CVE-2026-67873 1 Mz-automation 1 Lib60870 2026-08-07 9.8 Critical
A heap-based buffer overflow exists in lib60870-C 2.4.0 in the server-side FileSegment ASDU encoding path. The issue occurs because FileSegment_encode() validates only the standalone segment length via FileSegment_GetMaxDataSize() and does not verify the residual capacity of the current ASDU frame before encoding object fields and segment data
CVE-2026-20311 1 Cisco 1 Ios Xe Software 2026-08-07 6.3 Medium
A vulnerability in the web-based management interface of Cisco IOS XE Software could allow an authenticated, remote attacker with low privileges to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient error handling in the web-based management interface. An attacker could exploit this vulnerability by authenticating with a malformed certificate. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.
CVE-2026-19026 1 Hdfgroup 1 Hdf5 2026-08-07 5.5 Medium
H5Z__filter_nbit in H5Znbit.c in HDF5 through 2.3.0 dereferences cd_values[0] through cd_values[4] without validating that cd_values is non-NULL or that cd_nelmts is at least 5, the fixed size of the filter's header. This allows attackers to cause a denial of service via a crafted HDF5 file that stores the N-Bit filter pipeline message with zero client-data values, opened and read via H5Dread, e.g. by the h5ls or h5repack tools.
CVE-2026-19027 1 Hdfgroup 1 Hdf5 2026-08-07 5.6 Medium
The H5Z__nbit_decompress_one_byte, H5Z__nbit_decompress_one_nooptype, and H5Z__nbit_decompress_one_atomic functions in H5Znbit.c in HDF5 through 2.3.0 advance a read index into the compressed chunk buffer without bounding it against the buffer's actual size. This allows attackers to cause an out-of-bounds heap read, and in constrained cases disclosure of adjacent heap memory into decompressed dataset values, via a crafted HDF5 file whose N-Bit filter parameters describe more decompressed data than the stored compressed chunk actually contains, triggered via H5Dread, e.g. by the h5ls or h5repack tools.
CVE-2026-19028 1 Hdfgroup 1 Hdf5 2026-08-07 5.5 Medium
H5Z__filter_fletcher32 in H5Zfletcher32.c in HDF5 through 2.3.0 computes the data length to checksum by subtracting the 4-byte trailing checksum size from the input buffer size without checking that the buffer is at least 4 bytes, allowing a size_t underflow. This allows attackers to cause a denial of service (massively out-of-bounds read and application crash in H5_checksum_fletcher32) via a crafted HDF5 file with a Fletcher32-filtered chunk smaller than 4 bytes, triggered via H5Dread, e.g. by the h5ls or h5dump tools.
CVE-2026-64573 1 Linux 1 Linux Kernel 2026-08-07 7.0 High
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: qca: fix NVM tag length underflow in TLV parser In the TLV_TYPE_NVM branch of qca_tlv_check_data() the tag loop bound is "while (idx < length - sizeof(struct tlv_type_nvm))". "length" is a signed int from the firmware TLV header and sizeof(struct tlv_type_nvm) is a size_t (12), so "length" is converted to size_t and any firmware-supplied "length" < 12 makes the subtraction wrap to a huge value. The loop body then reads a 12-byte struct tlv_type_nvm past the end of the short vmalloc'd firmware buffer (and the EDL_TAG_ID_* handlers can write past it). Rewrite the bound as "idx + sizeof(struct tlv_type_nvm) <= length"; both operands are non-negative, so it no longer underflows and a "length" too small for one record correctly skips the loop.

CVE-2020-37121 1 Codeblocks 2 Code::blocks, Code\\ 2026-08-06 5.5 Medium
CODE::BLOCKS 16.01 contains a buffer overflow vulnerability that allows attackers to execute arbitrary code by overwriting Structured Exception Handler with crafted Unicode characters. Attackers can create a malicious text file with 1982 bytes of buffer and shellcode to trigger remote code execution.
