CVE-2025-15608 1 Tp-link 1 Ax53 V1 2026-03-24 N/A
This vulnerability in AX53 v1 results from insufficient input sanitization in the device’s probe handling logic, where unvalidated parameters can trigger a stack-based buffer overflow that causes the affected service to crash and, under specific conditions, may enable remote code execution through complex heap-spray techniques. Successful exploitation may result in repeated service unavailability and, in certain scenarios, allow an attacker to gain control of the device.
CVE-2025-59383 1 Qnap Systems 1 Media Streaming Add-on 2026-03-24 N/A
A buffer overflow vulnerability has been reported to affect Media Streaming Add-On. The remote attackers can then exploit the vulnerability to modify memory or crash processes. We have already fixed the vulnerability in the following version: Media Streaming Add-on 500.1.1 and later
CVE-2026-33250 1 Longturn 1 Freeciv21 2026-03-24 7.5 High
Freeciv21 is a free open source, turn-based, empire-building strategy game. Versions prior to 3.1.1 crash with a stack overflow when receiving specially-crafted packets. A remote attacker can use this to take down any public server. A malicious server can use this to crash the game on the player's machine. Authentication is not needed and, by default, logs do not contain any useful information. All users should upgrade to Freeciv21 version 3.1.1. Running the server behind a firewall can help mitigate the issue for non-public servers. For local games, Freeciv21 restricts connections to the current user and is therefore not affected.
CVE-2026-33307 1 Airtower-luna 1 Mod Gnutls 2026-03-24 7.5 High
Mod_gnutls is a TLS module for Apache HTTPD based on GnuTLS. In versions prior to 0.12.3 and 0.13.0, code for client certificate verification imported the certificate chain sent by the client into a fixed size `gnutls_x509_crt_t x509[]` array without checking the number of certificates is less than or equal to the array size. `gnutls_x509_crt_t` is a `typedef` for a pointer to an opaque GnuTLS structure created using with `gnutls_x509_crt_init()` before importing certificate data into it, so no attacker-controlled data was written into the stack buffer, but writing a pointer after the last array element generally triggered a segfault, and could theoretically cause stack corruption otherwise (not observed in practice). Server configurations that do not use client certificates (`GnuTLSClientVerify ignore`, the default) are not affected. The problem has been fixed in version 0.12.3 by checking the length of the provided certificate chain and rejecting it if it exceeds the buffer length, and in version 0.13.0 by rewriting certificate verification to use `gnutls_certificate_verify_peers()`, removing the need for the buffer entirely. There is no workaround. Version 0.12.3 provides the minimal fix for users of 0.12.x who do not wish to upgrade to 0.13.0 yet.
CVE-2026-4535 1 Tenda 2 Fh451, Fh451 Firmware 2026-03-24 8.8 High
A vulnerability has been found in Tenda FH451 1.0.0.9. This vulnerability affects the function WrlclientSet of the file /goform/WrlclientSet. Such manipulation of the argument GO leads to stack-based buffer overflow. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.
CVE-2026-30871 1 Openwrt 1 Openwrt 2026-03-24 9.8 Critical
OpenWrt Project is a Linux operating system targeting embedded devices. In versions prior to 24.10.6 and 25.12.1, the mdns daemon has a Stack-based Buffer Overflow vulnerability in the parse_question function. The issue is triggered by PTR queries for reverse DNS domains (.in-addr.arpa and .ip6.arpa). DNS packets received on UDP port 5353 are expanded by dn_expand into an 8096-byte global buffer (name_buffer), which is then copied via an unbounded strcpy into a fixed 256-byte stack buffer when handling TYPE_PTR queries. The overflow is possible because dn_expand converts non-printable ASCII bytes (e.g., 0x01) into multi-character octal representations (e.g., \001), significantly inflating the expanded name beyond the stack buffer's capacity. A crafted DNS packet can exploit this expansion behavior to overflow the stack buffer, making the vulnerability reachable through normal multicast DNS packet processing. This issue has been fixed in versions 24.10.6 and 25.12.1.
