| 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. | ||||
| CVE-2026-76578 | 1 Redhat | 9 Enterprise Linux, Enterprise Linux Eus, Freeipa and 6 more | 2026-11-04 | 9.8 Critical |
| A flaw was found in FreeIPA. The self-managed OTP token ACI does not require authentication and does not restrict which attributes may be added alongside the token entry. An unauthenticated LDAP client can exploit this, combined with a related flaw in the underlying directory server's ACI evaluation (tracked separately), to create an arbitrary attacker-controlled Kerberos principal and have it added to the administrators group. This allows a remote, unauthenticated attacker to obtain genuine FreeIPA administrator-group membership and perform administrative operations against the directory and, on SID-enabled deployments, other IdM services. | ||||
| CVE-2026-76561 | 1 Redhat | 9 Certificate System, Enterprise Linux, Enterprise Linux Eus and 6 more | 2026-11-04 | 7.2 High |
| A flaw was found in Dogtag PKI, as used by FreeIPA's certificate authority component. The certificate profile import functionality does not fully validate uploaded profile content beyond the profile ID. An authenticated user with CA Administrator privileges can exploit Dogtag's ExternalProcessConstraint mechanism to execute arbitrary commands with attacker-controlled environment variables, achieving code execution as the pkiuser account. | ||||
| CVE-2026-76560 | 1 Redhat | 10 Directory Server, Directory Server E4s, Enterprise Linux and 7 more | 2026-11-04 | 7.5 High |
| A flaw was found in 389 Directory Server. The SELFDN ACI bind-rule evaluator incorrectly matches an anonymous LDAP client's empty bind DN against an empty stored attribute value, allowing an unauthenticated client to satisfy access control checks intended to require a matching authenticated identity. This can allow an anonymous LDAP client to perform an operation, such as adding or modifying a directory entry, that a SELFDN-based ACI intended to restrict to a specific authenticated user. | ||||
| CVE-2026-75092 | 1 Redhat | 3 Enterprise Linux, Openstack, Rhel Eus | 2026-11-04 | 7.3 High |
| A privilege escalation flaw was found in the scan_mysql actor of leapp-upgrade-el9toel10 (provided by leapp-repository). During RHEL 9 to RHEL 10 upgrades, the actor runs: mysqld --validate-config --log-error-verbosity=2 directly as root in the Leapp actor context, bypassing the packaged MySQL systemd unit that normally starts the daemon as User=mysql. A process compromised as the mysql OS identity can write a version-2 persisted configuration (mysqld-auto.cnf) and a malicious shared object into /var/lib/mysql (a directory owned by mysql). That persisted map can set plugin_dir to /var/lib/mysql and early_plugin_load (or related loader options such as plugin_load / plugin_load_add) so MySQL loads the attacker-controlled object during configuration validation. Plugin loading can reach dlopen() before MySQL’s runtime-user check and before plugin-symbol validation. When an administrator subsequently runs the documented Leapp preupgrade or upgrade workflow, attacker-controlled code can execute as UID 0 with a full capability set in an unconfined SELinux domain (unconfined_t). The attack does not require write access to the default system plugin path under /usr; redirecting plugin_dir via mysql-owned persisted state is sufficient. Ordinary SQL privileges alone (including highly privileged SQL accounts) are not a sufficient startpoint — OS-level execution as the mysql service identity is required, plus later administrator invocation of Leapp. | ||||
| CVE-2026-71217 | 2 Iperf3 Project, Redhat | 3 Iperf3, Enterprise Linux, Rhel Els | 2026-11-04 | 7.5 High |
| A flaw was found in iperf3. A remote attacker can exploit this vulnerability by sending crafted control-channel JSON with oversized numeric parameters, such as `parallel` and `len`, which are not properly validated by the server. This improper input validation can lead to excessive stream and thread creation, as well as large buffer allocations, causing resource exhaustion. Consequently, this can result in a Denial of Service (DoS) on the affected iperf3 server. | ||||
