CVSS v3.1 |
| NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer, where a user in a guest VM can cause a NULL-pointer dereference in the host. A successful exploit of this vulnerability may lead to denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
comedi: comedi_8255: Correct error in subdevice initialization
The refactoring done in commit 5c57b1ccecc7 ("comedi: comedi_8255: Rework
subdevice initialization functions") to the initialization of the io
field of struct subdev_8255_private broke all cards using the
drivers/comedi/drivers/comedi_8255.c module.
Prior to 5c57b1ccecc7, __subdev_8255_init() initialized the io field
in the newly allocated struct subdev_8255_private to the non-NULL
callback given to the function, otherwise it used a flag parameter to
select between subdev_8255_mmio and subdev_8255_io. The refactoring
removed that logic and the flag, as subdev_8255_mm_init() and
subdev_8255_io_init() now explicitly pass subdev_8255_mmio and
subdev_8255_io respectively to __subdev_8255_init(), only
__subdev_8255_init() never sets spriv->io to the supplied
callback. That spriv->io is NULL leads to a later BUG:

| A nil pointer dereference in PingCAP TiDB v8.2.0-alpha-216-gfe5858b allows attackers to crash the application via expression.inferCollation. |
| Vulnerability of null references in the motor module.Successful exploitation of this vulnerability may affect availability. |
| A vulnerability in the DHCP version 4 (DHCPv4) server feature of Cisco IOS XR Software could allow an unauthenticated, remote attacker to trigger a crash of the dhcpd process, resulting in a denial of service (DoS) condition.
This vulnerability exists because certain DHCPv4 messages are improperly validated when they are processed by an affected device. An attacker could exploit this vulnerability by sending a malformed DHCPv4 message to an affected device. A successful exploit could allow the attacker to cause a crash of the dhcpd process. While the dhcpd process is restarting, which may take approximately two minutes, DHCPv4 server services are unavailable on the affected device. This could temporarily prevent network access to clients that join the network during that time period and rely on the DHCPv4 server of the affected device.
Notes:
Only the dhcpd process crashes and eventually restarts automatically. The router does not reload.
This vulnerability only applies to DHCPv4. DHCP version 6 (DHCPv6) is not affected. |
| NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability where a user may cause a NULL-pointer dereference by accessing passed parameters the validity of which has not been checked. A successful exploit of this vulnerability may lead to denial of service and limited information disclosure. |
| An attacker who successfully exploited these vulnerabilities could cause the robot to stop.
A vulnerability exists in the PROFINET stack included in the RobotWare versions listed below.
This vulnerability arises under specific condition when specially crafted message is processed by the system.
Below are reported vulnerabilities in the Robot Ware versions.

| In the Linux kernel, the following vulnerability has been resolved:
sfc: fix TX channel offset when using legacy interrupts
In legacy interrupt mode the tx_channel_offset was hardcoded to 1, but
that's not correct if efx_sepparate_tx_channels is false. In that case,
the offset is 0 because the tx queues are in the single existing channel
at index 0, together with the rx queue.
Without this fix, as soon as you try to send any traffic, it tries to
get the tx queues from an uninitialized channel getting these errors:

| CWE-476 NULL Pointer Dereference vulnerability in the evalExpr() function of GoAhead Web Server (version <= 6.0.0) when compiled with the ME_GOAHEAD_JAVASCRIPT flag. This vulnerability allows a remote attacker with the privileges to modify JavaScript template (JST) files to trigger a crash and cause a Denial of Service (DoS) by providing malicious templates. |
| in OpenHarmony v5.0.2 and prior versions allow a local attacker cause DOS through NULL pointer dereference. |
| An attacker can publish a zone containing specific Resource Record Sets. Processing and caching results for these sets can lead to an illegal memory accesses and crash of the Recursor, causing a denial of service.
The remedy is: upgrade to the patched 5.2.1 version.
We would like to thank Volodymyr Ilyin for bringing this issue to our attention. |
| A vulnerability classified as critical was found in RT-Thread 5.1.0. This vulnerability affects the function csys_sendto of the file rt-thread/components/lwp/lwp_syscall.c. The manipulation of the argument to leads to null pointer dereference. |
| Substance3D - Viewer versions 0.22 and earlier are affected by a NULL Pointer Dereference vulnerability that could lead to application denial-of-service. An attacker could exploit this vulnerability to crash the application, causing disruption in service. Exploitation of this issue requires user interaction in that a victim must open a malicious file. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Pass non-null to dcn20_validate_apply_pipe_split_flags
[WHAT & HOW]
"dcn20_validate_apply_pipe_split_flags" dereferences merge, and thus it
cannot be a null pointer. Let's pass a valid pointer to avoid null
dereference.
This fixes 2 FORWARD_NULL issues reported by Coverity. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check null pointers before using them
[WHAT & HOW]
These pointers are null checked previously in the same function,
indicating they might be null as reported by Coverity. As a result,
they need to be checked when used again.
This fixes 3 FORWARD_NULL issue reported by Coverity. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check null pointers before used
[WHAT & HOW]
Poniters, such as dc->clk_mgr, are null checked previously in the same
function, so Coverity warns "implies that "dc->clk_mgr" might be null".
As a result, these pointers need to be checked when used again.
This fixes 10 FORWARD_NULL issues reported by Coverity. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check null pointers before multiple uses
[WHAT & HOW]
Poniters, such as stream_enc and dc->bw_vbios, are null checked previously
in the same function, so Coverity warns "implies that stream_enc and
dc->bw_vbios might be null". They are used multiple times in the
subsequent code and need to be checked.
This fixes 10 FORWARD_NULL issues reported by Coverity. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null check for head_pipe in dcn201_acquire_free_pipe_for_layer
This commit addresses a potential null pointer dereference issue in the
`dcn201_acquire_free_pipe_for_layer` function. The issue could occur
when `head_pipe` is null.
The fix adds a check to ensure `head_pipe` is not null before asserting
it. If `head_pipe` is null, the function returns NULL to prevent a
potential null pointer dereference.
Reported by smatch:
