| CVE-2026-86562 | 1 Redhat | 3 Enterprise Linux, Openshift, Openstack | 2026-11-04 | 7.8 High |
| A flaw was found in DPDK lib/vhost. A TOCTOU double-fetch of control-queue descriptors allows a heap buffer overflow with attacker-controlled content in the VDUSE control-queue handler. | ||||
| CVE-2026-86476 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-04 | 8.4 High |
| A flaw was found in gst-plugins-base. A heap buffer overflow can be triggered when processing video buffers whose attached GstVideoMeta metadata declares plane strides and offsets that exceed the actual backing memory allocation. The metadata is not range-checked during deserialization, and the video frame mapping code does not verify that the declared plane geometry fits within the buffer before allowing consumers to read or write video data. A local attacker who controls the sending side of a GStreamer inter-process IPC pipeline can deliver a crafted buffer carrying fabricated strides, causing the receiving process to read or write beyond heap boundaries. Successful exploitation can cause a denial of service or potentially allow code execution within the affected process. | ||||
| CVE-2026-86344 | 1 Redhat | 4 Directory Server, Enterprise Linux, Redhat Directory Server and 1 more | 2026-11-04 | 7.5 High |
| A flaw was found in 389-ds-base. An unauthenticated remote attacker can send a complete LDAP operation followed by the first bytes of an incomplete LDAPMessage on the same connection, causing the server to hand that connection to a second worker thread before the first worker's result is flushed. The second worker blocks until nsslapd-ioblocktimeout while holding the connection mutex, preventing delivery of the completed operation's result. Repeating this across a small number of connections proportional to the configured worker-thread pool size exhausts the entire pool under default configuration, denying service to all clients (anonymous and authenticated, plaintext and TLS) for as long as the attacker maintains the connections. | ||||
| CVE-2026-85197 | 1 Redhat | 3 Enterprise Linux, Enterprise Linux Eus, Rhel Els | 2026-11-04 | 7.6 High |
| A flaw was found in libsoup. A malicious HTTP/2 server or a Man-in-the-Middle (MITM) attacker can exploit a heap use-after-free vulnerability in the HTTP/2 client implementation. This occurs when a GNOME application uploads a file using HTTP/2, and the server sends a GOAWAY frame while the file body is being read asynchronously. This can lead to memory corruption, potentially resulting in information disclosure or arbitrary code execution. | ||||
| CVE-2026-84268 | 1 Redhat | 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more | 2026-11-04 | 8.8 High |
| A flaw was found in the SFTP backend in gvfs. When mounting a share and reading a file, a malicious SFTP server can cause read_reply() to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the allocated buffer size, causing the operation to write past the intended boundaries. This issue allows a malicious server to corrupt adjacent heap memory in the gvfsd-sftp process, resulting in a denial of service as the process aborts upon detecting the heap corruption or potentially allowing arbitrary code execution. | ||||
| CVE-2026-84042 | 2 Containers, Redhat | 5 Crun, Enterprise Linux, Hardened Images and 2 more | 2026-11-04 | 7.8 High |
| A flaw was found in crun. When crun is built with libkrun and a container is started rootful with passt networking (krun.use_passt), crun can execute attacker-controlled payload from the container image with host root privileges. The issue is a regression in crun 1.29. It affects crun >= 1.29 | ||||
| CVE-2026-81627 | 2 Qemu, Redhat | 9 Qemu, Enterprise Linux, Enterprise Linux For Nvidia 26 and 6 more | 2026-11-04 | 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-2026-81624 | 1 Redhat | 9 Build Of Apache Camel For Spring Boot, Camel Spring Boot, Enterprise Linux and 6 more | 2026-11-04 | 7.5 High |
| Undertow is a flexible performant web server used in JBoss EAP and WildFly. A flaw was found in how Undertow handles WebSocket connections. Specifically, certain configuration limits like message buffer sizes and session timeouts cannot be adjusted and default to being unlimited. This allows a remote attacker to send large amounts of data or maintain connections indefinitely, potentially crashing the server by exhausting its memory or other resources. | ||||
| CVE-2026-80186 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-04 | 7.6 High |
