| CVE-2004-0816 | 1 Linux | 1 Linux Kernel | 2026-06-16 | 5.0 MEDIUM | 7.5 HIGH |
| Integer underflow in the firewall logging rules for iptables in Linux before 2.6.8 allows remote attackers to cause a denial of service (application crash) via a malformed IP packet. | |||||
| CVE-2004-0184 | 1 Tcpdump | 1 Tcpdump | 2026-06-16 | 5.0 MEDIUM | N/A |
| Integer underflow in the isakmp_id_print for TCPDUMP 3.8.1 and earlier allows remote attackers to cause a denial of service (crash) via an ISAKMP packet with an Identification payload with a length that becomes less than 8 during byte order conversion, which causes an out-of-bounds read, as demonstrated by the Striker ISAKMP Protocol Test Suite. | |||||
| CVE-2026-54413 | 2026-06-16 | N/A | 8.2 HIGH | ||
| driftregion iso14229 through 0.9.0 contains an integer underflow and downstream out-of-bounds read in the Handle_0x27_SecurityAccess() function in iso14229.c that allows a remote unauthenticated attacker to crash a UDS server and potentially read memory past the receive buffer by sending a single-byte 0x27 SecurityAccess request that follows any earlier well-formed 0x27 message. The handler reads the SecurityAccess subFunction from recv_buf[1] without first checking that recv_len is at least 2, then computes the key-data length as the unsigned subtraction (uint16_t)(recv_len - UDS_0X27_REQ_BASE_LEN); when recv_len equals 1 the result underflows to 65535 and is passed as args.len to the application's SecAccessValidateKey or SecAccessRequestSeed callback, which typically iterates or copies that many bytes from the 4-KB receive buffer. Every other UDS sub-function handler in the library (0x10, 0x11, 0x14, 0x19, 0x22, 0x23, 0x28, and others) performs an explicit recv_len lower-bound check before indexing; Handle_0x27_SecurityAccess is the sole outlier. The vulnerable handler reaches over CAN bus, OBD-II, ISO-TP, and DoIP transports and is exposed in the default diagnostic session without prior authentication; deployments on automotive ECUs, industrial controllers, and IoT devices that ship iso14229 as their UDS server are affected. | |||||
| CVE-2026-54412 | 2026-06-16 | N/A | 8.2 HIGH | ||
| LiamBindle MQTT-C through version 1.1.6 contains a heap-based out-of-bounds read and integer underflow in the mqtt_unpack_publish_response() function in src/mqtt.c that allows a remote unauthenticated attacker controlling an MQTT broker - or able to inject MQTT traffic into an unencrypted session - to crash a subscribed MQTT-C client and potentially disclose adjacent heap memory by sending a single crafted PUBLISH packet. The function validates only that the fixed-header remaining_length is at least 4, then reads the 16-bit topic_name_size field from the broker-controlled packet and advances the parse pointer by that value without verifying that topic_name_size plus the surrounding overhead fits within remaining_length; it subsequently computes application_message_size as remaining_length - topic_name_size - 2 (QoS 0) or - 4 (QoS greater than 0) in unsigned arithmetic, producing an integer underflow that is then passed to memmove(). A PUBLISH packet with topic_name_size = 0xFFFF and remaining_length = 7 advances the parse pointer 65535 bytes past the receive buffer (out-of-bounds read) and causes an application_message_size near 2^32, crashing the process when the resulting memmove() is executed. | |||||
| CVE-2026-45999 | 1 Linux | 1 Linux Kernel | 2026-06-16 | N/A | 7.1 HIGH |
| In the Linux kernel, the following vulnerability has been resolved: erofs: fix unsigned underflow in z_erofs_lz4_handle_overlap() Some crafted images can have illegal (!partial_decoding && m_llen < m_plen) extents, and the LZ4 inplace decompression path can be wrongly hit, but it cannot handle (outpages < inpages) properly: "outpages - inpages" wraps to a large value and the subsequent rq->out[] access reads past the decompressed_pages array. However, such crafted cases can correctly result in a corruption report in the normal LZ4 non-inplace path. Let's add an additional check to fix this for backporting.

