caused a crash:
# cd /sys/kernel/tracing
# echo 's:open char file[]' > dynamic_events
# echo 'hist:keys=common_pid:file=filename:onchange($file).trace(open,$file)' > events/syscalls/sys_enter_openat/trigger'
# echo 1 > events/synthetic/open/enable
BOOM!
The problem is that the synthetic event field "char file[]" will read
the value given to it as a string without any memory checks to make sure
the address is valid. The above example will pass in the user space
address and the sythetic event code will happily call strlen() on it
and then strscpy() where either one will cause an oops when accessing
user space addresses.
Use the helper functions from trace_kprobe and trace_eprobe that can
read strings safely (and actually succeed when the address is from user
space and the memory is mapped in).
Now the above can show:

| OpenSynergy BlueSDK (aka Blue SDK) through 6.x mishandles a function call. The specific flaw exists within the BlueSDK Bluetooth stack. The issue results from an incorrect variable used as a function argument. An attacker can leverage this to cause unexpected behavior or obtain sensitive information. |
| OpenSynergy BlueSDK (aka Blue SDK) through 6.x has Incorrect Control Flow Scoping. The specific flaw exists within the BlueSDK Bluetooth stack. The issue results from the lack of proper return control flow after detecting an unusual condition. An attacker can leverage this to bypass a security validation and make the incoming data be processed. |
| OpenSynergy BlueSDK (aka Blue SDK) through 6.x has a Use-After-Free. The specific flaw exists within the BlueSDK Bluetooth stack. The issue results from the lack of validating the existence of an object before performing operations on the object (aka use after free). An attacker can leverage this to achieve remote code execution in the context of a user account under which the Bluetooth process runs. |
| An issue has been discovered in GitLab CE/EE affecting all versions from 10.7 before 18.1.6, 18.2 before 18.2.6, and 18.3 before 18.3.2 that could have allowed authenticated users to disrupt access to token listings and related administrative operations by creating tokens with excessively large names. |
| Certain models of NVR developed by Digiever has an Exposure of Sensitive Information vulnerability, allowing unauthenticated remoter attackers to access the system configuration file and obtain plaintext credentials of the NVR and its connected cameras. |
| Certain models of NVR developed by Digiever has an OS Command Injection vulnerability, allowing authenticated remote attackers to inject arbitrary OS commands and execute them on the device. |
| NUP Pro developed by NewType Infortech has a SQL Injection vulnerability, allowing unauthenticated remote attackers to inject arbitrary SQL commands to read, modify, and delete database contents. |
| NUP Portal developed by NewType Infortech has a Missing Authentication vulnerability, allowing unauthenticated remote attackers to directly upload files. If the attacker manages to bypass the file extension restrictions, they could upload a webshell and execute it on the server side. |
