| CVE-2026-12912 | 2 Libtiff, Redhat | 11 Libtiff, Enterprise Linux, Enterprise Linux Eus and 8 more | 2026-09-21 | 7.3 High |
| A flaw was found in libtiff. A remote attacker could exploit this vulnerability by providing a specially crafted PixarLog-compressed TIFF image. This issue occurs when decoding Pixarlog codec images with the PIXARLOGDATAFMT_8BITABGR output format and a specific stride value, leading to a heap-based buffer overflow. This could potentially result in arbitrary code execution or a denial of service (DoS). | ||||
| CVE-2026-87876 | 2 Openprinting, Redhat | 6 Cups, Enterprise Linux, Hardened Images and 3 more | 2026-09-21 | 3 Low |
| Two case-insensitive comparisons on request-derived usernames outside the main authorization path in CUPS's scheduler (printer ACL validation and private-attribute filtering) could allow bypass of username-based access controls in certain configurations. | ||||
| CVE-2026-16118 | 1 Redhat | 2 Enterprise Linux, Rhui | 2026-09-21 | 7.1 High |
| A flaw was found in xdgmime. A heap-based buffer overflow can be triggered in _xdg_mime_magic_parse_magic_line() in the xdgmimemagic.c file on little-endian systems when an attacker-controlled MIME magic file in a user-writable XDG data location (e.g., in the $XDG_DATA_HOME/mime/magic path) is parsed by an application performing MIME type detection (e.g., via g_content_type_guess()). When performing byte-swap, incorrect pointer arithmetic on the write side causes an out-of-bounds write of 2 bytes, resulting in an application crash or memory corruption. | ||||
| CVE-2026-85013 | 1 Redhat | 2 Enterprise Linux, Hummingbird | 2026-09-21 | 7.3 High |
| A flaw was found in environment-modules. A local attacker can exploit this vulnerability by placing a maliciously named modulefile in a location visible to the victim's `MODULEPATH`. When the victim uses Bash completion for `module` or `ml` commands, the malicious module name, containing shell metacharacters, is evaluated as a command. This can lead to arbitrary command execution in the completing user's shell, impacting their confidentiality, integrity, and availability. | ||||
| CVE-2026-43961 | 2 Redhat, Vim | 5 Enterprise Linux, Hummingbird, Openshift and 2 more | 2026-09-21 | 7.8 High |
| A flaw was found in Vim's netrw plugin. A crafted filename containing quote characters and expression fragments can break out of the quoted context during mark/unmark operations, allowing arbitrary Vimscript execution. This can be leveraged to run shell commands with the privileges of the user running Vim. | ||||
| CVE-2026-81627 | 2 Qemu, Redhat | 8 Qemu, Enterprise Linux, Enterprise Linux For Nvidia 26 and 5 more | 2026-09-21 | 8.2 High |
| A flaw was found in QEMU. The VAPIC setup hypercall in hw/i386/vapic.c does not validate that the writable RAM alias remains within the option ROM window. A privileged guest user on a Q35/KVM machine can position this alias over locked SMRAM, bypassing chipset D_LCK protection and injecting code into System Management Mode memory. | ||||
| CVE-2026-42784 | 3 Red Hat, Redhat, Sequoia-pgp | 12 Enterprise Linux, Ansible Automation Platform, Confidential Compute Attestation and 9 more | 2026-09-21 | 7.4 High |
| A flaw was found in sequoia-openpgp. The library incorrectly infers key flags for older certificates when a key flags subpacket is missing, leading to a discrepancy in how key capabilities are viewed. This key flag confusion allows an attacker to bypass the back-signature check. Consequently, an attacker can illegitimately bind an arbitrary subkey to their own certificate and forge signatures, completely compromising cryptographic integrity. | ||||
| CVE-2026-73434 | 2 Gstreamer, Redhat | 6 Gstreamer, Enterprise Linux, Enterprise Linux Eus and 3 more | 2026-09-21 | 6.1 Medium |
| A flaw was found in GStreamer gst-plugins-good (avidemux). In gst_avi_demux_riff_parse_vprp(), the number of available gst_riff_vprp_video_field_desc entries is calculated by dividing the remaining buffer size by the attacker-controlled vprp->fields value, rather than by sizeof(gst_riff_vprp_video_field_desc). This can cause the parser to treat more field descriptors as available than fit in the input buffer, resulting in out-of-bounds reads. Processing a crafted AVI via playbin/decodebin can crash the application (denial of service). Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072). | ||||
| CVE-2026-73433 | 2 Gstreamer, Redhat | 6 Gstreamer, Enterprise Linux, Enterprise Linux Eus and 3 more | 2026-09-21 | 6.6 Medium |
| A flaw was found in GStreamer gst-plugins-good (avidemux). When parsing FUJIFILM metadata in an AVI strd chunk, gst_avi_demux_parse_strd() decrements a remaining-length counter by fixed offsets (98 and 10 bytes) without verifying sufficient data remains. For crafted strd payloads of exactly 106 or 107 bytes, the counter underflows to a very large unsigned value, causing subsequent null-terminated string scanning to read far beyond the allocated heap buffer. Date-format normalization may also write beyond the buffer end. Confirmed impacts include heap out-of-bounds read, out-of-bounds write, heap information disclosure (adjacent data appearing in parsed metadata), and application crash/denial of service. The avidemux element is auto-plugged by playbin, decodebin, and gst-discoverer, so opening or previewing a crafted AVI is sufficient to trigger the issue. Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072). | ||||
| CVE-2026-18649 | 1 Redhat | 5 Enterprise Linux, Enterprise Linux Eus, Rhel E4s and 2 more | 2026-09-21 | 7.5 High |