| CVE-2026-6846 | 3 Gnu, Iputils, Redhat | 8 Binutils, Iputils, Enterprise Linux and 5 more | 2026-11-04 | 7.8 High |
| A flaw was found in binutils. A heap-buffer-overflow vulnerability exists when processing a specially crafted XCOFF (Extended Common Object File Format) object file during linking. A local attacker could trick a user into processing this malicious file, which could lead to arbitrary code execution, allowing the attacker to run unauthorized commands, or cause a denial of service, making the system unavailable. | ||||
| CVE-2026-56211 | 2 Aomedia, Redhat | 7 Libaom, Ai Inference Server, Enterprise Linux and 4 more | 2026-11-04 | 7.1 High |
| A remote code execution vulnerability was found in libaom, the reference AV1 codec implementation. Insufficient bounds validation in the AV1 encoder's SVC (Scalable Video Coding) layer ID control allows an attacker to supply crafted video frame pixels that overlap with internal encoder layer context structures. In fork-based video processing services, an attacker can use this to hijack the cyclic refresh map pointer, brute-force the process base address via a crash oracle, and redirect control flow to achieve arbitrary command execution. Exploitation requires the target service to use libaom with SVC encoding enabled and accept attacker-supplied video frames. | ||||
| CVE-2026-44344 | 1 Chamilo | 1 Chamilo Lms | 2026-11-04 | 6.6 Medium |
| Chamilo LMS is an open-source learning management system. In the 1.x line before 1.11.40, and the 2.x line before 2.0.1, multiple `eval()` calls in the vendored PEAR `HTML_QuickForm` libraries can execute arbitrary PHP code if form element names contain attacker-influenced data. Standard Chamilo forms use hardcoded element names; exploitation requires a developer-specific plugin or misconfiguration that lets user input reach those element names. Where that conditional path exists, the impact can be full server compromise. This issue is fixed in versions 1.11.40 and 2.0.1. | ||||
| CVE-2026-73198 | 2 Freeipa, Redhat | 9 Freeipa, Enterprise Linux, Enterprise Linux Eus and 6 more | 2026-11-04 | 7.5 High |
| A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the `/ipa/i18n_messages` endpoint by sending an arbitrarily large request body. This can cause the service to consume excessive memory, leading to memory exhaustion, degraded responsiveness, and a denial of service (DoS) condition. | ||||
| CVE-2026-73197 | 2 Freeipa, Redhat | 9 Freeipa, Enterprise Linux, Enterprise Linux Eus and 6 more | 2026-11-04 | 7.5 High |
| A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by sending oversized form POST requests to the `/ipa/migration/migration.py` endpoint. This can force the migration handler to read attacker-controlled request bodies fully into memory, leading to increased memory usage, slower request handling, and potential service disruption or denial of service. | ||||
| CVE-2026-72694 | 2 Mrtgconfig, Redhat | 9 Mrtg, Enterprise Linux, Enterprise Linux Eus and 6 more | 2026-11-04 | 7.1 High |
| A flaw was found in MRTG. When the MRTG daemon is started as a root user and subsequently drops privileges, a local, low-privileged attacker can exploit a symbolic link (symlink) following vulnerability. By influencing or pre-placing a symlink in the process ID (PID) file path, the attacker can trick the root process into changing the ownership of an arbitrary existing file to the daemon user. This can lead to local privilege escalation, allowing unauthorized access to or modification of sensitive files. | ||||
| CVE-2026-118263 | 1 Labstack | 1 Echo | 2026-11-04 | 5.3 Medium |
| Echo is a Go web framework. From 5.0.0 until 5.4.1, Echo v5's BodyDump middleware can discard a BodyLimit overflow error for an unknown-length request when BodyDump's capture limit is below the BodyLimit threshold. BodyDump drains the remaining body while ignoring read errors and replaces it with the captured prefix, so an HTTP/1.1 chunked request can be truncated and processed successfully even though the original body exceeded the configured limit. Known-length requests rejected before BodyDump runs are unaffected, and the issue does not establish a general authentication bypass or denial of service. This issue is fixed in 5.4.1. | ||||
