CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
accel/ethosu: check MMIO mapping errors in probe
devm_platform_ioremap_resource() returns an error pointer when the register
resource cannot be mapped. ethosu_probe() stores it and continues until
initialization dereferences it through MMIO accessors.
Return the mapping error before initializing the device. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: midi2: Fix null-pointer dereference in f_midi2_free_ep_reqs
A null-pointer dereference occurs in f_midi2_free_ep_reqs() when attempting
to clean up an endpoint that was never initialized.
When configuring the MIDI 2.0 gadget via configfs and setting the block
direction to SNDRV_UMP_DIR_INPUT, the initialization of the midi1_ep_out
endpoint is explicitly skipped during the gadget bind phase
(f_midi2_bind()). As a result, the usb_ep->card field remains NULL.
Later, when the host sets the alternate setting, f_midi2_set_alt()
unconditionally stops both the IN and OUT endpoints by calling
f_midi2_stop_eps(), which in turn calls f_midi2_free_ep_reqs() for both
endpoints. When f_midi2_free_ep_reqs() is called for the uninitialized
midi1_ep_out, it attempts to dereference usb_ep->card to determine the
number of requests to free, leading to a crash.
Fix this by using usb_ep->num_reqs instead of usb_ep->card->info.num_reqs
in f_midi2_free_ep_reqs(). usb_ep->num_reqs is correctly set during
f_midi2_init_ep() and remains 0 if the endpoint was never initialized,
safely avoiding the loop. For consistency, apply the same change to
f_midi2_alloc_ep_reqs().
Oops: general protection fault, probably for non-canonical address

| FreeRDP before 3.31.0 contains a null pointer dereference vulnerability in gdi_surface_bits when processing Surface Bits commands with NSCodec codec ID. A malicious RDP server can crash a FreeRDP client by sending a crafted Surface Bits command claiming to use NSCodec, even when the codec is disabled. |
| Sandbox escape due to invalid pointer in the Graphics component. This vulnerability was fixed in Firefox 156, Firefox ESR 140.16, Firefox ESR 153.3, Thunderbird 156, Thunderbird 140.16, and Thunderbird 153.3. |
| resdata is software for reading and writing result files from the Eclipse reservoir simulator. Prior to 6.2.9, resdata insufficiently validates numeric fields, grid dimensions, keyword sizes, and array indexes while parsing untrusted GRDECL files in lib/resdata/rd_kw_grdecl.cpp and lib/resdata/rd_grid.cpp. Malformed COORD, ZCORN, CORSNUM, ACTNUM, or MAPAXES data can reach rd_grid_alloc_GRDECL_kw__ with inconsistent lengths, while unbounded floating-point conversion can exceed the intended parser buffer. In a network service that accepts untrusted GRDECL files, these conditions can cause a classic buffer overflow, out-of-bounds reads, invalid array access, NULL pointer dereference, memory corruption, or service termination. This issue is fixed in version 6.2.9. |
| Netcore NR255-V version 1.5.130703 contains a null pointer dereference vulnerability in the QoS setter CGI handlers filter_conn_del_cgi.c and gre_prio_set_cgi.c due to unchecked atoi() results. An attacker can trigger the flaw by supplying crafted input to these handlers, causing a denial of service. |
| Netcore NR255-V version 1.5.130703 contains a null pointer dereference vulnerability in route_policy_add.cgi caused by a missing exit_port parameter. Attackers can send requests lacking the exit_port field to trigger the null pointer dereference, resulting in a denial of service. |
| An attacker can cause `named` to abort by sending a crafted DNS-over-HTTPS request with a cryptographically invalid SIG(0) record, and then closing the transport connection prematurely.
This issue affects BIND 9 versions 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, and 9.20.9-S1 through 9.20.27-S1. |
| H.245 protocol dissector crash in 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18 allows denial of service |
| Bluetooth BR/EDR FHS protocol dissector crash in 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18 allows denial of service |
| A flaw was found in libxml2. A local user or an attacker providing a specially crafted XML catalog can trigger a NULL pointer dereference during XML catalog parsing. This occurs when a `nextCatalog` element lacks its mandatory `catalog` attribute, leading to the application crashing and causing a Denial of Service (DoS). |
| A vulnerability was detected in GNU Binutils 2.47. Affected by this vulnerability is the function elf_x86_allocate_dynrelocs of the file bfd/elfxx-x86.c of the component Dynamic Relocation Allocation. The manipulation results in null pointer dereference. The attack requires a local approach. The exploit is now public and may be used. Upgrading to version 2.48 addresses this issue. The patch is identified as d1268210b6f6/471130b39c0/283d3198bed/0a84e560216/a692a633d40. Upgrading the affected component is recommended. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: vgic-its: Don't dereference a NULL collection on ITT save
MAPC with V=0 drops ite->collection but leaves the ITE on the device's
ITT list, and vgic_its_save_ite() dereferences it unconditionally. A
guest that issues MAPD, MAPTI and then MAPC(V=0) therefore oopses the
host when the VMM issues KVM_DEV_ARM_ITS_SAVE_TABLES to migrate it.