CVE-2026-30872 1 Openwrt 1 Openwrt 2026-03-24 9.8 Critical
OpenWrt Project is a Linux operating system targeting embedded devices. In versions prior to 24.10.6 and 25.12.1, the mdns daemon has a Stack-based Buffer Overflow vulnerability in the match_ipv6_addresses function, triggered when processing PTR queries for IPv6 reverse DNS domains (.ip6.arpa) received via multicast DNS on UDP port 5353. During processing, the domain name from name_buffer is copied via strcpy into a fixed 256-byte stack buffer, and then the reverse IPv6 request is extracted into a buffer of only 46 bytes (INET6_ADDRSTRLEN). Because the length of the data is never validated before this extraction, an attacker can supply input larger than 46 bytes, causing an out-of-bounds write. This allows a specially crafted DNS query to overflow the stack buffer in match_ipv6_addresses, potentially enabling remote code execution. This issue has been fixed in versions 24.10.6 and 25.12.1.
CVE-2025-6021 2 Redhat, Xmlsoft 29 Discovery, Enterprise Linux, Enterprise Linux Eus and 26 more 2026-03-24 7.5 High
A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input.
CVE-2025-9820 1 Redhat 5 Ceph Storage, Enterprise Linux, Insights Proxy and 2 more 2026-03-24 4 Medium
A flaw was found in the GnuTLS library, specifically in the gnutls_pkcs11_token_init() function that handles PKCS#11 token initialization. When a token label longer than expected is processed, the function writes past the end of a fixed-size stack buffer. This programming error can cause the application using GnuTLS to crash or, in certain conditions, be exploited for code execution. As a result, systems or applications relying on GnuTLS may be vulnerable to a denial of service or local privilege escalation attacks.
CVE-2026-22316 1 Phoenixcontact 77 Fl Nat 2008, Fl Nat 2208, Fl Nat 2304-2gc-2sfp and 74 more 2026-03-24 6.5 Medium

CVE-2026-22318 1 Phoenixcontact 77 Fl Nat 2008, Fl Nat 2208, Fl Nat 2304-2gc-2sfp and 74 more 2026-03-24 4.9 Medium
A stack-based buffer overflow vulnerability in the device's file transfer parameter workflow allows a high-privileged attacker to send oversized POST parameters, causing memory corruption in an internal process, resulting in a DoS attack.
CVE-2026-22319 1 Phoenixcontact 77 Fl Nat 2008, Fl Nat 2208, Fl Nat 2304-2gc-2sfp and 74 more 2026-03-24 4.9 Medium
A stack-based buffer overflow in the device's file installation workflow allows a high-privileged attacker to send oversized POST parameters that overflow a fixed-size stack buffer within an internal process, resulting in a DoS attack.
CVE-2026-22320 1 Phoenixcontact 77 Fl Nat 2008, Fl Nat 2208, Fl Nat 2304-2gc-2sfp and 74 more 2026-03-24 6.5 Medium
A stack-based buffer overflow in the CLI's TFTP file‑transfer command handling allows a low-privileged attacker with Telnet/SSH access to trigger memory corruption by supplying unexpected or oversized filename input. Exploitation results in the corruption of the internal buffer, causing the CLI and web dashboard to become unavailable and leading to a denial of service.
CVE-2026-22321 1 Phoenixcontact 77 Fl Nat 2008, Fl Nat 2208, Fl Nat 2304-2gc-2sfp and 74 more 2026-03-24 5.3 Medium
A stack-based buffer overflow in the device's Telnet/SSH CLI login routine occurs when a unauthenticated attacker send an oversized or unexpected username input. An overflow condition crashes the thread handling the login attempt, forcing the session to close. Because other CLI sessions remain unaffected, the impact is limited to a low‑severity availability disruption.
