Additional race conditions in plugin thread lifecycle can cause crashes during connection teardown or shutdown. | |||||
| CVE-2023-52355 | 2 Libtiff, Redhat | 2 Libtiff, Enterprise Linux | 2026-07-22 | N/A | 7.5 HIGH |
| An out-of-memory flaw was found in libtiff that could be triggered by passing a crafted tiff file to the TIFFRasterScanlineSize64() API. This flaw allows a remote attacker to cause a denial of service via a crafted input with a size smaller than 379 KB. | |||||
| CVE-2026-3833 | 2 Gnu, Redhat | 4 Gnutls, Enterprise Linux, Hardened Images and 1 more | 2026-07-22 | N/A | 6.5 MEDIUM |
| A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure. | |||||
| CVE-2026-53009 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-07-22 | N/A | 7.8 HIGH |
| In the Linux kernel, the following vulnerability has been resolved: ice: fix double-free of tx_buf skb If ice_tso() or ice_tx_csum() fail, the error path in ice_xmit_frame_ring() frees the skb, but the 'first' tx_buf still points to it and is marked as valid (ICE_TX_BUF_SKB). 'next_to_use' remains unchanged, so the potential problem will likely fix itself when the next packet is transmitted and the tx_buf gets overwritten. But if there is no next packet and the interface is brought down instead, ice_clean_tx_ring() -> ice_unmap_and_free_tx_buf() will find the tx_buf and free the skb for the second time. The fix is to reset the tx_buf type to ICE_TX_BUF_EMPTY in the error path, so that ice_unmap_and_free_tx_buf(). Move the initialization of 'first' up, to ensure it's already valid in case we hit the linearization error path. The bug was spotted by AI while I had it looking for something else. It also proposed an initial version of the patch. I reproduced the bug and tested the fix by adding code to inject failures, on a build with KASAN. I looked for similar bugs in related Intel drivers and did not find any. | |||||
| CVE-2026-10533 | 1 Redhat | 1 Openshift Container Platform | 2026-07-22 | N/A | 5.0 MEDIUM |
| A flaw was found in OpenShift Container Platform. Completed pods with restartPolicy: Never do not count toward ResourceQuota pod limits, and Kubernetes events are not quota-scoped. A non-privileged user who can create pods in a namespace can exploit this to generate a large volume of events that accumulate in etcd, causing API server performance degradation across the cluster. | |||||
| CVE-2026-28369 | 1 Redhat | 10 Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot, Data Grid and 7 more | 2026-07-22 | N/A | 8.7 HIGH |
| A flaw was found in Undertow. When Undertow receives an HTTP request where the first header line starts with one or more spaces, it incorrectly processes the request by stripping these leading spaces. This behavior, which violates HTTP standards, can be exploited by a remote attacker to perform request smuggling. Request smuggling allows an attacker to bypass security mechanisms, access restricted information, or manipulate web caches, potentially leading to unauthorized actions or data exposure. | |||||
| CVE-2024-0639 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-07-21 | N/A | 5.5 MEDIUM |
| A denial of service vulnerability due to a deadlock was found in sctp_auto_asconf_init in net/sctp/socket.c in the Linux kernel’s SCTP subsystem. This flaw allows guests with local user privileges to trigger a deadlock and potentially crash the system. | |||||
| CVE-2024-0443 | 3 Fedoraproject, Linux, Redhat | 3 Fedora, Linux Kernel, Enterprise Linux | 2026-07-21 | N/A | 5.5 MEDIUM |
| A flaw was found in the blkgs destruction path in block/blk-cgroup.c in the Linux kernel, leading to a cgroup blkio memory leakage problem. When a cgroup is being destroyed, cgroup_rstat_flush() is only called at css_release_work_fn(), which is called when the blkcg reference count reaches 0. This circular dependency will prevent blkcg and some blkgs from being freed after they are made offline. This issue may allow an attacker with a local access to cause system instability, such as an out of memory error. | |||||
| CVE-2023-3640 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-07-21 | N/A | 7.0 HIGH |
| A possible unauthorized memory access flaw was found in the Linux kernel's cpu_entry_area mapping of X86 CPU data to memory, where a user may guess the location of exception stacks or other important data. Based on the previous CVE-2023-0597, the 'Randomize per-cpu entry area' feature was implemented in /arch/x86/mm/cpu_entry_area.c, which works through the init_cea_offsets() function when KASLR is enabled. However, despite this feature, there is still a risk of per-cpu entry area leaks. This issue could allow a local user to gain access to some important data with memory in an expected location and potentially escalate their privileges on the system. | |||||
| CVE-2026-3184 | 2 Kernel, Redhat | 2 Util-linux, Hardened Images | 2026-07-21 | N/A | 3.7 LOW |
| A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access. | |||||
| CVE-2026-42965 | 1 Redhat | 2 Openshift Container Platform, Openshift Router | 2026-07-21 | N/A | 7.7 HIGH |
| A flaw was found in the OpenShift Router. A user with EndpointSlice write access can exploit this vulnerability by creating a Service backed by an FQDN (Fully Qualified Domain Name) EndpointSlice that resolves to a cloud metadata endpoint. This allows the router to proxy requests to the cloud metadata endpoint, leading to the disclosure of instance credentials and other sensitive metadata. This bypasses previous security measures for validating IP addresses. | |||||
| CVE-2026-13325 | 2 Kubevirt, Redhat | 2 Kubevirt, Openshift Virtualization | 2026-07-21 | N/A | 8.5 HIGH |