That sequence is UNPREDICTABLE per the architecture, but KVM already
handles the resulting state in the translate, MOVI and DISCARD paths.
Save a zeroed entry, which vgic_its_restore_ite() reads back as
invalid. Skipping the ITE instead would leave the ITT slot holding
whatever is in guest memory, and restore rejects an entry naming a
collection the restored collection table does not have. |
| undici's WebSocket client crashes the whole Node.js process during the opening handshake when a server responds with a subprotocol that the client never requested. A default WebSocket connection sends no subprotocol, but if the server's 101 response includes a Sec-WebSocket-Protocol header, undici dereferences a null value while checking it against the requested list and throws an uncaught TypeError. Because that code runs inside a microtask with no surrounding error handling, the exception propagates and terminates the process under Node's default behavior, instead of gracefully failing the connection as required by the WebSocket protocol. Any application that opens a WebSocket to an attacker-controlled or compromised server, or over a plaintext connection subject to a machine-in-the-middle, can be crashed remotely without authentication in the default configuration. This affects undici versions from 6.7.0 up to 6.28.1, from 7.0.0 up to 7.29.1, and from 8.0.0 up to 8.10.2. Users should upgrade to undici 6.28.1, 7.29.1, or 8.10.2. |
| A security issue exists in MongoDB's 2dsphere index key generation that can cause a server crash due to a null pointer dereference. When a specially crafted GeoJSON document is inserted into a collection with a 2dsphere index, an inconsistency in geometry parsing can leave an internal object in an invalid, partially initialized state. During subsequent index key generation, access to this improperly initialized object results in a null pointer dereference that terminates the mongod process. An authenticated user with write access can use this to cause a denial of service. |
| Mikrotik RouterOs 6.44.5 (long-term tree) suffers from a memory corruption vulnerability in the /nova/bin/console process. An authenticated remote attacker can cause a Denial of Service (NULL pointer dereference). |
| A vulnerability was identified in GPAC up to f1219cde. The impacted element is the function gf_sg_mfurl_del of the file scenegraph/vrml_tools.c of the component MP4Box. The manipulation leads to null pointer dereference. Local access is required to approach this attack. The exploit is publicly available and might be used. This product adopts a rolling release strategy to maintain continuous delivery. Therefore, version details for affected or updated releases cannot be specified. Upgrading to version abi-16.23 is sufficient to resolve this issue. The identifier of the patch is 49dee5cad329cfed310c1682703df7daa47df31a. It is recommended to upgrade the affected component. |
| Null pointer dereference in Skype for Business allows an authorized attacker to deny service over a network. |
| Envoy Gateway is an open source project for managing Envoy Proxy as a standalone or Kubernetes-based application gateway. Prior to 1.7.4 and 1.8.1, translateSecurityPolicyForRoute in internal/gatewayapi/securitypolicy.go dereferences a nil authorization value when a namespace-scoped tenant creates a SecurityPolicy targeting a TCPRoute and omits spec.authorization. The persistent object triggers the panic on every reconcile; recovery in message/watchutil.go keeps the process alive but unwinds the runner/runner.go handle callback, stalling controller-wide xDS and infrastructure intermediate-representation publishing until an administrator deletes the object. The data plane continues to serve the last known good configuration while publication is stalled. This issue is fixed in versions 1.7.4 and 1.8.1. |
| A vulnerability was found in Open5GS up to 2.8.0. This affects the function ogs_pfcp_parse_volume_measurement in the library lib/pfcp/types.c of the component PFCP Handler. The manipulation results in null pointer dereference. The attack may be launched remotely. The patch is identified as 8f07b507b78ff94776f2cd49276eb116ed93d7f2. A patch should be applied to remediate this issue. |