| CVE-2026-47222 | 2026-06-15 | N/A | 5.4 MEDIUM | ||
| NanaZip is the 7-Zip derivative intended for the modern Windows experience. From version 3.0.1000.0 to before version 6.0.1698.0, a heap out-of-bounds read exists in the Android Verified Boot (AVB) vbmeta image parser in NanaZip (via the upstream 7-Zip AvbHandler). An unsigned integer underflow in a bounds check allows an attacker-controlled value_num_bytes field to pass validation, causing AddNameToString to read up to ~4 GiB past the end of a 64 KiB heap buffer. This causes a deterministic crash (denial of service) when opening a crafted .avb or .img file. This issue has been patched in stable version 6.0.1698.0 and preview version 6.5.1742.0. | |||||
| CVE-2026-42542 | 1 Tdengine | 1 Tdengine | 2026-06-12 | N/A | 7.5 HIGH |
| TDengine is an open source, time-series database optimized for Internet of Things devices. In versions 3.4.0.0 through 3.4.1.5, an unauthenticated remote attacker can crash the taosd server process by sending a single crafted RPC packet. No credentials or prior session state are required. Version 3.4.1.6 fixes the issue. | |||||
| CVE-2026-11789 | 1 Redhat | 3 389 Directory Server, Directory Server, Enterprise Linux | 2026-06-12 | N/A | 4.9 MEDIUM |
| A flaw was found in 389 Directory Server. The SMD5 password storage plugin performs unsigned integer underflow when computing salt length from a crafted password hash shorter than 16 bytes, causing a buffer over-read that crashes the LDAP server during authentication. | |||||
| CVE-2026-11850 | 2026-06-12 | N/A | 5.0 MEDIUM | ||
| An integer underflow vulnerability was found in MIT krb5 in the berval2tl_data() function in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c. The function performs an unsigned subtraction (bv_len - 2) without a prior bounds check. When bv_len is 0 or 1, the subtraction wraps to a large value which is then truncated to uint16_t, yielding 0xFFFE (65534) or 0xFFFF (65535). The subsequent malloc succeeds and memcpy reads up to 65534 bytes from a 0-1 byte buffer, resulting in a heap out-of-bounds read. The attack vector involves a malicious or compromised LDAP KDB backend returning a krbExtraData attribute with bv_len < 2, triggering the underflow when the KDC or kadmind reads principal data. | |||||
| CVE-2026-42326 | 1 Imagemagick | 1 Imagemagick | 2026-06-11 | N/A | 5.1 MEDIUM |
| ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-47 and 7.1.2-22, when writing an IPTC output file a malicious input file could cause an out of bounds read of a single byte. This issue has been patched in versions 6.9.13-47 and 7.1.2-22. | |||||

| CVE-2026-49494 | 2026-06-08 | N/A | 7.5 HIGH | ||
| Comodo Internet Security's firewall driver Inspect.sys contains an integer underflow in its IPv6 packet parser. The parser decrements an unsigned 64-bit payload-length value (taken from the IPv6 fixed header's payload length field) by the size of each IPv6 extension header without validating it, so a packet whose declared payload length is smaller than the sum of its extension-header lengths underflows the value to a near-maximal 64-bit integer. Because IPv6 parsing occurs before firewall rule enforcement, a remote, unauthenticated attacker can send a single crafted IPv6 packet - even to a host with all ports blocked - to trigger an out-of-bounds read (and, on a separate code path, an oversized memcpy) in the Windows kernel at DISPATCH_LEVEL, crashing the system (BSOD). | |||||
| CVE-2026-33999 | 2026-06-08 | N/A | 7.8 HIGH | ||
| A flaw was found in the X.Org X server. This integer underflow vulnerability, specifically in the XKB compatibility map handling, allows an attacker with local or remote X11 server access to trigger a buffer read overrun. This can lead to memory-safety violations and potentially a denial of service (DoS) or other severe impacts. | |||||
| CVE-2026-50593 | 2026-06-05 | N/A | 7.3 HIGH | ||
| Graphite before 1.3.15 has an integer underflow and resultant out-of-bounds write via Graphite actions, because slotat does not ensure that an offset is within the allowed slot-map range. | |||||
| CVE-2026-35049 | 2026-06-04 | N/A | 6.5 MEDIUM | ||
| wire-ios is an iOS client for the Wire secure messaging application. Prior to version 4.16.0, upon receiving a crafted malicious Proteus external message with an encrypted payload that is shorter than 16 bytes, the Wire iOS client crashes. The crash is triggered automatically after message receival with no user interaction. Since the malicious message persists in the conversation, the app enters a crash loop on relaunch and cannot be reopened until the local state is wiped. This issue has been fixed with version 4.16.0 which introduces the missing length check and is available via the App Store. No known workarounds are available. | |||||