| A stack-based buffer overflow vulnerability exists in BlueZ, the Linux Bluetooth protocol stack. A remote user within Bluetooth radio range can send a specially crafted Extended Inquiry Response (EIR) packet that causes a buffer overflow when the target device performs Bluetooth discovery. This vulnerability can lead to a Denial of Service (DoS) by crashing the bluetoothd service and may allow for arbitrary code execution. | ||||
| CVE-2026-80110 | 1 Redhat | 6 Certificate System, Dogtag Certificate System, Enterprise Linux and 3 more | 2026-11-04 | 8.1 High |
| A flaw was found in pki-core. The v2 REST ACL filter selects a tie-breaking permission for colliding literal and wildcard ACL keys using lexicographic string comparison rather than specificity, causing a wildcard-mapped permission to override a more specific literal-mapped permission when both match. In the CA's profile-management REST API this allows a request to POST /v2/profiles/raw -- intended to require Administrator-level profiles.create permission -- to instead be authorized under the lower-privileged profiles.approve permission held by the default Certificate Manager Agents group. The highest threat from this vulnerability is to confidentiality and integrity of the certificate authority's issuance policy. | ||||
| CVE-2026-79992 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-04 | 7.8 High |
| A flaw was found in Emacs TRAMP. A local attacker could exploit this vulnerability by processing maliciously crafted filenames. This occurs because TRAMP concatenates login arguments without proper sanitization, which are then passed to a local shell. Successful exploitation could lead to arbitrary code execution. | ||||
| CVE-2026-79678 | 1 Redhat | 9 Enterprise Linux, Enterprise Linux Eus, Freeipa and 6 more | 2026-11-04 | 8.1 High |
| A flaw was found in FreeIPA's idp-add command, where insufficiently validated --organization/--base-url input reaches a constrained eval() call before the corresponding LDAP access control check is enforced. This allows any authenticated IPA principal, regardless of privilege level, to enumerate and read the environment variables of the affected server process and to cause denial of service via memory exhaustion. | ||||
| CVE-2026-79655 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-04 | 7.8 High |
| A flaw was found in sos clean, a utility within the sos package. This vulnerability allows a local attacker to perform arbitrary file creation or overwrite. By crafting a malicious tar archive, an attacker can exploit a path traversal issue during tar extraction, where symlink and hardlink targets are not properly validated. This enables the attacker to write files to arbitrary locations on the system with the privileges of the sos clean process, which often runs as root. | ||||
| CVE-2026-78465 | 2 Gimp, Redhat | 3 Gimp, Enterprise Linux, Rhel Els | 2026-11-04 | 7 High |
| A flaw was found in the file-pcx plugin in GIMP, affecting 32-bit builds only. When processing a PCX image file, the plugin calculates memory allocation sizes based on the image dimensions and the number of color planes. If a crafted file sets the number of planes to 4 alongside sufficiently large dimensions, the calculation exceeds the 32-bit integer limit and overflows, resulting in an undersized heap-based buffer allocation. This integer overflow issue results in a heap-based buffer overflow when the plugin subsequently writes image data into the undersized buffer, causing memory corruption, potentially leading to arbitrary code execution or a denial of service. | ||||
| CVE-2026-78409 | 2 Linux, Redhat | 7 Util-linux, Enterprise Linux, Hardened Images and 4 more | 2026-11-04 | 7 High |
| The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to open_tree() with AT_SYMLINK_NOFOLLOW. That flag does not stop intermediate symlink traversal or keep resolution inside the newly mounted filesystem. A local unprivileged user with an fstab-authorized X-mount.subdir entry can attach a host path at the intended mountpoint. | ||||
| CVE-2026-7867 | 1 Redhat | 3 Enterprise Linux, Enterprise Linux Eus, Rhel Els | 2026-11-04 | 7.8 High |
| A flaw was found in udisks2. A local attacker with an active console session can exploit insufficient authorization checking on the 'as-user' option in the org.freedesktop.UDisks2.Filesystem.Mount() D-Bus method. This allows the attacker to spoof the 'as-user' parameter, mounting filesystems on behalf of arbitrary users, including privileged accounts. This can lead to local privilege escalation through mount point injection and manipulation of the mount namespace visible to privileged users. | ||||
