CVE-2026-15028 1 Redhat 3 Enterprise Linux, Hummingbird, Openshift 2026-09-21 3.9 Low
A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive. The issue occurs during the parsing of a PAX extended header containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system.
CVE-2026-44236 1 Alanxz 1 Rabbitmq-c 2026-09-21 7.1 High
rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to 0.16.0, a malicious AMQP server can send an undersized connection.tune.frame_max value during amqp_login(), and rabbitmq-c accepts the value in amqp_login_inner() in librabbitmq/amqp_socket.c. amqp_tune_connection() in librabbitmq/amqp_connection.c uses frame_max to reallocate the outbound buffer without enforcing AMQP_FRAME_MIN_SIZE. Immediate serialization of connection.tune-ok through amqp_frame_to_bytes() writes beyond the undersized heap allocation, causing memory corruption and likely denial of service. An on-path attacker can also trigger the flaw against plaintext AMQP traffic. Code execution is theoretically possible but was not demonstrated. This issue is fixed in version 0.16.0.
CVE-2026-94424 1 Moore Threads 1 Mtt S80 Driver Package 2026-09-21 8.8 High
A vulnerability has been found in Moore Threads MTT S80 Driver Package up to 340.150. Impacted is the function sub_140001000 in the library mtdispkm64.sys of the component IOCTL Handler. The manipulation leads to heap-based buffer overflow. An attack has to be approached locally. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-90439 2 F5, Redhat 3 Nginx Open Source, Nginx Plus, Hummingbird 2026-09-18 6.5 Medium
NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_v3_module module. When using HTTP/3 with OpenSSL versions <= OpenSSL 3.5.0 under certain configurations, a limited heap buffer overflow could happen while processing a TLS handshake. This can happen in a non-deterministic manner that is beyond the attacker's control. This may cause a heap buffer overflow in the NGINX worker process leading to a restart and/or limited data corruption. Impact: This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system or limited data corruption. There is no control plane exposure; this is a data plane issue only. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
CVE-2026-81665 2 Corosync, Redhat 7 Corosync, Enterprise Linux, Enterprise Linux Eus and 4 more 2026-09-18 7.5 High
A heap-based buffer overflow was found in Corosync's Totem Process Group (totempg) message reassembly. When processing fragmented multicast messages, the buffer used to reassemble fragments lacks a runtime bounds check in release builds. A network-adjacent attacker able to send crafted multicast protocol messages to the cluster could cause a heap buffer overflow with attacker-controlled data. This can crash the Corosync daemon, causing a denial of service to the entire cluster, and may potentially allow further exploitation given sufficient heap-corruption control.
CVE-2026-81477 2026-09-18 7.2 High
Dell OpenManage Server Administrator, versions prior to 11.1.0.3, contains a Heap-based Buffer Overflow vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Code execution.
CVE-2026-92958 1 Patriksimek 1 Vm2 2026-09-17 8.5 High
vm2 through 3.11.6 contains a builtin-module denylist bypass in NodeVM. When the embedder uses the builtin wildcard together with negative entries (e.g. require: { builtin: ['*', '-fs', '-child_process'] }), negative entries are matched by exact module name in lib/builtin.js, so -fs removes only the builtin named fs and does not remove builtin subpaths such as fs/promises. Sandboxed code can therefore call require('fs/promises') or require('node:fs/promises') and reach the promise-based filesystem API despite fs being denied; node: prefix handling is likewise inconsistent (a -node:fs/promises entry does not block require('fs/promises')). Host file creation and writing were confirmed via fsp.writeFile(), and other fs/promises operations (cp, mkdir, rename, rm, rmdir, truncate, read operations, etc.) are also reachable. This issue is fixed in vm2 3.11.7.
CVE-2026-50696 1 Microsoft 15 Windows 10 1809, Windows 10 21h2, Windows 10 21h2 and 12 more 2026-09-17 7.5 High
Heap-based buffer overflow in Windows Internet Key Exchange (IKE) Protocol allows an unauthorized attacker to deny service over a network.
