CVE-2025-26595 3 Redhat, Tigervnc, X.org 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2026-06-29 7.8 High
A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size.
CVE-2024-12084 8 Almalinux, Archlinux, Gentoo and 5 more 9 Almalinux, Arch Linux, Linux and 6 more 2026-06-29 9.8 Critical
A heap-based buffer overflow flaw was found in the rsync daemon. This issue is due to improper handling of attacker-controlled checksum lengths (s2length) in the code. When MAX_DIGEST_LEN exceeds the fixed SUM_LENGTH (16 bytes), an attacker can write out of bounds in the sum2 buffer.
CVE-2025-13502 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-06-29 7.5 High
A flaw was found in WebKitGTK and WPE WebKit. This vulnerability allows an out-of-bounds read and integer underflow, leading to a UIProcess crash (DoS) via a crafted payload to the GLib remote inspector server.
CVE-2025-11021 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2026-06-29 7.5 High
A flaw was found in the cookie date handling logic of the libsoup HTTP library, widely used by GNOME and other applications for web communication. When processing cookies with specially crafted expiration dates, the library may perform an out-of-bounds memory read. This flaw could result in unintended disclosure of memory contents, potentially exposing sensitive information from the process using libsoup.

Unauthenticated Multiple Vulnerabilities in BitFire Security <= 5.0.3 versions.
CVE-2026-36908 1 Axiomatic 1 Bento4 2026-06-29 5.5 Medium
A stack overflow in the AP4_Array<AP4_TrunAtom::Entry>::EnsureCapacity component of axiomatic-systems Bento4 before v1.8.9allows attackers to cause a Denial of Service (DoS) via a crafted MP4 file.
CVE-2026-36907 1 Axiomatic 1 Bento4 2026-06-29 5.5 Medium
A stack overflow in the AP4_StsdAtom::AP4_StsdAtom component of axiomatic-systems Bento4 before v1.8.9allows attackers to cause a Denial of Service (DoS) via a crafted MP4 file.
CVE-2026-57874 2 Geovision, Geovision Inc. 2 Gv-lpc2011, Gv-lpclpc2011 2211 2026-06-29 7.5 High
An unauthenticated buffer overflow vulnerability exists in IEEE8021x_upload.cgi in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient bounds checking when parsing filename values in multipart upload data. A remote attacker may exploit this vulnerability by sending a crafted upload request with overly long input, causing memory corruption and resulting in a denial of service.
CVE-2026-57879 2 Geovision, Geovision Inc. 2 Gv-lpc2011, Gv-lpclpc2011 2211 2026-06-29 9.8 Critical
An unauthenticated stack-based buffer overflow vulnerability exists in ssvr in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient bounds checking when processing RTSP custom authentication data. A remote attacker may exploit this vulnerability by sending a crafted RTSP request, resulting in memory corruption, denial of service, or potentially arbitrary code execution.
CVE-2026-5757 1 Ollama 1 Ollama 2026-06-29 7.5 High
Unauthenticated remote information disclosure vulnerability in Ollama's model quantization engine allows an attacker to read and exfiltrate the server's heap memory, potentially leading to sensitive data exposure, further compromise, and stealthy persistence.
CVE-2026-48770 1 Notepad-plus-plus 2 Notepad++, Notepad\+\+ 2026-06-29 5 Medium
Notepad++ is a free and open-source source code editor. Prior to 8.9.6.1, a local process in the same interactive Windows session can send a malformed WM_COPYDATA message to Notepad++ using the COPYDATA_FULL_CMDLINE path. The handler appears to process COPYDATASTRUCT.lpData as an unbounded NUL-terminated wchar_t* instead of enforcing COPYDATASTRUCT.cbData. This vulnerability is fixed in 8.9.6.1.
CVE-2026-13587 1 Seladb 1 Pcapplusplus 2026-06-29 3.7 Low
A vulnerability was found in seladb PcapPlusPlus 25.05. The affected element is the function parse_by_block_type of the file light_pcapng.c of the component LightPcapNg Parser. Performing a manipulation of the argument captured_packet_length results in heap-based buffer overflow. It is possible to initiate the attack remotely. The attack's complexity is rated as high. The exploitability is described as difficult. The exploit has been made public and could be used.
