CVE-2026-50659 4 Apple, Linux, Microsoft and 1 more 22 Macos, Linux Kernel, .net and 19 more 2026-08-05 6.5 Medium
Improper encoding or escaping of output in .NET allows an authorized attacker to perform spoofing over a network.
CVE-2026-15945 1 Redhat 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more 2026-08-05 4.3 Medium
A flaw was found in the group search functionality of the Keycloak server's administrative API. When Fine-Grained Admin Permissions (FGAP) v2 is enabled, a delegated administrator can bypass access restrictions to view parent groups they are not authorized to see. By searching for a child group they have permission to view, the system incorrectly returns the full details of the parent group in the response, leading to the disclosure of sensitive group attributes and configuration.
CVE-2026-53704 2 Gstreamer Project, Redhat 4 Gstreamer Plugin, Enterprise Linux, Enterprise Linux Eus and 1 more 2026-08-05 7.1 High
A flaw was found in GStreamer's RealMedia demuxer in the gst-plugins-ugly package. When processing a RealMedia file containing a specially crafted FILEINFO metadata section, the demuxer parses variable-name and variable-value pairs using re_skip_pascal_string() without validating that offsets remain within the mapped buffer. Additionally, the element count controlling the parsing loop is read from attacker-controlled data without validation, which can cause an infinite loop. A crafted RealMedia file can cause the application to crash, hang, or potentially read limited adjacent memory contents.
CVE-2026-53703 2 Gstreamer, Redhat 4 Gstreamer, Enterprise Linux, Enterprise Linux Eus and 1 more 2026-08-05 7.1 High
A vulnerability was found in the GStreamer RealMedia demuxer (gst-plugins-ugly). When processing a RealMedia (.rm) file, the demuxer parses MDPR (media properties) chunks to configure audio streams. For audio stream header versions 4 and 5, the parser reads fields such as codec type, packet size, sample rate, channel count, and extra codec data length from fixed offsets within the chunk without first checking that the chunk contains enough data. If a malicious file provides an MDPR chunk that is too small to contain a complete audio stream header, the parser reads beyond the end of the buffer. This can cause the application to crash. In some cases, bytes read past the buffer boundary may be incorporated into stream metadata, which could result in limited information disclosure.
CVE-2025-5278 1 Redhat 7 Cost Management, Discovery, Enterprise Linux and 4 more 2026-08-05 4.4 Medium
A flaw was found in GNU Coreutils. The sort utility's begfield() function is vulnerable to a heap buffer under-read. The program may access memory outside the allocated buffer if a user runs a crafted command using the traditional key format. A malicious input could lead to a crash or leak sensitive data.
CVE-2026-50257 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-08-04 7.8 High
A use-after-free flaw was found in the X.Org X server and Xwayland in miSyncDestroyFence(). A client that sets up multiple fence triggers can trigger a use-after-free function pointer call. An attacker would connect to the X server to set up a fence and await that fence, then a second X connection destroys the fence, causing the use-after-free. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50262 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-08-04 5.5 Medium
An out-of-bounds read flaw was found in the X.Org X server and Xwayland in __glXDisp_ChangeDrawableAttributes(). A wrong size validation check can read a client-controlled number of bytes, exceeding the request buffer, leading to information disclosure. A write path also exists but requires byte-swapped clients which is disabled by default.
CVE-2026-50258 2 Redhat, X.org 10 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 7 more 2026-08-04 7.8 High
A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. The X server has multiple stack buffers sized XkbMaxShiftLevel * XkbNumKbdGroups but CheckKeyTypes() does not verify or clamp non-canonical key types to XkbMaxShiftLevel. A client can change key types to excessive shift levels and trigger stack overflows. This is caused by an incomplete fix of CVE-2025-26597. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50261 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-08-04 7.8 High
A use-after-free flaw was found in the X.Org X server and Xwayland in SyncChangeCounter(). A client that sets up multiple SyncCounters can trigger a use-after-free when destroying those counters via a second client connection while changing those counters. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50260 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-08-04 7.8 High
A use-after-free flaw was found in the X.Org X server and Xwayland in FreeCounter(). A client that sets up multiple SyncCounters and awaits on those triggers can trigger a use-after-free when destroying those counters via a second client connection. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50259 3 Redhat, X.org, Xorg 12 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 9 more 2026-08-04 7.8 High
A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. _XkbSetMapChecks() declares a fixed-size stack buffer mapWidths[256] indexed by key type index. The helper function CheckKeyTypes() writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50263 2 Redhat, X.org 10 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 7 more 2026-08-04 5.5 Medium
A use-after-free flaw was found in the X.Org X server and Xwayland in CreateSaverWindow(). A client can trigger a use-after-free read after changing window attributes and forcing the screen saver, leading to information disclosure.
