CVE-2026-40614 1 Pjsip 2 Pjproject, Pjsip 2026-04-23 8.8 High
PJSIP is a free and open source multimedia communication library written in C. In 2.16 and earlier, there is a buffer overflow when decoding Opus audio frames due to insufficient buffer size validation in the Opus codec decode path. The FEC decode buffers (dec_frame[].buf) were allocated based on a PCM-derived formula: (sample_rate/1000) * 60 * channel_cnt * 2. At 8 kHz mono this yields only 960 bytes, but codec_parse() can output encoded frames up to MAX_ENCODED_PACKET_SIZE (1280) bytes via opus_repacketizer_out_range(). The three pj_memcpy() calls in codec_decode() copied input->size bytes without bounds checking, causing a heap buffer overflow.
CVE-2026-5450 2 Gnu, The Gnu C Library 2 Glibc, Glibc 2026-04-23 9.8 Critical
Calling the scanf family of functions with a %mc (malloc'd character match) in the GNU C Library version 2.7 to version 2.43 with a format width specifier with an explicit width greater than 1024 could result in a one byte heap buffer overflow.
CVE-2026-26111 1 Microsoft 22 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 19 more 2026-04-23 8 High

CVE-2026-22008 1 Oracle 3 Java Se, Jdk, Jre 2026-04-23 3.7 Low
Vulnerability in Oracle Java SE (component: Libraries). The supported version that is affected is Oracle Java SE: 25.0.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 Base Score 3.7 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N).
CVE-2026-33020 1 Saitoha 1 Libsixel 2026-04-23 7.1 High
libsixel is a SIXEL encoder/decoder implementation derived from kmiya's sixel. Versions 1.8.7 and prior contain an integer overflow which leads to a heap buffer overflow via sixel_frame_convert_to_rgb888() in frame.c, where allocation size and pointer offset computations for palettised images (PAL1, PAL2, PAL4) are performed using int arithmetic before casting to size_t. For images whose pixel count exceeds INT_MAX / 4, the overflow produces an undersized heap allocation for the conversion buffer and a negative pointer offset for the normalization sub-buffer, after which sixel_helper_normalize_pixelformat() writes the full image data starting from the invalid pointer, causing massive heap corruption confirmed by ASAN. An attacker providing a specially crafted large palettised PNG can corrupt the heap of the victim process, resulting in a reliable crash and potential arbitrary code execution. This issue has been fixed in version 1.8.7-r1.
CVE-2026-3994 1 Rui314 1 Mold 2026-04-22 5.3 Medium
A vulnerability was detected in rui314 mold up to 2.40.4. This issue affects the function mold::ObjectFilemold::X86_64::initialize_sections of the file src/input-files.cc of the component Object File Handler. Performing a manipulation results in heap-based buffer overflow. Attacking locally is a requirement. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2026-3713 1 Libpng 1 Libpng 2026-04-22 5.3 Medium
A flaw has been found in pnggroup libpng up to 1.6.55. Affected by this vulnerability is the function do_pnm2png of the file contrib/pngminus/pnm2png.c of the component pnm2png. This manipulation of the argument width/height causes heap-based buffer overflow. The attack is restricted to local execution. 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.
CVE-2026-3407 1 Yosyshq 1 Yosys 2026-04-22 3.3 Low
A vulnerability was determined in YosysHQ yosys up to 0.62. This affects the function Yosys::RTLIL::Const::set of the file kernel/rtlil.h of the component BLIF File Parser. This manipulation causes heap-based buffer overflow. It is possible to launch the attack on the local host. The exploit has been publicly disclosed and may be utilized. Applying a patch is the recommended action to fix this issue. It appears that the issue is not reproducible all the time.
CVE-2026-40706 1 Tuxera 1 Ntfs-3g 2026-04-22 8.4 High
In NTFS-3G 2022.10.3 before 2026.2.25, a heap buffer overflow exists in ntfs_build_permissions_posix() in acls.c that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered on the READ path (stat, readdir, open) when processing a security descriptor with multiple ACCESS_DENIED ACEs containing WRITE_OWNER from distinct group SIDs.
CVE-2026-6491 1 Libvips 1 Libvips 2026-04-22 5.3 Medium
A security vulnerability has been detected in libvips up to 8.18.2. The affected element is the function im_minpos_vec of the file libvips/deprecated/vips7compat.c of the component nip2 Handler. Such manipulation of the argument n leads to heap-based buffer overflow. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. The vendor confirms that they will "be removing the deprecated area in libvips 8.19".
CVE-2026-32135 2 Emqx, Nanomq 2 Nanomq, Nanomq 2026-04-22 7.5 High
NanoMQ MQTT Broker (NanoMQ) is an all-around Edge Messaging Platform. Versions prior to 0.24.11 have a remotely triggerable heap buffer overflow in the `uri_param_parse` function of NanoMQ's REST API. The vulnerability occurs due to an off-by-one error when allocating memory for query parameter keys and values, allowing an attacker to write a null byte beyond the allocated buffer. This can be triggered via a crafted HTTP request. Version 0.24.11 patches the issue.
CVE-2026-32961 1 Silextechnology 3 Amc Manager, Sd-330ac, Sd-330ac Firmware 2026-04-22 5.3 Medium
SD-330AC and AMC Manager provided by silex technology, Inc. contain a heap-based buffer overflow vulnerability in packet data processing of sx_smpd. Processing a crafted packet may cause a temporary denial-of-service (DoS) condition.
CVE-2026-32956 1 Silextechnology 3 Amc Manager, Sd-330ac, Sd-330ac Firmware 2026-04-22 9.8 Critical
SD-330AC and AMC Manager provided by silex technology, Inc. contain a heap-based buffer overflow vulnerability in processing the redirect URLs. Arbitrary code may be executed on the device.
CVE-2026-41445 1 Mborgerding 1 Kissfft 2026-04-22 8.8 High
KissFFT before commit 8a8e66e contains an integer overflow vulnerability in the kiss_fftndr_alloc() function in kiss_fftndr.c where the allocation size calculation dimOther*(dimReal+2)*sizeof(kiss_fft_scalar) overflows signed 32-bit integer arithmetic before being widened to size_t, causing malloc() to allocate an undersized buffer. Attackers can trigger heap buffer overflow by providing crafted dimensions that cause the multiplication to exceed INT_MAX, allowing writes beyond the allocated buffer region when kiss_fftndr() processes the data.
