| CVE-2026-16512 | 1 Zephyrproject | 1 Zephyr | 2026-09-19 | 3.1 Low |
| gptp_handle_msg() in subsys/net/l2/ethernet/gptp/gptp.c dereferenced the gPTP header returned by GPTP_HDR() and switched on hdr->message_type without first checking that the received frame carries at least sizeof(struct gptp_hdr) (34) bytes of payload. The header accessor gptp_get_hdr() deliberately never fails for a short buffer — it returns pkt->frags->data and leaves validation to its callers — so a truncated frame produced a header pointer covering memory beyond the received data. The per-message-type checks that follow do not compensate: GPTP_VALID_LEN() reduces to len > 60 once the Ethernet header has been pulled, which is false for every fixed-size gPTP message, so GPTP_CHECK_LEN() never rejects a truncated SYNC, FOLLOWUP, PDELAY_RESP or SIGNALING message. The defect is reached by an unauthenticated peer on the same link sending an Ethernet frame with ethertype 0x88F7 to the PTP multicast address on an interface configured as a gPTP port, with CONFIG_NET_GPTP enabled. Because conformant Ethernet pads frames to 60 bytes, a payload shorter than 34 bytes generally requires a link that can deliver sub-minimum frames — for example the native_sim TAP driver (drivers/ethernet/eth_native_tap.c), which forwards whatever length the host device supplies, or a MAC configured to accept undersized frames. The short packet is retained (net_pkt_ref() into rcvd_sync_ptr, rcvd_follow_up_ptr, rcvd_pdelay_resp_ptr or rcvd_announce_ptr) and later parsed by the media-dependent and media-independent state machines in subsys/net/l2/ethernet/gptp/gptp_md.c and subsys/net/l2/ethernet/gptp/gptp_mi.c, which read tens of further bytes and copy some of them (the announce priority vector, hdr->port_id) into state that is subsequently transmitted. Under the default fixed-size buffer allocator (CONFIG_NET_BUF_FIXED_DATA_SIZE, 128-byte fragments) the accesses stay inside the allocated fragment and disclose stale recycled buffer contents; under the experimental CONFIG_NET_BUF_VARIABLE_DATA_SIZE allocator, where fragments are heap-allocated at the exact frame length, they are genuine out-of-bounds reads. There is no write and no availability impact. | ||||
| CVE-2026-16514 | 1 Zephyrproject | 1 Zephyr | 2026-09-19 | 4.3 Medium |
| gptp_mi_qualify_announce() in subsys/net/l2/ethernet/gptp/gptp_mi.c walks the Path Trace TLV of a received IEEE 802.1AS Announce message, comparing each clock identity against the local one. The loop bound was taken solely from the attacker-controlled wire field announce->steps_removed (accepted up to 254), never from announce->tlv.len, which is the field that states how many identities the TLV actually carries. Because path_sequence is the flexible member of the wire TLV (struct gptp_path_trace_tlv) and GPTP_ANNOUNCE() yields a raw pointer into the received packet buffer, the memcmp() inside the loop can address memory well past the end of the received frame. The stack's only length validation, GPTP_ANNOUNCE_CHECK_LEN(), requires the received gPTP payload to be exactly 68 + tlv.len bytes — so it does not constrain the loop, it guarantees the data is absent. An unauthenticated attacker on the same Ethernet segment can send a single Announce frame declaring tlv.len = 0 with steps_removed = 254; the frame passes the length check and reception path (net_gptp_recv() → gptp_handle_msg() → gptp_mi_qualify_announce()), which performs no authentication, and the loop then reads 255 entries of 8 bytes each — about 2 KB — beyond the end of the network buffer. The impact is an out-of-bounds read. The bytes read are only used as a memcmp() operand and are never returned to the attacker, so there is no meaningful information disclosure; the practical risk is that the overread crosses a network buffer pool boundary into unmapped or MPU-protected memory and faults the networking RX thread, causing a denial of service. Exposure is limited to builds that enable the opt-in, experimental CONFIG_NET_GPTP (TSN/AVB deployments) and to attackers with layer-2 adjacency, since gPTP frames are sent to a link-local multicast address and are not routed. The fix computes the true entry count as tlv.len / GPTP_CLOCK_ID_LEN and rejects the announce when steps_removed + 1 exceeds it, so the loop can no longer run past the data the packet-length check proved present. | ||||
| CVE-2026-93372 | 1 Google | 1 Chrome | 2026-09-19 | 9.6 Critical |
| Buffer overflow in WebGL in Google Chrome on on Android prior to 153.0.8010.52 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Critical) | ||||
| CVE-2026-90137 | 1 Linux | 1 Linux Kernel | 2026-09-18 | 7.7 High |
| In the Linux kernel, the following vulnerability has been resolved: platform/x86: hp-bioscfg: fix password encoding bounds check The password PSWD_ENCODINGS parser reads password_obj[elem + pos_values] while copying the supported password encodings from the ACPI package. The outer loop only guarantees that elem is within password_obj_count. The encoding count is bounded by MAX_ENCODINGS_SIZE, but that does not guarantee that the ACPI package contains enough entries for all elem + pos_values accesses. A malformed package can therefore declare a non-zero encoding count without providing enough string objects, causing the parser to read past the ACPI package array and pass an out-of-bounds string pointer and length to hp_convert_hexstr_to_str(). Add the same computed-index bounds check used by the other offset-based package parsing loops before reading password_obj[elem + pos_values]. | ||||
