| A 32-bit integer wraparound in the MongoDB C Driver's Windows-only Kerberos/SSPI authentication code can cause an undersized heap buffer to be allocated when an excessively long credential value is supplied in the client's connection configuration. A party able to control that client-side configuration, in conjunction with the affected authentication mechanism, can cause the driver to write outside the bounds of the allocated buffer. This may result in corruption of client process memory and denial of service of the client application. The issue affects only client builds compiled with the Windows-native authentication backend. |
| An Integer Overflow vulnerability in the DPI certificate scanner in Juniper Networks Session Smart Router allows an unauthenticated remote attacker to cause a denial of service via a specially crafted TLS server certificate. |
| An integer overflow in the remote-control
screen processing component of TeamViewer clients (Full Client, Portable and Remote
Control App) prior to version 15.83 may allow a malicious remote host to cause
a denial of service or, depending on the platform, potentially execute
arbitrary code with the privileges of the viewer process. Exploitation requires
a user to establish a remote-control session to an attacker-controlled or
compromised host. |
| In EPICS Base release 7.0.10 and prior, an integer overflow in network request processing can cause memory to be allocated with an incorrect size. Subsequent handling of attacker supplied data may result in memory corruption, denial of service, or potential remote code execution. |
| In EPICS Base release 7.0.10 and prior, an improper validation of message length values during protocol parsing can trigger an integer overflow, resulting in an out-of-bounds memory write. Successful exploitation can cause process instability or denial of service. |
| Integer overflow or wraparound in Windows Resource Management (MRM) allows an authorized attacker to elevate privileges locally. |
| Integer overflow or wraparound in Microsoft Office Outlook allows an unauthorized attacker to execute code over a network. |
| Integer overflow or wraparound in Windows Background Intelligent Transfer Service (BITS) allows an authorized attacker to elevate privileges locally. |
| Integer overflow or wraparound in Windows Kernel Mode Driver allows an unauthorized attacker to elevate privileges with a physical attack. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: SEV: Ignore Port I/O requests of length '0'
Explicitly ignore Port I/O requests of length '0' (or count '0'), so that
setting up the software scratch area (and other code) doesn't have to
worry about underflowing the length, and to allow for WARNing on trying
to configure the scratch area with len==0. |
| Heap-based buffer overflow in Microsoft Windows Media Foundation allows an unauthorized attacker to execute code over a network. |
| Exposure of sensitive information to an unauthorized actor in Windows Client Side Caching driver (csc.sys) allows an authorized attacker to disclose information locally. |
| Heap-based buffer overflow in Windows Win32K - GRFX allows an authorized attacker to elevate privileges locally. |
| Integer overflow or wraparound in Windows PowerShell allows an authorized attacker to execute code locally. |
| Dell PowerProtect Data Domain, Feature Release versions 7.7.1.0 through 8.8, LTS2024 release versions 7.13.1.0 through 7.13.1.80, LTS2025 release versions 8.3.1.0 through 8.3.1.40, LTS2026 release versions 8.6.1.0 through 8.6.1.20, contain an Integer Overflow or Wraparound vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Code execution. |

| ProtobufParser parses length-prefixed protobuf string and bytes fields by checking (_inputPtr + len) <= _inputEnd and then, on the fast path, calling _finishShortText(len). Both use 32-bit signed integer arithmetic. When an attacker supplies a varint decoding to a length near Integer.MAX_VALUE, _inputPtr + len overflows to a negative value, the bounds check passes, and _finishShortText(len) reaches TextBuffer.expandCurrentSegment(len), which performs Arrays.copyOf with no cap and throws OutOfMemoryError: Requested array size exceeds VM limit.
The JVM refuses arrays larger than Integer.MAX_VALUE - 8 before consulting available heap, so -Xmx tuning does not mitigate the issue. StreamReadConstraints.maxStringLength and maxDocumentLength do not gate this path: a 33-byte payload is far below any document-length cap and the string-length check does not fire before the allocation. This was confirmed empirically against shipping artifacts with maxStringLength, maxDocumentLength and maxNestingDepth all configured.
