| CVE-2026-4480 | 2 Redhat, Samba | 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more | 2026-11-04 | 9 Critical |
| A flaw was found in the Samba printing subsystem. Samba passes the client-controlled job description string to the command configured with the "print command" setting via the "%J" substitution character without escaping shell meta characters. A remote attacker could exploit this vulnerability by sending a specially crafted print job description that contains unescaped shell characters. This could lead to remote code execution on the affected system. | ||||
| CVE-2026-4408 | 2 Redhat, Samba | 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more | 2026-11-04 | 9 Critical |
| A flaw was found in Samba. A remote attacker can exploit a misconfiguration in Samba file servers and classic domain controllers that use the "check password script" feature. If this script is configured with the %u substitution character, the client-controlled username is passed without proper escaping of shell meta-characters. This vulnerability allows an attacker to achieve remote command execution on the affected system. This issue primarily affects non-standard configurations where the "check password script" is used with %u and the samba-dcerpcd service is started as a system service. | ||||
| CVE-2026-19843 | 1 Redhat | 7 Directory Server, Directory Server E2s, Directory Server E4s and 4 more | 2026-11-04 | 8.4 High |
| A flaw was found in 389-ds-base. The Cockpit 389 Console's LDAP editor constructs an ldapsearch command by embedding an LDAP entry's distinguished name (DN) into a shell command string without proper escaping. An LDAP user with delegated privileges to create or rename directory entries could craft a malicious DN containing shell metacharacters. When a Cockpit administrator subsequently views the entry in the 389 Console, the embedded shell command executes with root privileges on the directory server host. | ||||
| CVE-2026-16524 | 1 Redhat | 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more | 2026-11-04 | 7.8 High |
| A command injection flaw in PCP's linux_sockets PMDA allows malicious shell metacharacters via the network.persocket.filter metric. This failed validation lets attackers execute arbitrary commands as the PMDA user when metrics refresh. | ||||
| CVE-2026-16445 | 1 Redhat | 8 Enterprise Linux, Hummingbird, Openshift and 5 more | 2026-11-04 | 7.5 High |
| A flaw was found in dracut. A remote attacker on the adjacent network can exploit this vulnerability by providing specially crafted DHCP options, such as a malicious root-path, next-server, or bootfile name, to a system using dracut's NetworkManager-based initrd network module. These options are improperly handled and written into a temporary shell script without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs during system boot. | ||||
| CVE-2026-101258 | 2 Ghostscript, Redhat | 3 Ghostscript, Enterprise Linux, Rhel Els | 2026-11-04 | 7.8 High |
| A flaw was found in Ghostscript. When Ghostscript renders a crafted PostScript or EPS document, it can bypass the -dSAFER sandbox and execute arbitrary shell commands in the context of the Ghostscript process. The issue chains memory corruption in document parsing with disabling of internal path access controls at runtime. An attacker can deliver the document directly or through formats that delegate rendering to Ghostscript (for example EPS import or print conversion workflows). Successful exploitation can compromise confidentiality, integrity, and availability of data accessible to the process running Ghostscript. | ||||
| CVE-2026-105958 | 2 Red Hat, Redhat | 3 Enterprise Linux, Enterprise Linux, Rhel Els | 2026-11-04 | 7.5 High |
| A flaw was found in spice-server. Multiple migration data handlers use client-supplied offsets from SPICE_MSGC_MIGRATE_DATA messages without bounds validation, allowing a malicious authenticated SPICE client during VM live migration to read arbitrary heap memory or trigger heap corruption via out-of-bounds read and write operations on the message buffer. | ||||
| CVE-2025-26598 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-11-04 | 7.8 High |
| An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice() searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching device ID is found, which can lead to out-of-bounds memory access. | ||||
| CVE-2025-26596 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-11-04 | 7.8 High |
