A heap-based buffer overflow vulnerability exists in MZ Automation libiec61850 up to version 1.6.1 in the function MmsMapping_varAccessSpecToObjectReference within the MMS Protocol Workflow component. The vulnerability arises from manipulation of the argument GetNamedVariableListAttributesResponse.itemId. Exploitation requires local access and no user interaction. The issue has been publicly disclosed, but no patch or vendor response is currently available.

A flaw was found in p11-kit. A local attacker, or one with equivalent access to a reachable RPC channel, could exploit an integer overflow vulnerability. By sending specially crafted messages, the attacker can cause the system to miscalculate memory allocation for nested attributes. This leads to a memory corruption issue, specifically a heap out-of-bounds write, which can crash the p11-kit RPC parsing process, resulting in a Denial of Service (DoS). This vulnerability is only exploitable on 32 bit systems.

A heap-buffer-overflow vulnerability exists in the nothings stb TrueType library, up to version 1.26, that is used for parsing TrueType font files. The vulnerability exists in the stbtt__GetGlyphShapeTT() function within the nothings stb_truetype.h library when parsing malformed TTF (TrueType Font) files. The vulnerability resides in the glyph data parsing path. An attacker can craft a malformed TTF file with an inflated endPtsOfContours value and truncate the remaining glyph data. When an application utilizing stb_truetype.h (such as various game engines or graphics software) attempts to load, bake, or render this malformed font via stbtt_GetGlyphShape(), the parser will attempt to read past the end of the glyph data buffer, triggering the out-of-bounds read.

llama.cpp builds b1886 through b7445 contain an integer overflow vulnerability in the LLaMA-Android JNI wrapper where the new_1batch() function multiplies sizeof(llama_seq_id) by an attacker-controlled n_seq_max parameter without overflow validation, causing heap buffer allocation to wrap and allocate insufficient memory. Attackers can exploit this by providing a crafted n_seq_max value through a malicious model file or JNI call to trigger heap corruption and achieve denial of service or arbitrary code execution on Android applications using the LLaMA-Android binding.

CVE-2026-67867 is a buffer overflow vulnerability in Systerel S2OPC version 1.7.3. It allows a remote attacker to cause a denial of service by exploiting the Alarm/Conditions wrapper when processing PublishResponse EventNotificationList data. The vulnerability has a high severity with a CVSS score of 7.5 and does not impact confidentiality or integrity but affects availability.

A heap-based buffer overflow vulnerability exists in lib60870-C version 2.4.0 within the server-side FileSegment ASDU encoding path. The flaw arises because the FileSegment_encode() function only validates the standalone segment length but does not check the remaining capacity of the current ASDU frame before encoding, potentially leading to memory corruption.
