Cognex In-Sight Explorer and In-Sight Camera Firmware expose
a proprietary protocol on TCP port 1069 to perform management operations
such as modifying system properties. The user management functionality
handles sensitive data such as registered usernames and passwords over
an unencrypted channel, allowing an adjacent attacker to intercept valid
credentials to gain access to the device. |
Dover Fueling Solutions ProGauge MagLink LX4 Devices fail to handle Unix time values beyond a certain point.
An attacker can manually change the system time to exploit this
limitation, potentially causing errors in authentication and leading to a
denial-of-service condition. |

Let's initialize the MR recovery work before MR allocate to prevent
the warning, remove the MRs from the list to prevent the UAF. |
An attacker with adjacent access, without authentication, can exploit
this vulnerability to retrieve a hard-coded password embedded in
publicly available software. This password can then be used to decrypt
sensitive network traffic, affecting the Cognex device. |
Cognex In-Sight Explorer and In-Sight Camera Firmware expose a telnet-based service on port 23 in order to allow
management operations on the device such as firmware upgrades and device
reboot requiring an authentication. A wrong management of login
failures of the service allows a denial-of-service attack, leaving the telnet service
into an unreachable state. |

In the Linux kernel, the following vulnerability has been resolved:
HID: intel-ish-hid: Fix kernel panic during warm reset
During warm reset device->fw_client is set to NULL. If a bus driver is
registered after this NULL setting and before new firmware clients are
enumerated by ISHTP, kernel panic will result in the function
ishtp_cl_bus_match(). This is because of reference to
device->fw_client->props.protocol_name.
ISH firmware after getting successfully loaded, sends a warm reset
notification to remove all clients from the bus and sets
device->fw_client to NULL. Until kernel v5.15, all enabled ISHTP kernel
module drivers were loaded right after any of the first ISHTP device was
registered, regardless of whether it was a matched or an unmatched
device. This resulted in all drivers getting registered much before the
warm reset notification from ISH.
Starting kernel v5.16, this issue got exposed after the change was
introduced to load only bus drivers for the respective matching devices.
In this scenario, cros_ec_ishtp device and cros_ec_ishtp driver are
registered after the warm reset device fw_client NULL setting.
cros_ec_ishtp driver_register() triggers the callback to
ishtp_cl_bus_match() to match ISHTP driver to the device and causes kernel
panic in guid_equal() when dereferencing fw_client NULL pointer to get
protocol_name. |

During the CLC handshake, server sequentially tries available SMCRv2
and SMCRv1 devices in smc_listen_work().
If an SMCRv2 device is found. SMCv2 based link group and link will be
assigned to the connection. Then assumed that some buffer assignment
errors happen later in the CLC handshake, such as RMB registration
failure, server will give up SMCRv2 and try SMCRv1 device instead. But
the resources assigned to the connection won't be reset.
When server tries SMCRv1 device, the connection creation process will
be executed again. Since conn->lnk has been assigned when trying SMCRv2,
it will not be set to the correct SMCRv1 link in
smcr_lgr_conn_assign_link(). So in such situation, conn->lgr points to
correct SMCRv1 link group but conn->lnk points to the SMCRv2 link
mistakenly.
Then in smc_clc_send_confirm_accept(), conn->rmb_desc->mr[link->link_idx]
will be accessed. Since the link->link_idx is not correct, the related
MR may not have been initialized, so crash happens.
| Try SMCRv2 device first
| |-> conn->lgr: assign existed SMCRv2 link group;
| |-> conn->link: assign existed SMCRv2 link (link_idx may be 1 in SMC_LGR_SYMMETRIC);
| |-> sndbuf & RMB creation fails, quit;
|
| Try SMCRv1 device then
| |-> conn->lgr: create SMCRv1 link group and assign;
| |-> conn->link: keep SMCRv2 link mistakenly;
| |-> sndbuf & RMB creation succeed, only RMB->mr[link_idx = 0]
| initialized.
|
| Then smc_clc_send_confirm_accept() accesses
| conn->rmb_desc->mr[conn->link->link_idx, which is 1], then crash.
v
This patch tries to fix this by cleaning conn->lnk before assigning
link. In addition, it is better to reset the connection and clean the
resources assigned if trying SMCRv2 failed in buffer creation or
registration. |
A command injection vulnerability in COMFAST CF-XR11 (firmware V2.7.2) exists in the multi_pppoe API, processed by the sub_423930 function in /usr/bin/webmgnt. The phy_interface parameter is not sanitized, allowing attackers to inject arbitrary commands via a POST request to /cgi-bin/mbox-config?method=SET§ion=multi_pppoe. When the action parameter is set to "one_click_redial", the unsanitized phy_interface is used in a system() call, enabling execution of malicious commands. This can lead to unauthorized access to sensitive files, execution of arbitrary code, or full device compromise. |
In the Linux kernel, the following vulnerability has been resolved:
firewire: net: fix use after free in fwnet_finish_incoming_packet()
The netif_rx() function frees the skb so we can't dereference it to

