| CVE-2026-66801 | 1 Redhat | 1 Multicluster Globalhub | 2026-08-10 | 9.9 Critical |
| A flaw was found in multicluster-global-hub. An attacker who compromises a managed hub can leverage its legitimate Kafka client certificate to publish a CloudEvent (a specification for describing event data in a common way) message to the shared `gh-spec` topic. This message can spoof its source as "global-hub" and target other managed hubs. Due to a lack of binding between the Kafka client principal and the CloudEvent envelope, the agent on the targeted hub accepts this spoofed message and applies arbitrary resources. This vulnerability allows for fleet-wide cluster-admin privilege escalation across all managed hubs. | ||||
| CVE-2026-19079 | 1 Redhat | 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more | 2026-08-08 | 4.4 Medium |
| A TOCTOU (Time-of-Check-Time-of-Use) race condition vulnerability was found in the fixfiles script in policycoreutils. When running fixfiles relabel or fixfiles restore, the script used find and chcon commands to locate and relabel unlabeled files under /tmp and other directories. A local attacker could exploit a race window between the file discovery and the label change operation by swapping directory components with symlinks, causing chcon to follow the symlink and modify SELinux labels on arbitrary system files. This could undermine SELinux mandatory access control protections on critical files such as /etc/shadow. | ||||
| CVE-2026-18938 | 1 Redhat | 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more | 2026-08-08 | 6.2 Medium |
| A flaw was found in p11-kit. A local attacker, or one with equivalent access to a reachable RPC channel, could exploit an integer overflow vulnerability. By sending specially crafted messages, the attacker can cause the system to miscalculate memory allocation for nested attributes. This leads to a memory corruption issue, specifically a heap out-of-bounds write, which can crash the p11-kit RPC parsing process, resulting in a Denial of Service (DoS). This vulnerability is only exploitable on 32 bit systems. | ||||
| CVE-2026-61477 | 2 Libvirt, Redhat | 4 Libvirt, Enterprise Linux, Enterprise Linux For Nvidia 26 and 1 more | 2026-08-08 | 2.3 Low |
| An injection vulnerability was found in libvirt's virtual network driver. The network XML parser does not strip newline characters from DNS TXT record value attributes and SRV record domain/target attributes. These values are written verbatim into the dnsmasq configuration file generated by the network driver, allowing a user with permission to define virtual networks to inject arbitrary dnsmasq configuration directives such as dhcp-script, leading to arbitrary command execution as root. | ||||
| CVE-2023-2235 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2026-08-07 | 7.8 High |
| A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve local privilege escalation. The perf_group_detach function did not check the event's siblings' attach_state before calling add_event_to_groups(), but remove_on_exec made it possible to call list_del_event() on before detaching from their group, making it possible to use a dangling pointer causing a use-after-free vulnerability. We recommend upgrading past commit fd0815f632c24878e325821943edccc7fde947a2. | ||||
| CVE-2024-1086 | 5 Debian, Fedoraproject, Linux and 2 more | 35 Debian Linux, Fedora, Linux Kernel and 32 more | 2026-08-07 | 7.8 High |
| A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660. | ||||
| CVE-2022-2196 | 3 Debian, Linux, Redhat | 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more | 2026-08-07 | 5.8 Medium |
| A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or applying the relevant stable backports (v5.4.233, v5.10.170, v5.15.96, v6.1.14). | ||||
| CVE-2025-4374 | 1 Redhat | 1 Quay | 2026-08-07 | 6.5 Medium |
| A flaw was found in Quay. When an organization acts as a proxy cache, and a user or robot pulls an image that hasn't been mirrored yet, they are granted "Admin" permissions on the newly created repository. | ||||
| CVE-2024-9675 | 2 Buildah Project, Redhat | 21 Buildah, Enterprise Linux, Enterprise Linux Eus and 18 more | 2026-08-07 | 7.8 High |
| A vulnerability was found in Buildah. Cache mounts do not properly validate that user-specified paths for the cache are within our cache directory, allowing a `RUN` instruction in a Container file to mount an arbitrary directory from the host (read/write) into the container as long as those files can be accessed by the user running Buildah. | ||||
| CVE-2026-18508 | 2 Gnu, Redhat | 6 Tar, Enterprise Linux, Hardened Images and 3 more | 2026-08-07 | 4.4 Medium |
| A flaw was found in GNU tar. When extracting an archive with the --one-top-level option, hardlink targets are not confined to the designated top-level directory and may resolve relative to the extraction working directory. A crafted archive can create hardlinks that escape the intended boundary and, when combined with a preexisting symbolic link under the working directory, may allow writing outside that boundary during a single extraction. | ||||
