CVE-2024-9355 1 Redhat 26 Amq Streams, Ansible Automation Platform, Container Native Virtualization and 23 more 2026-09-21 6.5 Medium
A vulnerability was found in Golang FIPS OpenSSL. This flaw allows a malicious user to randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode. It may also be possible to force a false positive match between non-equal hashes when comparing a trusted computed hmac sum to an untrusted input sum if an attacker can send a zeroed buffer in place of a pre-computed sum.  It is also possible to force a derived key to be all zeros instead of an unpredictable value.  This may have follow-on implications for the Go TLS stack.
CVE-2026-81665 2 Corosync, Redhat 10 Corosync, Enterprise Linux, Enterprise Linux Eus and 7 more 2026-09-21 7.5 High
A heap-based buffer overflow was found in Corosync's Totem Process Group (totempg) message reassembly. When processing fragmented multicast messages, the buffer used to reassemble fragments lacks a runtime bounds check in release builds. A network-adjacent attacker able to send crafted multicast protocol messages to the cluster could cause a heap buffer overflow with attacker-controlled data. This can crash the Corosync daemon, causing a denial of service to the entire cluster, and may potentially allow further exploitation given sufficient heap-corruption control.
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-2026-54231 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-2026-16445 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-2025-6021 2 Redhat, Xmlsoft 30 Discovery, Enterprise Linux, Enterprise Linux Eus and 27 more 2026-09-18 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-2023-40283 4 Canonical, Debian, Linux and 1 more 9 Ubuntu Linux, Debian Linux, Linux Kernel and 6 more 2026-09-18 7.8 High
An issue was discovered in l2cap_sock_release in net/bluetooth/l2cap_sock.c in the Linux kernel before 6.4.10. There is a use-after-free because the children of an sk are mishandled.
CVE-2023-1390 2 Linux, Redhat 5 Linux Kernel, Enterprise Linux, Rhel Aus and 2 more 2026-09-18 7.5 High
A remote denial of service vulnerability was found in the Linux kernel’s TIPC kernel module. The while loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue. Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system to instantly spike to 100%, causing a denial of service condition.
CVE-2023-35788 5 Canonical, Debian, Linux and 2 more 20 Ubuntu Linux, Debian Linux, Linux Kernel and 17 more 2026-09-18 7.8 High
An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7. It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets. This may result in denial of service or privilege escalation.
CVE-2026-19387 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more 2026-09-18 7.6 High
A heap out-of-bounds write vulnerability was found in the GStreamer gst-plugins-bad adpcmdec element when decoding IMA/DVI ADPCM audio. Insufficient validation of the per-block sample count for multi-channel streams allows a crafted WAV file to cause writes beyond the allocated output buffer. This can lead to application crash, denial of service, memory corruption, or potentially arbitrary code execution when untrusted media is processed.
CVE-2023-4622 3 Debian, Linux, Redhat 9 Debian Linux, Linux Kernel, Enterprise Linux and 6 more 2026-09-17 7.8 High
A use-after-free vulnerability in the Linux kernel's af_unix component can be exploited to achieve local privilege escalation. The unix_stream_sendpage() function tries to add data to the last skb in the peer's recv queue without locking the queue. Thus there is a race where unix_stream_sendpage() could access an skb locklessly that is being released by garbage collection, resulting in use-after-free. We recommend upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c (or backported equivalents).
CVE-2026-4408 2 Redhat, Samba 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more 2026-09-17 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-2026-1933 2 Redhat, Samba 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-09-17 7.1 High
A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-only exports. This could allow modification of SMB-visible file behavior, including converting files into symbolic links or other reparse point types.
CVE-2026-59691 2 Gstreamer, Redhat 9 Gstreamer, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-09-10 7.1 High
A heap buffer overflow vulnerability was found in GStreamer's rfbsrc plugin. When a client connects to a malicious RFB/VNC server that advertises a 16bpp framebuffer and sends Hextile-encoded updates, the Hextile background fill path writes 32-bit pixel values into a buffer allocated for 16-bit pixels. This type mismatch causes an out-of-bounds heap write that can lead to denial of service (process crash) and potential memory corruption.
CVE-2026-59692 2 Gstreamer, Redhat 9 Gstreamer, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-09-10 7.5 High
A stack buffer overflow vulnerability was found in GStreamer's DTLS plugin. During a DTLS handshake, the peer certificate Subject Distinguished Name is printed into a fixed-size 2048-byte stack buffer without bounds checking. A remote unauthenticated attacker can send a certificate with an oversized Subject DN that exceeds the buffer, causing a stack buffer overflow and process crash, resulting in denial of service.
