CVE-2026-39103 Média · 5.5 CWE-122 05/05/2026
Heap-based Buffer Overflow em Gpac
Buffer Overflow vulnerability in GPAC before commit v391dc7f4d234988ea0bc3cc294eb725eddf8f702 allows an attacker to cause a denial of service via the src/scenegraph/svg_attributes.c, svg_parse_strings(), gf_svg_parse_attribute()
CVE-2026-29004 Alta · 8.1 CWE-122 04/05/2026
BusyBox DHCPv6 Client Heap Buffer Overflow via DNS_SERVERS
BusyBox before commit 42202bf contains a heap buffer overflow vulnerability in the DHCPv6 client (udhcpc6) DNS_SERVERS option handler in networking/udhcp/d6_dhcpc.c that allows network-adjacent attackers to trigger memory corruption by sending a crafted DHCPv6 response with a malformed D6_OPT_DNS_SERVERS option. Attackers can exploit incorrect heap buffer allocation calculations in the option_to_env() function to cause denial of service or achieve arbitrary code execution on embedded systems without heap hardening.

Buffer Overflow vulnerability exists in Assimp versions up to 6.0.2 in the FBX Importer. The vulnerability occurs in aiMaterial::AddBinaryProperty, where a property key string from a crafted FBX file is copied into a fixed-size heap buffer using strcpy() without runtime length validation
CVE-2026-5405 Alta · 7.8 CWE-122 30/04/2026
Heap-based Buffer Overflow in Wireshark
RDP protocol dissector crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service and possible code execution
CVE-2026-5403 Alta · 7.8 CWE-122 30/04/2026
Heap-based Buffer Overflow in Wireshark
SBC codec crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service and possible code execution
CVE-2026-42512 Alta · 8.1 CWE-122 30/04/2026
Remotely triggerable out-of-bounds heap write in dhclient
As dhclient is building an environment to pass to dhclient-script, it may need to resize the array of string pointers. The code which expands the array incorrectly calculates its new size when requesting memory, resulting in a heap buffer overrun. A specially crafted packet can cause dhclient to overrun its buffer of environment entries. This can result in a crash, but it may be possible to leverage this bug to achieve remote code execution.
CVE-2026-35547 Alta · 8.1 CWE-122 30/04/2026
Heap overflow in libnv
When processing the header of an incoming message, libnv failed to properly validate the message size. The lack of validation allows a malicious program to write outside the bounds of a heap allocation. This can trigger a crash or system panic, and it may be possible for an unprivileged user to exploit the bug to elevate their privileges.

Text::Minify::XS versions from 0.3.0 before 0.7.8 for Perl have heap overflow when processing some malformed UTF-8 characters
Text::Minify::XS versions from 0.3.0 before 0.7.8 for Perl have a heap overflow when processing some malformed UTF-8 characters. The minify functions mishandled some malformed UTF-8 characters, leading to heap corruption. Note that the minify_utf8 function is an alias for minify.
CVE-2026-33602 Alta · 8.2 CWE-122 22/04/2026
Off-by-one access when processing crafted UDP responses
A rogue backend can send a crafted UDP response with a query ID off by one related to the maximum configured value, triggering an out-of-bounds write leading to a denial of service.
CVE-2026-6846 Alta · 7.8 CWE-122 22/04/2026
Binutils: binutils: arbitrary code execution via malformed xcoff object file processing
A flaw was found in binutils. A heap-buffer-overflow vulnerability exists when processing a specially crafted XCOFF (Extended Common Object File Format) object file during linking. A local attacker could trick a user into processing this malicious file, which could lead to arbitrary code execution, allowing the attacker to run unauthorized commands, or cause a denial of service, making the system unavailable.
CVE-2026-40706 Alta · 8.4 CWE-122 21/04/2026
Heap-based Buffer Overflow em Tuxera Ntfs-3g
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-2026-40614 Alta · 8.8 CWE-122 21/04/2026
PJSIP: Heap buffer overflow in Opus codec decoding
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-2026-32135 Alta · 7.5 CWE-122 20/04/2026
NanoMQ has Heap Buffer Overflow in URI Parameter Parsing
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-2026-41445 Alta · 8.8 CWE-122 20/04/2026
KissFFT Integer Overflow Heap Buffer Overflow via kiss_fftndr_alloc()
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.
CVE-2026-32961 Média · 5.3 CWE-122 20/04/2026
SD-330AC and AMC Manager provided by silex technology, Inc. contain a heap-based buffer overflow...
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 Crítica · 9.8 CWE-122 20/04/2026
Estouro de buffer baseado em heap em SD-330AC e AMC Manager (silex technology)
SD-330AC e AMC Manager fornecidos pela silex technology, Inc. contêm uma vulnerabilidade de estouro de buffer baseado em heap no processamento de URLs de redirecionamento. Código arbitrário pode ser executado no dispositivo.
CVE-2026-35512 Alta · 8.8 CWE-122 17/04/2026
xrdp: Heap buffer overflow in EGFX channel
xrdp is an open source RDP server. Versions through 0.10.5 have a heap-based buffer overflow in the EGFX (graphics dynamic virtual channel) implementation due to insufficient validation of client-controlled size parameters, allowing an out-of-bounds write via crafted PDUs. Pre-authentication exploitation can crash the process, while post-authentication exploitation may achieve remote code execution. This issue has been fixed in version 0.10.6. If users are unable to immediately update, they should run xrdp as a non-privileged user (default since 0.10.2) to limit the impact of successful exploitation.