CVE-2026-67864 1 Open62541 1 Open62541 2026-08-06 7.5 High
An issue in open62541 v.1.5.5 and before allows a remote attacker to cause a denial of service via the NodeManagement type-instantiation logic component
CVE-2026-67871 1 Systerel 1 S2opc 2026-08-06 7.5 High
Buffer Overflow vulnerability in Systerel S2OPC 1.7.3 allows a remote attacker to cause a denial of service via the AddNodes, address_space_bs.c, sopc_node_mgt_helper_internal.c, and toolkit_test_server
CVE-2026-67866 1 Systerel 1 S2opc 2026-08-06 7.5 High
Buffer Overflow vulnerability in Systerel S2OPC 1.7.3 allows a remote attacker to cause a denial of service via the LockedStaMac_ProcessMsg_DeleteMonitoredItemsResponse and SOPC_StaMac_NewDeleteMonitoredItems in the client wrapper DeleteMonitoredItems path
CVE-2026-56210 2 Aomedia, Redhat 7 Libaom, Ai Inference Server, Enterprise Linux and 4 more 2026-08-06 7.1 High
A heap-buffer-overflow read vulnerability was found in libaom, the reference AV1 codec implementation. A missing bounds check in the SVC (Scalable Video Coding) layer ID control function allows setting a spatial_layer_id exceeding the configured number of layers. This causes an out-of-bounds heap read of approximately 40,728 bytes when computing a layer context array index. An attacker who can influence SVC encoder parameters in a network-facing service could exploit this for information disclosure (heap content leak) or denial of service (segmentation fault from hitting unmapped memory).
CVE-2026-67867 1 Systerel 1 S2opc 2026-08-06 7.5 High
Buffer Overflow vulnerability in Systerel S2OPC 1.7.3 allows a remote attacker to cause a denial of service via the Alarm/Conditions wrapper when processing PublishResponse EventNotificationList data
CVE-2026-67865 1 Systerel 1 S2opc 2026-08-06 7.5 High
S2OPC 1.7.3 contains an out-of-bounds read in RepublishResponse handling. This allows a remote attacker to cause a denial of service
CVE-2026-55980 1 Secureage 1 Catchpulse 2026-08-06 5.5 Medium
A denial-of-service vulnerability in CatchPulse could allow an attacker to conduct a stack buffer overrun attack, leading to a denial-of-service condition.
CVE-2026-67869 1 Open62541 1 Open62541 2026-08-06 7.5 High
Buffer Overflow vulnerability in open62541 v1.5.5 allows a remote attacker to cause a denial of service via the Service_Call validates input arguments against runtime-resolved InputArguments metadata
CVE-2026-71314 1 Nuxt 1 Nuxt 2026-08-06 7.5 High
Nuxt is an open-source web development framework for Vue.js. From 3.1.0 until 3.21.10 and 4.5.1, an unauthenticated attacker can use a server island v-for prop, including vforToArray and , to trigger unbounded SSR memory allocation until MAX_VFOR_LENGTH = 100000 and crash the Nuxt process. This issue is fixed in 3.21.10 and 4.5.1.
CVE-2026-24076 1 Qualcomm 1 Snapdragon 2026-08-06 6.7 Medium
Memory Corruption when processing registry values with incorrect types using a direct query method.
CVE-2026-67673 2026-08-05 4.6 Medium
A stack-based buffer overflow vulnerability exists in the cmd_edl function of OreSat Firmware v1.0. The vulnerability is triggered when processing the edl fw_flash command, where the <filename> argument is copied to a 64-byte stack buffer via memcpy without proper length validation. An attacker with physical access to the UART3 serial interface can exploit this vulnerability by sending a maliciously crafted command with an oversized filename parameter,
CVE-2026-55767 1 Guzzlephp 1 Guzzle 2026-08-05 5.8 Medium
Guzzle is an extensible PHP HTTP client. Prior to 7.12.1, CookieJar incorrectly accepts cookies with a dot-only Domain attribute and whitespace-padded variants. SetCookie::matchesDomain() removes leading dots from the cookie domain, normalizing dot-only values to the empty string; SetCookie::validate() only rejected a strictly empty domain, so these cookies could be stored and the empty normalized domain was treated as matching any request host. An attacker-controlled origin that an application requests with a shared cookie jar can therefore set a cookie that Guzzle later sends to unrelated hosts using the same jar. This may allow cookie injection or session fixation against downstream services, depending on how those services interpret the injected cookie. This vulnerability is fixed in 7.12.1.
CVE-2026-67860 1 Open62541 1 Open62541 2026-08-05 7.5 High
open62541 1.5.5 contains a heap-based buffer overflow in the default HistoryRead path when the default history database is used with the memory backend.