| CVE-2026-59181 | 1 Academysoftwarefoundation | 1 Openimageio | 2026-09-18 | 6.1 Medium |
| OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1, A crafted cineon file can supply a numberofelements value greater than the format maximum of eight. cineoninput::open() uses that unchecked value as the loop bound while filling the fixed strings[8] array, writing pointers beyond the stack buffer and into adjacent state, resulting in memory corruption and denial of service. The affected implementation is identified by src/cineon.imageio/cineoninput.cpp, CineonInput::open(), numberOfElements, and strings[8], which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1. | ||||
| CVE-2026-73863 | 1 Nanomq | 1 Nanomq | 2026-09-18 | N/A |
| NanoMQ is an MQTT broker. Prior to 0.24.14, NanoMQ's broker-side MQTT v5 nmq_subinfo_decode() function in nng/src/sp/protocol/mqtt/mqtt_parser.c reuses len_of_varint from the outer Properties Length while parsing each SUBSCRIPTION_IDENTIFIER. A remote client can send a SUBSCRIBE packet with a multi-byte Properties Length and repeated subscription identifiers, causing get_var_integer() to begin at an incorrect offset and read beyond the heap message buffer. The flaw is reachable through the broker receive path and can crash the broker, while the separately reported topic-option off-by-one occurs later and is not this vulnerability. This issue is fixed in version 0.24.14. | ||||
| CVE-2026-93740 | 1 Totolink | 1 A3002mu | 2026-09-18 | 10 Critical |
| A vulnerability was identified in Totolink A3002MU Hh-B20211125.1046. Affected is the function formWlEncrypt of the file /boafrm/formWlEncrypt. The manipulation of the argument submit-url leads to buffer overflow. It is possible to initiate the attack remotely. The exploit is publicly available and might be used. | ||||
| CVE-2026-48977 | 1 Openslide | 1 Openslide | 2026-09-18 | N/A |
| OpenSlide is a C library for reading whole slide image files. From 3.4.1 until 4.0.1, OpenSlide's parse_level0_xml() processing in src/openslide-vendor-ventana.c accepts nonpositive row or column tile counts from a crafted Ventana BIF file. The invalid counts produce attacker-controlled relative memory offsets and allow arbitrary values to be written at those offsets, affecting all supported platforms and configurations and resulting in a crash or potential arbitrary code execution. This issue is fixed in version 4.0.1. | ||||
| CVE-2026-81176 | 1 Svelte | 1 Devalue | 2026-09-18 | 5.3 Medium |
| Svelte devalue is a JavaScript library that serializes values into strings when JSON.stringify isn't sufficient for the job. Prior to 5.9.2, devalue.parse does not reject out-of-bounds indices that are greater than or equal to values.length in src/parse.js. A specially crafted untrusted payload can make the parser alternate between array representations, producing quadratic work as the payload grows and causing denial of service in applications that parse untrusted devalue data. This issue is fixed in version 5.9.2. | ||||

| CVE-2026-63451 | 2026-09-18 | 3.3 Low | ||
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, a locally supplied detection rule that combines frame inspection without content and a transformed match without content can make src/detect-engine-prefilter.c select multiple non-prefilter frame engines while preparing signatures for non-prefilter inspection. Loading the crafted rule, including in test mode, can trigger a heap buffer overflow and crash Suricata; network traffic alone cannot reach the flaw. This issue is fixed in version 8.0.6. | ||||
| CVE-2026-61721 | 2026-09-18 | 8 High | ||
| FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.5.0 until 2.5.6, the native DLS loader assigns file-controlled wsmp.loop_start and wsmp.loop_length values to samples without calling fluid_sample_validate() or fluid_sample_sanitize_loop(). A crafted DLS file can place sample loop points beyond the sample buffer, causing out-of-bounds reads during audio rendering, undefined behavior, possible memory disclosure, and denial of service. Builds compiled with the CMake option enable-native-dls set to OFF do not expose the affected parser. This issue is fixed in version 2.5.6. | ||||
| CVE-2026-57228 | 2026-09-18 | 8.2 High | ||
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 7.0.13 until 7.0.17, the SMTP MIME quoted-printable decoder in src/util-decode-mime.c can read one byte past a heap buffer when a quoted-printable escape sequence is split across traffic chunks and the following chunk contains exactly one byte. Crafted SMTP traffic can trigger the out-of-bounds read and crash Suricata when decode-quoted-printable MIME decoding is enabled. This issue is fixed in version 7.0.17. | ||||
| CVE-2026-54627 | 1 Happyseafox | 1 Sail | 2026-09-18 | 9.8 Critical |
| SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. In 0.9.10 and earlier, psd_private_sail_pixel_format() in src/sail-codecs/psd/helpers.c resolves a one-channel PSD in Bitmap color mode to SAIL_PIXEL_FORMAT_BPP1_INDEXED without requiring the file depth to be one, so the pixel buffer uses one-bit rows while sail_codec_load_frame_v8_psd() in src/sail-codecs/psd/psd.c accepts depth == 8 and writes one attacker-controlled byte per pixel. Loading a crafted PSD through sail_load_from_file() or sail_load_from_memory() therefore writes beyond each heap row, causing memory corruption, a reliable crash, or potential code execution. This mode/depth mismatch is distinct from GHSA-rcqx-gc76-r9mv and GHSA-wcj8-hxxf-pq2c. This issue is fixed in version 1.0.0. | ||||
| CVE-2026-25294 | 1 Qualcomm | 1 Snapdragon | 2026-09-18 | 7.4 High |