| A heap overflow flaw was found in X.Org and Xwayland. The computation of the length in XkbSizeKeySyms() differs from what is written in XkbWriteKeySyms(), which may lead to a heap-based buffer overflow. | ||||
| CVE-2025-26595 | 3 Redhat, Tigervnc, X.org | 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more | 2026-11-04 | 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-2025-10230 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhel Els | 2026-11-04 | 10 Critical |
| A flaw was found in Samba, in the front-end WINS hook handling: NetBIOS names from registration packets are passed to a shell without proper validation or escaping. Unsanitized NetBIOS name data from WINS registration packets are inserted into a shell command and executed by the Samba Active Directory Domain Controller’s wins hook, allowing an unauthenticated network attacker to achieve remote command execution as the Samba process. | ||||
| CVE-2025-0624 | 1 Redhat | 7 Enterprise Linux, Openshift, Rhel Aus and 4 more | 2026-11-04 | 7.6 High |
| A flaw was found in grub2. During the network boot process, when trying to search for the configuration file, grub copies data from a user controlled environment variable into an internal buffer using the grub_strcpy() function. During this step, it fails to consider the environment variable length when allocating the internal buffer, resulting in an out-of-bounds write. If correctly exploited, this issue may result in remote code execution through the same network segment grub is searching for the boot information, which can be used to by-pass secure boot protections. | ||||
| CVE-2025-1244 | 1 Redhat | 7 Enterprise Linux, Openshift Builds, Rhel Aus and 4 more | 2026-11-04 | 8.8 High |
| A command injection flaw was found in the text editor Emacs. It could allow a remote, unauthenticated attacker to execute arbitrary shell commands on a vulnerable system. Exploitation is possible by tricking users into visiting a specially crafted website or an HTTP URL with a redirect. | ||||
| CVE-2024-4467 | 1 Redhat | 8 Advanced Virtualization, Container Native Virtualization, Enterprise Linux and 5 more | 2026-11-04 | 7.8 High |
| A flaw was found in the QEMU disk image utility (qemu-img) 'info' command. A specially crafted image file containing a `json:{}` value describing block devices in QMP could cause the qemu-img process on the host to consume large amounts of memory or CPU time, leading to denial of service or read/write to an existing external file. | ||||
| CVE-2026-93866 | 1 Watchguard | 1 Fireware Os | 2026-11-04 | N/A |
| An integer overflow vulnerability in the WebSocket connection handling used by WatchGuard Fireware OS's Access Portal allows a remote, unauthenticated attacker to write beyond the bounds of a heap buffer by sending a specially crafted request while the Access Portal feature is enabled. | ||||
| CVE-2026-90442 | 1 Watchguard | 1 Fireware Os | 2026-11-04 | N/A |
| A stack-based buffer overflow vulnerability in the Fireware OS certd process allows an authenticated attacker with access to the Firebox management interface to crash the certificate management service and potentially execute arbitrary code by sending a specially crafted request. | ||||
| CVE-2026-112709 | 1 Watchguard | 1 Fireware Os | 2026-11-04 | N/A |
| A heap-based buffer overflow vulnerability in the Fireware OS authentication service allows an attacker who controls or intercepts traffic to the configured Active Directory server to create a denial of service condition and potentially execute arbitrary code by returning a specially crafted response. | ||||
| CVE-2026-109090 | 1 X.org | 1 Libxi | 2026-11-04 | 7.5 High |
| A malicious X server could cause a heap overflow by injecting a large DEVICE_ENABLE reply when processed by libXi before 1.8.4. | ||||
| CVE-2026-109089 | 1 X.org | 1 Libxi | 2026-11-04 | 7.5 High |
| A buffer overflow when handling DEVICE_RESOLUTION in libXi before 1.8.4 could overflow a heap, triggered by a malicious X server. | ||||
| CVE-2026-107590 | 1 Qt | 3 Qt, Qt5compat, Qtbase | 2026-11-04 | N/A |
| An out-of-bounds write vulnerability in the Qt QTextCodec iconv-based encoding of the Qt 5 Compatibility APIs module (Qt Core in Qt 5 and earlier) impacts Qt. Under certain conditions, encoding text with QTextCodec may write outside an internal buffer. This can cause the application to crash and may affect data integrity. | ||||