In the Linux kernel, the following vulnerability has been resolved:
remoteproc: imx_dsp_rproc: Add custom memory copy implementation for i.MX DSP Cores
The IRAM is part of the HiFi DSP.
According to hardware specification only 32-bits write are allowed
otherwise we get a Kernel panic.
Therefore add a custom memory copy and memset functions to deal with
the above restriction. |
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:
NFSD: Protect against send buffer overflow in NFSv2 READ
Since before the git era, NFSD has conserved the number of pages
held by each nfsd thread by combining the RPC receive and send
buffers into a single array of pages. This works because there are
no cases where an operation needs a large RPC Call message and a
large RPC Reply at the same time.
Once an RPC Call has been received, svc_process() updates
svc_rqst::rq_res to describe the part of rq_pages that can be
used for constructing the Reply. This means that the send buffer
(rq_res) shrinks when the received RPC record containing the RPC
Call is large.
A client can force this shrinkage on TCP by sending a correctly-
formed RPC Call header contained in an RPC record that is
excessively large. The full maximum payload size cannot be
constructed in that case. |
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix potential use-after-free when clear keys
Similar to commit c5d2b6fa26b5 ("Bluetooth: Fix use-after-free in
hci_remove_ltk/hci_remove_irk"). We can not access k after kfree_rcu()
call. |
In the Linux kernel, the following vulnerability has been resolved:
x86/MCE: Always save CS register on AMD Zen IF Poison errors
The Instruction Fetch (IF) units on current AMD Zen-based systems do not
guarantee a synchronous #MC is delivered for poison consumption errors.
Therefore, MCG_STATUS[EIPV|RIPV] will not be set. However, the
microarchitecture does guarantee that the exception is delivered within
the same context. In other words, the exact rIP is not known, but the
context is known to not have changed.
There is no architecturally-defined method to determine this behavior.
The Code Segment (CS) register is always valid on such IF unit poison
errors regardless of the value of MCG_STATUS[EIPV|RIPV].
Add a quirk to save the CS register for poison consumption from the IF
unit banks.
This is needed to properly determine the context of the error.
Otherwise, the severity grading function will assume the context is
IN_KERNEL due to the m->cs value being 0 (the initialized value). This
leads to unnecessary kernel panics on data poison errors due to the
kernel believing the poison consumption occurred in kernel context. |
In the Linux kernel, the following vulnerability has been resolved:
net: skb_partial_csum_set() fix against transport header magic value
skb->transport_header uses the special 0xFFFF value
to mark if the transport header was set or not.
We must prevent callers to accidentaly set skb->transport_header
to 0xFFFF. Note that only fuzzers can possibly do this today.

PCIe spec r6.0, sec 7.5.3.7, recommends that software program the same ASPM
Control value in all functions of multi-function devices.
Disable ASPM and free the pcie_link_state when any child function is
removed so we can discard the dangling pcie_link_state->downstream pointer
and maintain the same ASPM Control configuration for all functions.
