| In the Linux kernel, the following vulnerability has been resolved:
idpf: Fix RSS LUT NULL ptr issue after soft reset
During soft reset, the RSS LUT is freed and not restored unless the
interface is up. If an ethtool command that accesses the rss lut is
attempted immediately after reset, it will result in NULL ptr
dereference. Also, there is no need to reset the rss lut if the soft reset
does not involve queue count change.
After soft reset, set the RSS LUT to default values based on the updated
queue count only if the reset was a result of a queue count change and
the LUT was not configured by the user. In all other cases, don't touch
the LUT.
Steps to reproduce:
** Bring the interface down (if up)
ifconfig eth1 down
** update the queue count (eg., 27->20)
ethtool -L eth1 combined 20
** display the RSS LUT
ethtool -x eth1

| Null pointer dereference in Windows LDAP - Lightweight Directory Access Protocol allows an unauthorized attacker to deny service over a network. |
| The application does not validate the presence of required appearance (AP) data before accessing stamp annotation resources. When a PDF contains a stamp annotation missing its AP entry, the code continues to dereference the associated object without a prior null or validity check, which allows a crafted document to trigger a null pointer dereference and crash the application, resulting in denial of service. |
| In systemd 260 before 261, a local unprivileged user can trigger an assert via an IPC API call with an array or map that has a null element. |
| Cairo through 1.18.4, as used in Poppler through 25.08.0, has an "unscaled->face == NULL" assertion failure for _cairo_ft_unscaled_font_fini in cairo-ft-font.c. |
| A vulnerability, which was classified as problematic, has been found in Khronos Group glslang 15.1.0. Affected by this issue is the function glslang::TIntermediate::isConversionAllowed of the file glslang/MachineIndependent/Intermediate.cpp. The manipulation leads to null pointer dereference. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. |
| NVIDIA HD Audio Driver for Windows contains a vulnerability where an attacker could exploit a NULL pointer dereference issue. A successful exploit of this vulnerability might lead to a denial of service. |
| OpenFHE through 1.2.3 has a NULL pointer dereference in BinFHEContext::EvalFloor in lib/binfhe-base-scheme.cpp. |
| A flaw has been found in omec-project UPF up to 2.1.3-dev. This affects the function handleSessionEstablishmentRequest of the file /pfcpiface/pfcpiface/messages_session.go of the component PFCP Session Establishment Request Handler. This manipulation causes null pointer dereference. The attack may be initiated remotely. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet. |
| If a DHCPv4 client sends a request with some specific options, and Kea fails to find an appropriate subnet for the client, the `kea-dhcp4` process will abort with an assertion failure. This happens only if the client request is unicast directly to Kea; broadcast messages do not cause the problem.
This issue affects Kea versions 2.7.1 through 2.7.9, 3.0.0, and 3.1.0. |
| A vulnerability has been identified in SIMATIC CP 1242-7 V2 (incl. SIPLUS variants) (All versions < V3.5.20), SIMATIC CP 1243-1 (incl. SIPLUS variants) (All versions < V3.5.20), SIMATIC CP 1243-1 DNP3 (incl. SIPLUS variants) (All versions < V3.5.20), SIMATIC CP 1243-1 IEC (incl. SIPLUS variants) (All versions < V3.5.20), SIMATIC CP 1243-7 LTE (All versions < V3.5.20), SIMATIC CP 1243-8 IRC (6GK7243-8RX30-0XE0) (All versions < V3.5.20), SIMATIC HMI Comfort Panels (incl. SIPLUS variants) (All versions), SIMATIC IPC DiagBase (All versions), SIMATIC IPC DiagMonitor (All versions), SIMATIC WinCC Runtime Advanced (All versions), SIPLUS TIM 1531 IRC (6AG1543-1MX00-7XE0) (All versions < V2.4.8), TIM 1531 IRC (6GK7543-1MX00-0XE0) (All versions < V2.4.8). The web server of the affected devices do not properly handle the shutdown or reboot request, which could lead to the clean up of certain resources.