| A flaw was found in the GStreamer gst-plugins-good package. The rtph264depay and rtph265depay RTP depayloader elements do not enforce a maximum size limit on the reassembly buffer used during fragmented RTP packet processing. A remote, unauthenticated attacker can send a continuous stream of RTP fragments without ever transmitting an end-of-fragment marker, causing the reassembly buffer to grow without bound until process memory is exhausted. This results in a denial of service through process termination. | ||||
| CVE-2026-54231 | 2 Fedoraproject, Redhat | 7 Fedora, Automatic Bug Reporting Tool, Enterprise Linux and 4 more | 2026-09-21 | 5.5 Medium |
| A content injection vulnerability was found in the ABRT post-create event handler scripts in libreport. The event script queries the systemd journal for log entries matching the crashed process and writes the results to files in the dump directory without sanitizing embedded control characters. A local user can inject arbitrary content into the journal output by embedding newline characters in syslog messages, controlling the content that root writes to dump directory files. | ||||
| CVE-2025-11234 | 1 Redhat | 7 Enterprise Linux, Openshift, Rhel Aus and 4 more | 2026-09-21 | 7.5 High |
| A flaw was found in QEMU. If the QIOChannelWebsock object is freed while it is waiting to complete a handshake, a GSource is leaked. This can lead to the callback firing later on and triggering a use-after-free in the use of the channel. This can be abused by a malicious client with network access to the VNC WebSocket port to cause a denial of service during the WebSocket handshake prior to the VNC client authentication. | ||||
| CVE-2024-8176 | 1 Redhat | 9 Devworkspace, Discovery, Enterprise Linux and 6 more | 2026-09-21 | 7.5 High |
| A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the environment and library usage. | ||||
| CVE-2026-54230 | 2 Fedoraproject, Redhat | 8 Fedora, Automatic Bug Reporting Tool, Enterprise Linux and 5 more | 2026-09-21 | 7 High |
| A symlink following vulnerability was found in the ABRT post-create event handler scripts in libreport. Event scripts write output files using shell redirections without the O_NOFOLLOW flag. If the target file is replaced with a symlink, the shell process running as root follows the symlink and writes content to the symlink target, allowing arbitrary file overwrites on the system. | ||||
| CVE-2026-63622 | 2 Libvirt, Redhat | 11 Libvirt, Enterprise Linux, Enterprise Linux Eus and 8 more | 2026-09-21 | 7.8 High |
| A flaw was found in libvirt. A local attacker, specifically a process running as the confined `swtpm` user, could exploit a symlink-following vulnerability in the `virFileChownFiles()` function. By planting a symbolic link within the `swtpm` state directory, the attacker could trick the root-level libvirt daemon into changing the ownership of an arbitrary file to the `swtpm` user. This allows for privilege escalation from the `swtpm` sandbox to root-level file ownership control. | ||||
| CVE-2026-18917 | 1 Redhat | 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux Nvidia and 7 more | 2026-09-21 | 7.8 High |
| A flaw was found in libvirt. An unprivileged local user could exploit an integer overflow vulnerability in the NodeGetFreePages RPC handler. This flaw allows crafted values to bypass a size check, leading to an undersized memory buffer. Subsequently, real NUMA node data can overwrite this buffer. This heap buffer overflow can corrupt the root libvirt daemon's memory, potentially leading to a denial of service or local privilege escalation. | ||||
| CVE-2026-16313 | 1 Redhat | 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more | 2026-09-21 | 7.6 High |
| A flaw was found in sg3_utils. The sg_inq command, when invoked with the --export option, outputs device identification data without sanitizing control characters in SCSI name string fields. A newline character embedded in a device-supplied name string can inject arbitrary properties into the udev device database. This could allow an attacker who can present a crafted SCSI device to execute arbitrary commands as root when the device is disconnected. | ||||
| CVE-2026-16445 | 1 Redhat | 7 Enterprise Linux, Hummingbird, Openshift and 4 more | 2026-09-21 | 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-2026-15816 | 1 Redhat | 12 Enterprise Linux, Enterprise Linux Eus, Hardened Images and 9 more | 2026-09-21 | 7.5 High |
| A flaw was found in dracut. The die() error-handling function writes its message into a shell script under the initramfs emergency-hook directory without properly shell-quoting it. When the message contains data derived from the DHCP ROOT_PATH option, an attacker on the adjacent network who controls a rogue DHCP server can inject a command-substitution sequence that executes as root the next time dracut sources its emergency hook scripts during standard boot-failure handling. | ||||
| CVE-2026-6893 | 1 Redhat | 13 Dracut, Enterprise Linux, Enterprise Linux Eus and 10 more | 2026-09-21 | 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 (Dynamic Host Configuration Protocol) options, such as a malicious hostname, to a system using dracut's legacy DHCP path. These options are improperly handled and written into temporary shell scripts without proper escaping, leading to command injection. This allows the attacker to achieve root code execution within the initramfs, potentially compromising the system's boot and network behavior. | ||||