| CVE-2026-47300 | 4 Apple, Linux, Microsoft and 1 more | 9 Macos, Linux Kernel, .net and 6 more | 2026-08-07 | 8.8 High |
| Incorrect implementation of authentication algorithm in ASP.NET Core allows an authorized attacker to elevate privileges over a network. | ||||
| CVE-2026-47302 | 4 Apple, Linux, Microsoft and 1 more | 22 Macos, Linux Kernel, .net and 19 more | 2026-08-07 | 7.5 High |
| Allocation of resources without limits or throttling in .NET allows an unauthorized attacker to deny service over a network. | ||||
| CVE-2026-47303 | 4 Apple, Linux, Microsoft and 1 more | 9 Macos, Linux Kernel, .net and 6 more | 2026-08-07 | 8.8 High |
| Authentication bypass by assumed-immutable data in ASP.NET Core allows an authorized attacker to elevate privileges over a network. | ||||
| CVE-2026-42169 | 2 Gimp, Redhat | 2 Gimp, Enterprise Linux | 2026-08-07 | 7.3 High |
| A heap-buffer-overflow vulnerability exists in the APNG (Animated PNG) file loader of GIMP. This flaw occurs when the `fcTL` width exceeds the `IHDR` width, leading to pixel data being written past the end of a heap allocation. Additionally, a heap-based buffer overflow exists in the DDS plug-in due to a BPP mismatch in the `load_layer()` function. Both vulnerabilities can be triggered by opening a specially crafted image file, potentially leading to code execution. | ||||
| CVE-2026-16071 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid 8 and 5 more | 2026-08-07 | 5.4 Medium |
| A flaw was found in the LDAP storage provider of Keycloak, which is used to federate user identities from external directories. The issue occurs when a delegated administrator performs a search using a specific LDAP entry Distinguished Name (DN). Due to missing validation, the system allows lookups for users located outside the configured search boundary, leading to the disclosure of account information from unauthorized parts of the directory and unintended importing of those users into local storage. | ||||
| CVE-2026-16100 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid 8 and 5 more | 2026-08-07 | 6.5 Medium |
| A flaw was found in the user-event metrics recording of Keycloak. When metrics are enabled, the system records raw error messages from failed account operations as Prometheus metric labels. Because these error messages can include user-supplied input like nonexistent client IDs, an authenticated user can create a massive number of unique metric entries, eventually exhausting system memory and causing the service to crash or become unavailable. | ||||
| CVE-2026-16442 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid 8 and 5 more | 2026-08-07 | 7.4 High |
| A flaw was found in the SAML broker component of Keycloak, which is used to manage identity federation and user authentication. The issue occurs because the IdP-initiated Single Sign-On endpoint fails to check if a provider is restricted to account linking only. This allows an attacker with control over a linked upstream identity to bypass login restrictions and gain full access to a local user account. | ||||
| CVE-2026-15572 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2026-08-07 | 8.8 High |
| A flaw was found in Keycloak's Dynamic Client Registration (DCR) security policy management. The "Allowed Protocol Mapper Types" policy, which restricts which types of data mappers a client can use, fails to re-validate the mapper type during a client update if the mapper's configuration remains unchanged. An attacker with client registration privileges can exploit this by first registering an allowed mapper type with a malicious configuration and then swapping it for a restricted, high-privilege mapper type (such as one that hardcodes administrative roles). This allows the attacker to gain full administrative access to the Keycloak realm. | ||||
| CVE-2026-44605 | 1 Redhat | 3 Enterprise Linux, Hardened Images, Hummingbird | 2026-08-07 | 5.5 Medium |
| A flaw was found in the RPM Package Manager (RPM). A local user could be affected by a heap buffer overflow vulnerability when processing a specially crafted NDB database file. This issue arises from an error in how RPM handles certain calculations during file parsing, leading to an incorrect memory allocation. An attacker could leverage this to cause a denial of service, making the system unavailable. | ||||
| CVE-2026-18839 | 2 Popt-devel, Redhat | 6 Popt-static, Enterprise Linux, Hardened Images and 3 more | 2026-08-07 | 2.2 Low |
| An integer underflow was found in the popt library when formatting help text for option tables that exceed the terminal width. A local user who can cause an application to print help under those conditions may cause that application to crash or fail to display help, resulting in a denial of service of the affected application. | ||||