| A flaw was found in KubeVirt's migration proxy. When spec.configuration.migrations.disableTLS is set to true on the KubeVirt custom resource, the target virt-handler binds a plain TCP listener on all interfaces (0.0.0.0/::) on a random port with no authentication, peer allow-list, or handshake token. This listener proxies directly into the target virt-launcher's virtqemud control socket. An attacker with a running pod on the cluster network can connect to this listener and issue unfiltered libvirt RPC commands against another tenant's virtual machine, including reading VM memory and configuration, modifying VM state via QMP, or destroying the VM. The bind address is unconditionally 0.0.0.0 — configuring a dedicated migration network via migrations.network only changes the advertised migration IP, not the listener bind address, so the port remains reachable on the pod network even when a dedicated migration network is configured. The API documentation describes disableTLS as removing "the additional layer of live migration encryption" without disclosing that it also removes all mutual authentication. | |||||
| CVE-2023-4693 | 2 Gnu, Redhat | 2 Grub2, Enterprise Linux | 2026-07-21 | N/A | 5.3 MEDIUM |
| An out-of-bounds read flaw was found on grub2's NTFS filesystem driver. This issue may allow a physically present attacker to present a specially crafted NTFS file system image to read arbitrary memory locations. A successful attack allows sensitive data cached in memory or EFI variable values to be leaked, presenting a high Confidentiality risk. | |||||
| CVE-2023-4692 | 2 Gnu, Redhat | 2 Grub2, Enterprise Linux | 2026-07-21 | N/A | 7.5 HIGH |
| An out-of-bounds write flaw was found in grub2's NTFS filesystem driver. This issue may allow an attacker to present a specially crafted NTFS filesystem image, leading to grub's heap metadata corruption. In some circumstances, the attack may also corrupt the UEFI firmware heap metadata. As a result, arbitrary code execution and secure boot protection bypass may be achieved. | |||||
| CVE-2026-47774 | 2 Envoyproxy, Redhat | 2 Envoy, Openshift Service Mesh | 2026-07-20 | N/A | 7.5 HIGH |
| Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to versions 1.35.11, 1.36.7, 1.37.3, and 1.38.1, a vulnerability in Envoy's HTTP/2 downstream request processing allows an unauthenticated remote client to trigger excessive memory consumption, potentially resulting in OOM termination of the Envoy process and denial of service. The issue arises from the combination of two behaviors. First, cookie header bytes are not fully accounted for during request header size validation in Envoy. Second, HPACK header block limits in oghttp2/quiche are enforced on encoded bytes without a corresponding limit on total decoded header size. Together, these behaviors allow a malicious client to cause large decoded header allocations while bypassing the intended request header size protections. Versions 1.35.11, 1.36.7, 1.37.3, and 1.38.1 contain a fix. No complete workaround is known short of applying a fix. Possible temporary mitigations include disabling downstream HTTP/2 where operationally feasible; enforcing stricter request header and cookie limits before traffic reaches Envoy; and monitoring Envoy memory usage for abnormal growth under HTTP/2 traffic. | |||||
| CVE-2026-33845 | 2 Gnu, Redhat | 3 Gnutls, Enterprise Linux, Openshift Container Platform | 2026-07-20 | N/A | 7.5 HIGH |
| A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service. | |||||
| CVE-2026-58380 | 2 Gimp, Redhat | 2 Gimp, Enterprise Linux | 2026-07-16 | N/A | 7.3 HIGH |
| A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the pnmscanner_gettoken() function writes a null terminator one byte past the end of a stack-allocated buffer due to an off-by-one error in the loop boundary check. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution. | |||||
| CVE-2026-58384 | 2 Gimp, Redhat | 2 Gimp, Enterprise Linux | 2026-07-16 | N/A | 7.3 HIGH |
| A flaw was found in GIMP's PSD parser. An integer overflow in read_RLE_channel() can cause an undersized heap allocation for the RLE row-length table, after which subsequent per-row writes corrupt heap memory. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution. | |||||
| CVE-2026-12112 | 2 Redhat, Theforeman | 2 Satellite, Foreman | 2026-07-16 | N/A | 7.8 HIGH |
| A flaw was found in the foreman-mcp-server. A session management vulnerability in the MCP Server allows unauthenticated attackers to hijack active administrative sessions due to an improper cache of authenticated client connections, by trusting a non-secret session ID without re-validating authentication tokens and by logging all newly created session IDs to standard logs. This issue can result in privilege escalation and infrastructure-wide code execution. | |||||
| CVE-2026-9073 | 2 Redhat, Theforeman | 2 Satellite, Foreman | 2026-07-15 | N/A | 6.2 MEDIUM |
| A flaw was found in foreman-mcp-server. This component utilizes two distinct logging mechanisms that can expose sensitive session and authentication data. One mechanism logs session identifiers, which are treated as authentication credentials, at an informational level. The other, when debug logging is enabled, incompletely sanitizes HTTP request headers, leading to the cleartext logging of sensitive information such as authorization tokens and API keys. This vulnerability can result in a confidentiality breach, as sensitive authentication data is persisted in plain text within container logs, increasing the risk if logs are forwarded to a centralized platform. | |||||
