| CVE-2026-97027 | 2 Flatpak, Redhat | 3 Flatpak, Enterprise Linux, Rhel Els | 2026-11-06 | 3.6 Low |
| Flatpak passes through arbitrary vendor-extension keys unmodified when exporting an application's Desktop Entry (.desktop) and D-Bus Service (.service) files, instead of validating against an allowlist. A malicious Flatpak app can use this to cause denial of service (e.g. forced application restart loops) or to influence host D-Bus/systemd activation behavior beyond what the sandbox is intended to permit. | ||||
| CVE-2026-97026 | 2 Flatpak, Redhat | 3 Flatpak, Enterprise Linux, Rhel Els | 2026-11-06 | 3.9 Low |
| Flatpak creates temporary child repository directories under the user cache with world-writable permissions (0777). On multi-user systems with a permissive umask, other local users could read or modify the temporary directory used while installing apps or runtimes, potentially causing installation failures (denial of service); tampered content would fail signature/digest verification rather than being trusted. | ||||
| CVE-2026-97025 | 2 Flatpak, Redhat | 3 Flatpak, Enterprise Linux, Rhel Els | 2026-11-06 | 3.2 Low |
| Flatpak writes the OCI repository authentication token with world-readable permissions (0644) in the system-helper's cache directory, allowing other local users on a multi-user system to read the token and impersonate the authenticated user against the OCI repository. Only OCI-based sources (e.g. as used by Fedora) are affected; libostree-based sources such as Flathub are not. | ||||
| CVE-2026-96546 | 2 Gimp, Redhat | 3 Gimp, Enterprise Linux, Rhel Els | 2026-11-06 | 2.5 Low |
| A one-byte out-of-bounds heap read flaw was found in GIMP's uncompressed DDS image loader. When a user opens an uncompressed DDS image, the file-dds plug-in performs an unconditional one-byte look-ahead after processing the final pixel. This may cause the plug-in to crash if the byte immediately following the pixel buffer is inaccessible; no information disclosure or code execution has been demonstrated. | ||||
| CVE-2026-96284 | 2 Flatpak, Redhat | 3 Flatpak, Enterprise Linux, Rhel Els | 2026-11-06 | 2.5 Low |
| A malicious user can get read-access to files in the flatpak-system-helper context if a system OCI repository is configured, because the OCI code paths in the system helper follow symlinks when importing OCI images that are under the user's control. | ||||
| CVE-2026-96283 | 2 Flatpak, Redhat | 3 Flatpak, Enterprise Linux, Rhel Els | 2026-11-06 | 3.3 Low |
| By calling org.freedesktop.Flatpak.SystemHelper.CancelPull on another user's pull, the pull is not actually cancelled but removed from internal tracking, making it impossible for the owning user to stop it. Ongoing pulls cannot be stopped. | ||||
| CVE-2026-96282 | 2 Flatpak, Redhat | 3 Flatpak, Enterprise Linux, Rhel Els | 2026-11-06 | 3.1 Low |
| A malicious Flatpak extension can probe the host filesystem to determine what files and directories exist at arbitrary paths, and host directory listings can be disclosed to sandboxed applications using the extension. Additionally, unvalidated extension metadata can cause extension content to be mounted at unintended locations inside the sandbox. | ||||
| CVE-2026-93009 | 3 Dnsmasq, Red Hat, Redhat | 9 Dnsmasq, Enterprise Linux, Ceph Storage and 6 more | 2026-11-06 | 4.3 Medium |
| A flaw was found in dnsmasq. The DHCPv6 client hostname parser can read one byte past the end of a crafted FQDN option because it checks the next label length before confirming the pointer is still inside the option. An attacker on the local network can trigger this with a single DHCPv6 packet. The extra byte is not returned to the client or logged, and no crash has been demonstrated. | ||||
| CVE-2026-93010 | 3 Dnsmasq, Red Hat, Redhat | 9 Dnsmasq, Enterprise Linux, Ceph Storage and 6 more | 2026-11-06 | 4.3 Medium |
| A flaw was found in dnsmasq. When DHCP leasequery is enabled without listing allowed source addresses, the server does not check who sent the query. A host on the local network can request DHCP lease records and learn assigned addresses, MAC addresses, hostnames, and related lease metadata. The feature is off unless an administrator turns it on. | ||||
| CVE-2026-91926 | 1 Redhat | 1 Enterprise Linux | 2026-11-06 | 3.7 Low |
| A flaw was found in gss-ntlmssp. A memory leak occurs in the NTLM target-info parser when a crafted NTLM CHALLENGE message contains duplicated string-valued AV_PAIR entries. The parser allocates memory for each string value but does not free the previous allocation when the same AV_PAIR type appears more than once, leaking the earlier allocation. A malicious or man-in-the-middle server can exploit this to cause gradual memory exhaustion on the client during NTLM authentication, leading to a denial of service. | ||||