CVE-2026-50256 2 Redhat, X.org 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more 2026-08-04 7.8 High
A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias target name length is 1024 bytes. A font alias name between 257 and 1023 bytes causes the X server to copy that name into the undersized stack buffer without further checks. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-18141 1 Redhat 3 Ansible Automation Platform, Ansible Automation Platform Developer, Ansible Automation Platform Inside 2026-08-04 8.2 High
A flaw was found in aap-gateway, a component of Ansible Automation Platform's Event-Driven Ansible (EDA). An unauthenticated remote attacker can bypass mutual Transport Layer Security (mTLS) authentication for event streams. This is achieved by manipulating the event stream URL and forging the HTTP Subject header. The system also inadvertently discloses the expected certificate subject in error messages, which simplifies the attack. This vulnerability allows an attacker to inject arbitrary events into EDA, potentially triggering automated workflows.
CVE-2026-12515 1 Redhat 6 Hardened Images, Hummingbird, Satellite and 3 more 2026-08-04 4.3 Medium
A flaw was found in Katello's of Red Hat Satellite. A content upload functionality where insufficient authorization checks in the ContentUploadsController allowed users with the edit_products permission to query content information for repositories outside the products they were authorized to manage. An authenticated attacker could exploit this issue to determine whether specific content exists within repositories that should otherwise be inaccessible. This issue does not allow unauthorized modification, import, or publication of content.
CVE-2026-12383 1 Redhat 3 Ansible Automation Platform, Ansible Automation Platform Developer, Ansible Automation Platform Inside 2026-08-04 7.5 High
A flaw was found in the Event-Driven Ansible (EDA) server. The ExternalEventStreamViewSet uses permissive access controls (permission_classes=[AllowAny], authentication_classes=[]) and relies solely on the Subject HTTP header value for mTLS authentication without verifying that the header originated from a trusted proxy. Additionally, the expected certificate Distinguished Name is leaked in the 403 error response body. An attacker who can reach the EDA API endpoint with a spoofed Subject header can inject arbitrary events into mTLS-protected event streams, triggering downstream automation actions.
CVE-2025-5318 2 Libssh, Redhat 11 Libssh, Ai Inference Server, Enterprise Linux and 8 more 2026-08-04 5.4 Medium
A flaw was found in the libssh library in versions less than 0.11.2. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior.
CVE-2023-4853 2 Quarkus, Redhat 21 Quarkus, Build Of Optaplanner, Build Of Quarkus and 18 more 2026-08-04 8.1 High
A flaw was found in Quarkus where HTTP security policies are not sanitizing certain character permutations correctly when accepting requests, resulting in incorrect evaluation of permissions. This issue could allow an attacker to bypass the security policy altogether, resulting in unauthorized endpoint access and possibly a denial of service.
CVE-2026-70367 2 Redhat, Stunnel 2 Enterprise Linux, Stunnel 2026-08-04 5.4 Medium
A Server-Side Request Forgery (SSRF) bypass vulnerability exists in “stunnel” 5.79 and lower when configured in SOCKS proxy mode. This flaw allows a client to bypass intended localhost restrictions by using IPv4-mapped IPv6 addresses (e.g., “::ffff:127.0.0.1”) or unspecified addresses ("0.0.0.0", "::"), enabling access to loopback-only services on the "stunnel" host that should not be network-reachable.
CVE-2026-18569 1 Redhat 6 Build Keycloak, Build Of Keycloak, Jboss Data Grid and 3 more 2026-08-04 3.7 Low
A flaw was found in the backchannel logout endpoint of the keycloak-services component, which is part of the Red Hat Build of Keycloak. This component handles authentication and session management for applications. The issue occurs when an OIDC identity provider is configured to skip signature validation. In this specific setup, the system incorrectly accepts logout requests that have no cryptographic signature. An attacker who knows certain technical details about a user's session can use this flaw to force that user to be logged out, potentially disrupting their work.