CVE-2026-11979 1 Xmlsoft 1 Libxml2 2026-06-29 7.8 High
libxml2 is vulnerable to multiple stack-based buffer overflows in the xmlcatalog utility when running in --shell mode. The usershell() function processes user input using fixed-size stack buffers without proper bounds checking. By supplying an overly long input line, an attacker can overflow internal buffers (command, arg, and argv) during input parsing. This results in memory corruption within the stack frame. Successful exploitation may cause a crash or potentially allow arbitrary code execution in the context of the xmlcatalog process. This issue has been fixed in the commit c2e233fc. NOTE: The maintainers of this project did not agree that this issue is a vulnerability and considered it a bug.
CVE-2026-13588 1 Seladb 1 Pcapplusplus 2026-06-29 5.6 Medium
A vulnerability was determined in seladb PcapPlusPlus 25.05. The impacted element is the function pcpp::SSLClientHelloMessage::getHandshakeVersion of the file Packet++/src/SSLHandshake.cpp of the component TLS Hello Handler. Executing a manipulation of the argument handshakeVersion can lead to heap-based buffer overflow. It is possible to launch the attack remotely. This attack is characterized by high complexity. The exploitability is regarded as difficult. The exploit has been publicly disclosed and may be utilized. This patch is called 98e671010bc7c87b95898c22ae289220ae92542b. It is best practice to apply a patch to resolve this issue.

This affects the function pcpp::TelnetLayer::getSubCommand of the file Packet++/src/TelnetLayer.cpp of the component Telnet Subnegotiation Packet Handler. The manipulation leads to heap-based buffer overflow. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitability is reported as difficult. The exploit is publicly available and might be used. The identifier of the patch is 98e671010bc7c87b95898c22ae289220ae92542b. It is recommended to apply a patch to fix this issue.
CVE-2026-13582 1 Edimax 1 Ew-7478apc 2026-06-29 8.8 High
A flaw has been found in Edimax EW-7478APC 1.04. This issue affects the function formUSBAccount of the file /goform/formUSBAccount of the component POST Request Handler. This manipulation of the argument UserName/Password causes buffer overflow. The attack is possible to be carried out remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-13580 1 Edimax 1 Ew-7478apc 2026-06-29 8.8 High
A security vulnerability has been detected in Edimax EW-7478APC 1.04. This affects the function formQoS of the file /goform/formQoS of the component POST Request Handler. The manipulation of the argument selSSID leads to buffer overflow. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-53303 1 Linux 1 Linux Kernel 2026-06-29 7.1 High
In the Linux kernel, the following vulnerability has been resolved: f2fs: protect extension_list reading with sb_lock in f2fs_sbi_show() In f2fs_sbi_show(), the extension_list, extension_count and hot_ext_count are read without holding sbi->sb_lock. If a concurrent sysfs store modifies the extension list via f2fs_update_extension_list(), the show path may read inconsistent count and array contents, potentially leading to out-of-bounds access or displaying stale data. Fix this by holding sb_lock around the entire extension list read and format operation.
CVE-2026-58058 1 Nmap 1 Nmap 2026-06-29 6.5 Medium
Nmap through 7.99 does not keep the IPv6 extension-header walk within the captured packet in ipv6_get_data_primitive (libnetutil/netutil.cc), so the pointer advances past the buffer and the remaining-length computation underflows to a large value. A scanned target or on-path attacker returning a crafted IPv6 response with a truncated extension header can trigger out-of-bounds reads and a crash during raw IPv6 scans.
CVE-2026-13515 1 Tenda 1 Jd12l 2026-06-29 8.8 High
A security vulnerability has been detected in Tenda JD12L 16.03.53.23. Impacted is the function formSetPPTPServer of the file /goform/SetPptpServerCfg. Such manipulation of the argument startIp leads to stack-based buffer overflow. The attack can be launched remotely. The exploit has been disclosed publicly and may be used.
