CVE-2026-42483 1 Hashcat 1 Hashcat 2026-05-02 7.3 High
A heap-based buffer overflow in the Kerberos hash parser in hashcat v7.1.2 allows an attacker to cause a denial of service or possibly execute arbitrary code via a crafted Kerberos hash file. The issue affects module_hash_decode in multiple Kerberos-related modules because account_info_len is calculated from untrusted delimiter positions without upper-bound validation before memcpy copies the data into a fixed-size account_info buffer.
CVE-2026-5403 1 Wireshark 1 Wireshark 2026-05-02 7.8 High
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-2026-6529 1 Wireshark 1 Wireshark 2026-05-01 5.5 Medium
iLBC audio codec crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service
CVE-2026-6530 1 Wireshark 1 Wireshark 2026-05-01 5.5 Medium
DCP-ETSI protocol dissector crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service
CVE-2026-5402 1 Wireshark 1 Wireshark 2026-05-01 8.8 High
TLS protocol dissector heap overflow in Wireshark 4.6.0 to 4.6.4 allows denial of service and possible code execution
CVE-2026-7378 1 Wireshark 1 Wireshark 2026-05-01 5.5 Medium
Crash in sharkd 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service
CVE-2026-5653 1 Wireshark 1 Wireshark 2026-05-01 5.5 Medium
DCP-ETSI protocol dissector crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service
CVE-2026-35547 1 Freebsd 1 Freebsd 2026-05-01 8.1 High
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.
CVE-2026-42512 1 Freebsd 1 Freebsd 2026-05-01 8.1 High
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-2026-22828 1 Fortinet 4 Fortianalyzer Cloud, Fortianalyzercloud, Fortimanager Cloud and 1 more 2026-05-01 7.3 High
A heap-based buffer overflow vulnerability in Fortinet FortiAnalyzer Cloud 7.6.2 through 7.6.4, FortiManager Cloud 7.6.2 through 7.6.4 may allow a remote unauthenticated attacker to execute arbitrary code or commands via specifically crafted requests. Successful exploitation would require a large amount of effort in preparation because of ASLR and network segmentation
CVE-2026-5474 1 Nasa 2 Cfs, Core Flight System 2026-04-30 6.3 Medium
A vulnerability was found in NASA cFS up to 7.0.0. This affects the function CFE_MSG_GetSize of the file apps/to_lab/fsw/src/to_lab_passthru_encode.c of the component CCSDS Packet Header Handler. Performing a manipulation results in heap-based buffer overflow. The attacker must have access to the local network to execute the attack. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2026-39363 2 Vitejs, Voidzero 3 Vite, Vite-plus, Vite\+ 2026-04-30 7.5 High
Vite is a frontend tooling framework for JavaScript. From 6.0.0 to before 6.4.2, 7.3.2, and 8.0.5, if it is possible to connect to the Vite dev server’s WebSocket without an Origin header, an attacker can invoke fetchModule via the custom WebSocket event vite:invoke and combine file://... with ?raw (or ?inline) to retrieve the contents of arbitrary files on the server as a JavaScript string (e.g., export default "..."). The access control enforced in the HTTP request path (such as server.fs.allow) is not applied to this WebSocket-based execution path. This vulnerability is fixed in 6.4.2, 7.3.2, and 8.0.5.
CVE-2026-7339 4 Apple, Google, Linux and 1 more 4 Macos, Chrome, Linux Kernel and 1 more 2026-04-30 8.8 High
Heap buffer overflow in WebRTC in Google Chrome prior to 147.0.7727.138 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-33298 1 Ggml 1 Llama.cpp 2026-04-30 7.8 High
llama.cpp is an inference of several LLM models in C/C++. Prior to b7824, an integer overflow vulnerability in the `ggml_nbytes` function allows an attacker to bypass memory validation by crafting a GGUF file with specific tensor dimensions. This causes `ggml_nbytes` to return a significantly smaller size than required (e.g., 4MB instead of Exabytes), leading to a heap-based buffer overflow when the application subsequently processes the tensor. This vulnerability allows potential Remote Code Execution (RCE) via memory corruption. b7824 contains a fix.
CVE-2026-7353 4 Apple, Google, Linux and 1 more 4 Macos, Chrome, Linux Kernel and 1 more 2026-04-30 8.3 High
Heap buffer overflow in Skia in Google Chrome prior to 147.0.7727.138 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
CVE-2026-2646 1 Wolfssl 1 Wolfssl 2026-04-29 8.1 High
A heap-buffer-overflow vulnerability exists in wolfSSL's wolfSSL_d2i_SSL_SESSION() function. When deserializing session data with SESSION_CERTS enabled, certificate and session id lengths are read from an untrusted input without bounds validation, allowing an attacker to overflow fixed-size buffers and corrupt heap memory. A maliciously crafted session would need to be loaded from an external source to trigger this vulnerability. Internal sessions were not vulnerable.
CVE-2026-3548 1 Wolfssl 1 Wolfssl 2026-04-29 9.8 Critical
Two buffer overflow vulnerabilities existed in the wolfSSL CRL parser when parsing CRL numbers: a heap-based buffer overflow could occur when improperly storing the CRL number as a hexadecimal string, and a stack-based overflow for sufficiently sized CRL numbers. With appropriately crafted CRLs, either of these out of bound writes could be triggered. Note this only affects builds that specifically enable CRL support, and the user would need to load a CRL from an untrusted source.
CVE-2026-5447 1 Wolfssl 1 Wolfssl 2026-04-29 7.5 High
Heap buffer overflow in CertFromX509 via AuthorityKeyIdentifier size confusion. A heap buffer overflow occurs when converting an X.509 certificate internally due to incorrect size handling of the AuthorityKeyIdentifier extension.
CVE-2026-5264 1 Wolfssl 1 Wolfssl 2026-04-29 9.8 Critical
Heap buffer overflow in DTLS 1.3 ACK message processing. A remote attacker can send a crafted DTLS 1.3 ACK message that triggers a heap buffer overflow.
CVE-2026-5448 1 Wolfssl 1 Wolfssl 2026-04-29 4.3 Medium
X.509 date buffer overflow in wolfSSL_X509_notAfter / wolfSSL_X509_notBefore. A buffer overflow may occur when parsing date fields from a crafted X.509 certificate via the compatibility layer API. This is only triggered when calling these two APIs directly from an application, and does not affect TLS or certificate verify operations in wolfSSL.