A February 2026 hardening commit added the equivalent overflow guard to the packed-array-length and message-length paths but left the string-length call sites unguarded. No privileges or user interaction beyond the ability to submit data for parsing are required. |
| Assimp through 6.0.5 contains an integer overflow vulnerability in MD2Importer::ValidateHeader() that allows attackers to bypass frame table bounds checks using crafted header fields. Attackers can supply a malicious .md2 file whose numFrames and numVertices values wrap the 32-bit size check, causing heap out-of-bounds reads that crash applications or expose adjacent heap memory. |
| ProtobufParser._readStringKey() reads the length prefix of a protobuf map entry's string key into an attacker-controlled int and then checks (_inputPtr + len) <= _inputEnd using signed arithmetic. For values near Integer.MAX_VALUE the addition overflows to a negative value and the check passes even when the input contains no key data. The parser then calls _finishShortText(len), which expands the text buffer to the declared length via TextBuffer.expandCurrentSegment and Arrays.copyOf, throwing OutOfMemoryError: Requested array size exceeds VM limit.
An 8-byte malformed message containing a map entry with a declared key length of 0x7FFFFFFF is sufficient. Configured StreamReadConstraints, including maxStringLength, maxNameLength, maxDocumentLength and maxNestingDepth, do not prevent the failure. Applications running with -XX:+ExitOnOutOfMemoryError terminate the JVM.
This is the same integer-overflow pattern addressed for other call sites in the remediation associated with CVE-2026-104016 and CVE-2026-104017; the map-key call site was corrected on the 3.x branches only, leaving the corresponding 2.x branches unguarded. Release lines 2.18, 2.19 and 2.20 do not contain _readStringKey() and are not affected by this vector. No privileges or user interaction beyond the ability to submit data for parsing are required. The 3.0 release line and 3.1.0-3.1.5 / 3.2.0-3.2.1 do not contain _readStringKey() and are therefore not affected; the method first appears in 3.1.6 and 3.2.2, mirroring its introduction at 2.21.6 on the 2.x side. |
| In the Linux kernel, the following vulnerability has been resolved:
calipso: keep BIG TCP payload_len in calipso_skbuff_setattr()
calipso_skbuff_setattr() adjusts payload_len by the length of the
option it inserts or resizes:
payload = ntohs(ip6_hdr->payload_len);
ip6_hdr->payload_len = htons(payload + len_delta);
GRO can build BIG TCP packets larger than IPV6_MAXPLEN, and stores
payload_len == 0 for them; ipv6_payload_len() then falls back to
skb->len. For such a packet forwarded to a destination mapped to
CALIPSO, the code above writes len_delta (or 65536 + len_delta when
shrinking) into payload_len, and ipv6_payload_len() no longer falls
back to skb->len. nf_tables, conntrack and sch_cake rely on it.
The same arithmetic also wraps when a packet grows past IPV6_MAXPLEN,
and a BIG TCP packet that shrinks below IPV6_MAXPLEN should get its
real length back.
Set payload_len from the skb length with ipv6_set_payload_len(), which
stores 0 above IPV6_MAXPLEN and the real length otherwise, as
ipv6_gro_complete() does. The network header was just reset to
skb->data, so skb->len - sizeof(*ip6_hdr) is the payload length.
Tested on one kernel (arm64, QEMU) with SELinux permissive, a minimal
mdp-generated policy (network_peer_controls=1), "netlabelctl calipso
add pass doi:16" and a NetLabel mapping of fd00:2::/64 to CALIPSO
DOI 16. calipso_skbuff_setattr() was called through
netlbl_skbuff_setattr() from a test-only debugfs hook (not part of
this patch) adding a level-only label; payload_len after the call:
case before fix after fix real length
1000, unlabeled 1016 1016 1016
70000 GSO, payload_len 0 16 0 70016
65530 GSO, grows past MAXPLEN 10 0 65546
65540 GSO with a 24 byte hop
header, shrinks below MAXPLEN 65528 65532 65532
1000 with a 24 byte hop header 992 992 992
(0 means ipv6_payload_len() returns the real length.) On the forward
path, with a client injecting unlabeled UDP through a router to a
server, the router adds the CALIPSO option and the server delivers all
datagrams (Udp6InDatagrams 5, Ip6InTruncatedPkts 0) with this patch. |