CVE-2026-93381 2026-09-17 N/A
Buffer overflow in PDFium in Google Chrome on on Windows prior to 153.0.8010.52 allowed a remote attacker leveraging social engineering to potentially execute arbitrary code inside the sandbox via a crafted PDF file. (Chromium security severity: High)
CVE-2026-81634 1 Nlnetlabs 1 Unbound 2026-09-17 7.5 High
In NLnet Labs Unbound up to and including 1.26.0, a 255 length query name with a large TCP response can lead to a heap buffer overflow during the RRSet canonicalisation routine. This is caused by missing to add the first owner name into the buffer length check. A malicious actor operating a malicious name server or tampering with an incoming response to Unbound (canonicalisation happens before DNSSEC validation), can trigger the vulnerability.
CVE-2026-81642 1 Nlnetlabs 1 Unbound 2026-09-17 9.8 Critical
In NLnet Labs Unbound up to and including 1.26.0, a vulnerability was found in the DNSSEC validator that enables denial of service and possible remote code execution as a result of digesting DNSKEYs. A DNSKEY with an owner compression pointer to its own RDATA can overflow the digest buffer. Remote code execution is possible through attacker controlled data. An adversary can exploit the vulnerability by controlling a malicious zone and querying a vulnerable Unbound.
CVE-2026-82717 1 Nlnetlabs 1 Unbound 2026-09-17 8.1 High
In NLnet Labs Unbound up to and including 1.26.0, a vulnerability was found in that can progressively corrupt heap memory and under certain systems and compilation options could lead to remote code execution. The vulnerability starts when CNAME synthesis during an upstream response needs to enforce(rewrite) a max TTL value in the packet buffer. Coupled with a compression pointer that points to the overwritten value and invalidates the domain name, it leads to an error path that does not properly move the buffer position and allows for the heap buffer overflow. Since this is heavily reliant on heap memory layout, results are memory corruption that eventually leads to a crash and under specific systems and compilation options remote code execution.
CVE-2026-89028 1 Mikrotik 1 Routeros 2026-09-17 7.5 High
MikroTik RouterOS before 7.24 contains a heap memory corruption vulnerability in the userspace SMB daemon that allows remote attackers to corrupt adjacent heap memory by supplying a crafted uniPwdLen value in the SMB1 SessionSetupAndX handler. An attacker can send a malformed SMB1 request with a uniPwdLen field that triggers an integer underflow, causing the resulting value to be used as the copy length in a memory copy operation into a smaller heap buffer, corrupting adjacent heap memory.
CVE-2026-72967 1 Microsoft 26 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 23 more 2026-09-17 7.8 High

CVE-2026-73023 1 Microsoft 26 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 23 more 2026-09-17 8.8 High
Heap-based buffer overflow in Windows Imaging Component allows an unauthorized attacker to execute code over a network.
CVE-2026-73024 1 Microsoft 26 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 23 more 2026-09-17 7.8 High
Heap-based buffer overflow in Windows Services for NFS ONCRPC XDR Driver allows an authorized attacker to elevate privileges locally.
CVE-2026-54559 1 Cmusphinx 1 Pocketsphinx 2026-09-17 N/A
PocketSphinx is a small speech recognizer. Prior to 5.1.1, the trie language-model loaders in src/lm/ngram_model_trie.c do not adequately validate boundary conditions in ARPA, DMP, and binary format headers, and the acoustic-model loaders in src/mdef.c and src/util/bio.c use sscanf with unbounded string fields. Loading an invalid, corrupted, or malicious language or acoustic model can therefore cause stack or heap buffer overflows and memory corruption. An attacker who can write to a directory selected by POCKETSPHINX_PATH can replace or add a model file that PocketSphinx later loads; users of PocketSphinx 5prealpha have no backported patch and must migrate to the fixed release. This issue is fixed in version 5.1.1.