This could allow a remote attacker with elevated privileges to cause a denial of service condition in the system. |
| A Null Pointer Dereference vulnerability exists in the TON Virtual Machine (TVM) within the TON Blockchain before v2025.06. The issue is located in the execution logic of the INMSGPARAM instruction, where the program fails to validate if a specific pointer is null before accessing it. By sending a malicious transaction or smart contract, an attacker can trigger this null pointer dereference, causing the validator node process to crash (segmentation fault). This results in a Denial of Service (DoS) affecting the availability of the entire blockchain network. |
| In raw\TCP.cpp in Matter (aka connectedhomeip or Project CHIP) through 1.4.0.0 before 27ca6ec, there is a NULL pointer dereference in TCPBase::ProcessSingleMessage via TCP packets with zero messageSize, leading to denial of service. |
| A null pointer dereference vulnerability exists in the IOMap64.sys driver of ASUS AI Suite 3. The vulnerability can be triggered by a specially crafted input, which may lead to a system crash (BSOD). Refer to the '
Security Update for for AI Suite 3
' section on the ASUS Security Advisory for more information. |
| Sante PACS Server HTTP Content-Length Header Handling NULL Pointer Dereference Denial-of-Service Vulnerability. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Sante PACS Server. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of HTTP Content-Length header. The issue results from the lack of proper validation of a pointer prior to accessing it. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-26770. |
| 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:
net: core: prevent NULL deref in generic_hwtstamp_ioctl_lower()
The ethtool tsconfig Netlink path can trigger a null pointer
dereference. A call chain such as:
tsconfig_prepare_data() ->
dev_get_hwtstamp_phylib() ->
vlan_hwtstamp_get() ->
generic_hwtstamp_get_lower() ->
generic_hwtstamp_ioctl_lower()
results in generic_hwtstamp_ioctl_lower() being called with
kernel_cfg->ifr as NULL.
The generic_hwtstamp_ioctl_lower() function does not expect
a NULL ifr and dereferences it, leading to a system crash.
Fix this by adding a NULL check for kernel_cfg->ifr in
generic_hwtstamp_ioctl_lower(). If ifr is NULL, return -EINVAL. |
| A vulnerability has been identified in SIMATIC CP 1242-7 V2 (incl. SIPLUS variants) (All versions < V3.5.20), SIMATIC CP 1243-1 (incl. SIPLUS variants) (All versions < V3.5.20), SIMATIC CP 1243-1 DNP3 (incl. SIPLUS variants) (All versions < V3.5.20), SIMATIC CP 1243-1 IEC (incl. SIPLUS variants) (All versions < V3.5.20), SIMATIC CP 1243-7 LTE (All versions < V3.5.20), SIMATIC CP 1243-8 IRC (6GK7243-8RX30-0XE0) (All versions < V3.5.20), SIMATIC HMI Comfort Panels (incl. SIPLUS variants) (All versions), SIMATIC IPC DiagBase (All versions), SIMATIC IPC DiagMonitor (All versions), SIMATIC WinCC Runtime Advanced (All versions), SIPLUS TIM 1531 IRC (6AG1543-1MX00-7XE0) (All versions < V2.4.8), TIM 1531 IRC (6GK7543-1MX00-0XE0) (All versions < V2.4.8). The web server of the affected devices do not properly handle certain requests, causing a timeout in the watchdog, which could lead to the clean up of pointers.
This could allow a remote attacker to cause a denial of service condition in the system. |
| ECMA-262 is the language specification for the scripting language ECMAScript. A problem in the ECMAScript (JavaScript) specification of async generators, introduced by a May 2021 spec refactor, may lead to mis-implementation in a way that could present as a security vulnerability, such as type confusion and pointer dereference.
The internal async generator machinery calls regular promise resolver functions on IteratorResult (`{ done, value }`) objects that it creates, assuming that the IteratorResult objects will not be then-ables. Unfortunately, these IteratorResult objects inherit from `Object.prototype`, so these IteratorResult objects can be made then-able, triggering arbitrary behaviour, including re-entering the async generator machinery in a way that violates some internal invariants.
The ECMAScript specification is a living standard and the issue has been addressed at the time of this advisory's public disclosure. JavaScript engine implementors should refer to the latest specification and update their implementations to comply with the `AsyncGenerator` section.
