In NTFS-3G versions < 2021.8.22, when a specially crafted unicode string is supplied in an NTFS image a heap buffer overflow can occur and allow for code execution.
CVE-2020-26664 2 Debian, Videolan 2 Debian Linux, Vlc Media Player 2026-07-09 6.8 MEDIUM 7.8 HIGH
A vulnerability in EbmlTypeDispatcher::send in VideoLAN VLC media player 3.0.11 allows attackers to trigger a heap-based buffer overflow via a crafted .mkv file.
CVE-2026-14355 2 Debian, Php 2 Debian Linux, Php 2026-07-08 N/A 5.6 MEDIUM
In PHP versions 8.2.* before 8.2.32, 8.3.* before 8.3.32, 8.4.* before 8.4.23, 8.5.* before 8.5.8, the AES-WRAP-PAD algorithm implementation in OpenSSL extension contains a buffer allocation flaw. The output buffer for the AES key-wrap-with-padding operation is sized from the plaintext length without accounting for RFC 5649 expansion. This may cause OpenSSL to write beyond allocated memory, corrupting heap metadata and triggering application abort.
CVE-2018-10902 4 Canonical, Debian, Linux and 1 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2026-07-07 4.6 MEDIUM 7.8 HIGH
It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation.
CVE-2025-62231 4 Debian, Ibm, Redhat and 1 more 11 Debian Linux, Aix, Vios and 8 more 2026-07-01 N/A 7.3 HIGH
A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash.
CVE-2025-62230 4 Debian, Ibm, Redhat and 1 more 11 Debian Linux, Aix, Vios and 8 more 2026-07-01 N/A 7.3 HIGH
A flaw was discovered in the X.Org X server’s X Keyboard (Xkb) extension when handling client resource cleanup. The software frees certain data structures without properly detaching related resources, leading to a use-after-free condition. This can cause memory corruption or a crash when affected clients disconnect.
CVE-2025-4598 5 Debian, Linux, Oracle and 2 more 6 Debian Linux, Linux Kernel, Linux and 3 more 2026-06-30 N/A 4.7 MEDIUM
A vulnerability was found in systemd-coredump. This flaw allows an attacker to force a SUID process to crash and replace it with a non-SUID binary to access the original's privileged process coredump, allowing the attacker to read sensitive data, such as /etc/shadow content, loaded by the original process. A SUID binary or process has a special type of permission, which allows the process to run with the file owner's permissions, regardless of the user executing the binary. This allows the process to access more restricted data than unprivileged users or processes would be able to. An attacker can leverage this flaw by forcing a SUID process to crash and force the Linux kernel to recycle the process PID before systemd-coredump can analyze the /proc/pid/auxv file. If the attacker wins the race condition, they gain access to the original's SUID process coredump file. They can read sensitive content loaded into memory by the original binary, affecting data confidentiality.
CVE-2025-26466 3 Canonical, Debian, Openbsd 3 Ubuntu Linux, Debian Linux, Openssh 2026-06-30 N/A 5.9 MEDIUM
A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack.
CVE-2025-3891 3 Apache, Debian, Redhat 3 Http Server, Debian Linux, Enterprise Linux 2026-06-29 N/A 7.5 HIGH
A flaw was found in the mod_auth_openidc module for Apache httpd. This flaw allows a remote, unauthenticated attacker to trigger a denial of service by sending an empty POST request when the OIDCPreservePost directive is enabled. The server crashes consistently, affecting availability.
CVE-2025-3155 3 Debian, Gnome, Redhat 21 Debian Linux, Yelp, Codeready Linux Builder and 18 more 2026-06-29 N/A 7.4 HIGH
A flaw was found in Yelp. The Gnome user help application allows the help document to execute arbitrary scripts. This vulnerability allows malicious users to input help documents, which may exfiltrate user files to an external environment.
CVE-2023-46850 3 Debian, Fedoraproject, Openvpn 4 Debian Linux, Fedora, Openvpn and 1 more 2026-06-23 N/A 9.8 CRITICAL
Use after free in OpenVPN version 2.6.0 to 2.6.6 may lead to undefined behavoir, leaking memory buffers or remote execution when sending network buffers to a remote peer.
CVE-2023-6478 4 Debian, Redhat, Tigervnc and 1 more 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-06-23 N/A 7.6 HIGH
A flaw was found in xorg-server. A specially crafted request to RRChangeProviderProperty or RRChangeOutputProperty can trigger an integer overflow which may lead to a disclosure of sensitive information.
CVE-2023-6377 4 Debian, Redhat, Tigervnc and 1 more 6 Debian Linux, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-06-23 N/A 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.
