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-2025-61147 1 Struktur 1 Libde265 2026-03-24 6.2 Medium
strukturag libde265 commit d9fea9d wa discovered to contain a segmentation fault via the component decoder_context::compute_framedrop_table().
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-2023-6377 4 Debian, Redhat, Tigervnc and 1 more 11 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 8 more 2026-03-24 7.8 High
A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved.
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-2025-14905 1 Redhat 10 Directory Server, Directory Server E4s, Directory Server Eus and 7 more 2026-03-24 7.2 High
A flaw was found in the 389-ds-base server. A heap buffer overflow vulnerability exists in the `schema_attr_enum_callback` function within the `schema.c` file. This occurs because the code incorrectly calculates the buffer size by summing alias string lengths without accounting for additional formatting characters. When a large number of aliases are processed, this oversight can lead to a heap overflow, potentially allowing a remote attacker to cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE).
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
A remote attacker with user privileges for the webUI can use the setting of the TFTP Filename with a POST Request to trigger a stack-based Buffer Overflow, resulting in a DoS attack.
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.
CVE-2026-26948 1 Dell 1 Integrated Dell Remote Access Controller 8 2026-03-24 4.9 Medium
Dell Integrated Dell Remote Access Controller 9, 14G versions prior to 7.00.00.174, 15G and 16G versions prior to 7.10.90.00, contain an Exposure of Sensitive System Information Due to Uncleared Debug Information vulnerability.

CVE-2026-23269 1 Linux 1 Linux Kernel 2026-03-24 N/A
In the Linux kernel, the following vulnerability has been resolved: apparmor: validate DFA start states are in bounds in unpack_pdb Start states are read from untrusted data and used as indexes into the DFA state tables. The aa_dfa_next() function call in unpack_pdb() will access dfa->tables[YYTD_ID_BASE][start], and if the start state exceeds the number of states in the DFA, this results in an out-of-bound read. ================================================================== BUG: KASAN: slab-out-of-bounds in aa_dfa_next+0x2a1/0x360 Read of size 4 at addr ffff88811956fb90 by task su/1097 ...