| CVE-2026-118264 | 1 Labstack | 1 Echo | 2026-11-04 | 7.4 High |
| Echo is a Go web framework. From 4.0.0 until 4.16.1 and 5.4.1, Echo's Proxy middleware selects a raw tunnel from a client WebSocket upgrade request before verifying that the configured upstream accepted the upgrade. If the upstream rejects the upgrade with an ordinary keep-alive response, later HTTP requests on the connection are sent directly to that upstream without passing through Echo's router or route-specific middleware. This can bypass authentication or authorization enforced only by Echo routes, but requires an accessible proxy route, a cooperating rejected-upgrade response, and a target without independent upstream authorization. This issue is fixed in 4.16.1 and 5.4.1. | ||||
| CVE-2026-118260 | 1 Labstack | 1 Echo | 2026-11-04 | 7.5 High |
| Echo is a Go web framework. From 4.0.0 until 4.16.1, Echo v4's opt-in BodyDump middleware reads complete request bodies into memory before handlers run and retains complete response bodies for the dump callback without capture limits. An unauthenticated client that can reach a route using BodyDump can submit large bodies or influence large responses, causing repeated or concurrent allocations that exhaust process memory. BodyDump is not enabled by default, and external request limits may reduce request-side exposure but do not bound response capture. This issue is fixed in 4.16.1. | ||||
| CVE-2026-111932 | 1 Coder | 1 Coder | 2026-11-04 | 3.4 Low |
| Coder before 2.29.17, 2.30.0 before 2.32.7, 2.33.0 before 2.33.8, and 2.34.0 before 2.34.2 contains a stored HTML injection vulnerability because the ApplicationName and LogoURL appearance settings are rendered into HTML output without sufficient escaping. Attackers with the Owner role can store HTML markup in these settings that renders in the Coder dashboard and in SMTP notification emails sent to other deployment users. | ||||
| CVE-2025-64064 | 1 Primakon | 2 Pi Portal, Project Contract Management | 2026-11-04 | 8.8 High |
| Primakon Pi Portal 1.0.18 /api/v2/pp_users endpoint fails to adequately check user permissions before processing a PATCH request to modify the PP_SECURITY_PROFILE_ID. Because of weak access controls any low level user can use this API and change their permission to Administrator by using PP_SECURITY_PROFILE_ID=2 inside body of request and escalate privileges. | ||||
| CVE-2026-118265 | 1 Labstack | 1 Echo | 2026-11-04 | 5.3 Medium |
| Echo is a Go web framework. From 5.0.0 until 5.4.1, Echo v5's ExtractIPFromRealIPHeader validates whether the client-supplied X-Real-IP value belongs to a trusted range instead of validating the direct network peer. A client reaching Echo directly, or through a proxy that preserves the header, can supply a loopback or private address and have Context.RealIP return that spoofed identity. Applications using the extractor for IP allowlists, rate limiting, audit logs, or forwarding headers can consequently trust an attacker-controlled address; the default direct extractor and Echo v4 are unaffected. This issue is fixed in 5.4.1. | ||||
| CVE-2026-116776 | 1 N-romanovich | 1 Usb-test | 2026-11-04 | N/A |
| USB Test is a lightweight Windows CLI utility for verifying sector integrity and detecting overreported capacity on USB flash drives. Prior to version 1.1.5, getSectorSize() in USB Test/src/driveinfo.cpp trusts DISK_GEOMETRY.BytesPerSector returned by IOCTL_DISK_GET_DRIVE_GEOMETRY without checking whether the call succeeded or enforcing size bounds. USB Test/src/drivetest.cpp uses the value for division and to size a heap buffer before memcpy(buffer.data(), §or, 8), so a physically connected malicious USB storage device can report a value below eight bytes and cause repeated out-of-bounds writes, or report zero and cause a divide-by-zero denial of service when a user starts a drive test. The heap corruption can crash the elevated application and may permit arbitrary code execution. This issue is fixed in version 1.1.5. | ||||