| CVE-2026-91142 | 1 Redhat | 4 Enterprise Linux, Openshift Dev Spaces, Openshift Devspaces and 1 more | 2026-11-06 | 3.6 Low |
| A flaw was found in Cockpit. An authenticated local user with a large user identifier (UID) can cause unauthorized modification and disclosure of login records. On 32-bit systems, an integer overflow during session accounting allows the user's login process to read or overwrite the legacy log entries of other accounts. | ||||
| CVE-2026-90463 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhel Els | 2026-11-06 | 4 Medium |
| A flaw was found in the sssd NSS responder. This input validation vulnerability allows a local attacker, by sending specially crafted service lookup requests to the NSS responder's UNIX socket, to cause an out-of-bounds read. This out-of-bounds read may lead to a denial of service (DoS) by crashing the NSS responder process. While unprivileged local clients can typically reach the socket, there is no evidence of privilege escalation or reliable data disclosure. | ||||
| CVE-2026-87876 | 2 Openprinting, Redhat | 7 Cups, Enterprise Linux, Hardened Images and 4 more | 2026-11-06 | 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-2026-86564 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-11-06 | 3.3 Low |
| A flaw was found in DPDK lib/vhost. Missing length validation before reading command_data in the virtio-net control-queue handler can cause an out-of-bounds read and a host process crash. | ||||
| CVE-2026-85498 | 2 Polkit Project, Redhat | 5 Polkit, Enterprise Linux, Hummingbird and 2 more | 2026-11-06 | 3.5 Low |
| A flaw was found in polkit. When processing input that begins with a null byte, an arithmetic error in the authentication agent helper causes an integer underflow during buffer length calculation, resulting in an out-of-bounds memory read. An attacker capable of supplying crafted input can trigger this flaw, potentially causing an application crash and resulting in a Denial of Service (DoS). | ||||
| CVE-2026-84823 | 1 Redhat | 5 Enterprise Linux, Jboss Enterprise Application Platform, Jboss Fuse and 2 more | 2026-11-06 | 7.1 High |
| A flaw was found in WildFly. A user with the `Monitor` role, which is the lowest standard Role-Based Access Control (RBAC) role, can exploit a path traversal vulnerability in the `take-snapshot` operation. By manipulating the `name` parameter, this user can write a copy of the server configuration to an arbitrary location. This allows the `Monitor` role to read back the server configuration, including sensitive credentials, which would otherwise be restricted by RBAC, leading to information disclosure. | ||||
| CVE-2026-97175 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-11-06 | 8.8 High |
| A flaw was found in the idp-auto-link authenticator of the keycloak-services component, which handles user identity federation. The issue occurs when Keycloak automatically links an incoming identity from an external provider to an existing local account based on an email address without verifying if the provider has validated that email. This can allow an attacker to take over a victim's account by using a matching unverified email address at a brokered provider. | ||||
| CVE-2026-79699 | 1 Redhat | 7 Ansible Automation Platform, Container Native Virtualization, Enterprise Linux and 4 more | 2026-11-06 | 4.4 Medium |
| A flaw was found in the containers/storage library. A crafted tar archive containing a malicious whiteout header (e.g. victim/.wh.) can cause the extraction destination directory to be replaced with an arbitrary file when processed by storage/pkg/archive.UnpackLayer, ApplyLayer, or ApplyUncompressedLayer. | ||||
| CVE-2026-68744 | 3 Fedoraproject, Redhat, Sssd | 6 Sssd, Enterprise Linux, Openshift and 3 more | 2026-11-06 | 3.3 Low |
| A flaw was found in SSSD. The sss_nss_protocol_fill_initgr() function in the NSS responder pre-allocates reply space for all group entries but does not shrink the packet when groups are skipped, causing uninitialized heap bytes to be transmitted to the client. A local attacker can exploit this to disclose cached directory data and heap layout information from the sssd_nss process. | ||||
| CVE-2026-6842 | 1 Redhat | 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more | 2026-11-06 | 2.5 Low |
| A flaw was found in nano. In environments with permissive umask settings, a local attacker can exploit incorrect directory permissions (0777 instead of 0700) for the `~/.local` directory. This allows the attacker to inject a malicious `.desktop` launcher, which could lead to unintended actions or information disclosure if the launcher is subsequently processed. | ||||
