CVE-2018-10902 4 Canonical, Debian, Linux and 1 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2026-07-07 4.6 MEDIUM 7.8 HIGH
It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation.
CVE-2026-12892 2 Gstreamer, Redhat 2 Gstreamer, Enterprise Linux 2026-07-06 N/A 4.4 MEDIUM
A flaw was found in GStreamer's gst-plugins-bad package. When processing a specially crafted H.264 video file containing malformed MVC or SVC extension slice NAL units, a 1-byte heap out-of-bounds read can occur during parsing. This happens when the parser attempts to check slice boundary information without first verifying that the NAL unit contains enough data beyond the extension header. An attacker could exploit this by tricking a user into opening a malicious H.264 video file, potentially causing the application to crash or leak a single byte of heap memory.
CVE-2024-51127 1 Redhat 1 Hornetq 2026-07-05 N/A 7.1 HIGH
An issue in the createTempFile method of hornetq v2.4.9 allows attackers to arbitrarily overwrite files or access sensitive information.
CVE-2026-12388 1 Redhat 1 Build Of Keycloak 2026-07-01 N/A 6.5 MEDIUM
A flaw was found in the Identity Provider (IdP) mapper component of Keycloak, which is used to manage how user information from external services is mapped to Keycloak users. An administrator with limited permissions to manage identity providers can exploit this flaw by creating a "Hardcoded Role" mapper that assigns high-level administrative roles (like realm-admin) to themselves or others. This allows a restricted administrator to bypass security checks and gain full control over the entire realm.
CVE-2026-9705 1 Redhat 1 Build Of Keycloak 2026-07-01 N/A 6.5 MEDIUM
A flaw was found in Keycloak's client registration service. A remote attacker, possessing a previously issued Registration Access Token (RAT), could exploit this vulnerability to re-enable a client that an administrator had explicitly disabled. This bypasses security controls, allowing the attacker to reset the client's secret and potentially regain privileged API access. The primary impact includes unauthorized information disclosure and potential integrity compromise.
CVE-2026-9799 1 Redhat 1 Build Of Keycloak 2026-07-01 N/A 4.6 MEDIUM
A flaw was found in org.keycloak.authorization. An authenticated user with a granted User-Managed Access (UMA) permission ticket for one resource can exploit this by using a specific permission request prefix to bypass per-resource access control. This allows the user to gain unauthorized access to all resources of that type within the same resource server, even if they do not have a ticket for those specific resources. This vulnerability requires the resource server to be configured in PERMISSIVE policy enforcement mode and affects typed resources with ownerManagedAccess enabled, where no explicit policy protects the resource type. The primary consequence is unauthorized information disclosure or modification of resources.
CVE-2026-11820 1 Redhat 1 Enterprise Linux 2026-07-01 N/A 6.5 MEDIUM
A flaw was found in the community.general Ansible collection's nexmo module. The module constructs HTTP requests to the Vonage/Nexmo SMS API by encoding API credentials (api_key and api_secret) into URL query parameters and sending them via GET requests. This causes credentials to be exposed in web server access logs, proxy logs, HTTP Referer headers, and network monitoring tools, despite the Ansible argument specification marking these parameters as no_log. An attacker with access to any of these logging or monitoring points can obtain the full API credentials and gain unauthorized access to the victim's Vonage/Nexmo account.
CVE-2026-12891 2 Gstreamer, Redhat 2 Gstreamer, Enterprise Linux 2026-07-01 N/A 4.3 MEDIUM
A flaw was found in the GStreamer gst-plugins-bad package. When processing a malformed H.266/VVC video stream with a crafted aspect ratio indicator value, the H.266 parser performs an out-of-bounds read of up to 8 bytes from adjacent memory. This flaw allows an attacker to craft a malicious H.266 video file or stream that, when processed by a GStreamer-based application, could leak limited memory contents through video metadata, potentially exposing sensitive information from the application's address space.
CVE-2026-9083 1 Redhat 1 Build Of Keycloak 2026-07-01 N/A 4.9 MEDIUM
A flaw was found in Keycloak. A realm administrator with the "manage-realm" role can exploit this vulnerability by submitting an arbitrary filesystem path as a keystore parameter when creating a key provider component. This allows the administrator to probe arbitrary filesystem paths, determining which files exist and are readable by the Keycloak process. This information disclosure could be used to identify high-value targets for follow-on attacks.
CVE-2025-62231 4 Debian, Ibm, Redhat and 1 more 11 Debian Linux, Aix, Vios and 8 more 2026-07-01 N/A 7.3 HIGH
A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash.
CVE-2025-62230 4 Debian, Ibm, Redhat and 1 more 11 Debian Linux, Aix, Vios and 8 more 2026-07-01 N/A 7.3 HIGH
A flaw was discovered in the X.Org X server’s X Keyboard (Xkb) extension when handling client resource cleanup. The software frees certain data structures without properly detaching related resources, leading to a use-after-free condition. This can cause memory corruption or a crash when affected clients disconnect.
CVE-2026-11791 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2026-06-30 N/A 5.0 MEDIUM
A flaw was found in 389 Directory Server. During schema reload, the attr_syntax_swap_ht() function unconditionally frees attribute syntax information nodes, bypassing the refcount-based deferred deletion used elsewhere in the attribute syntax subsystem. If an administrator triggers schema reload while concurrent LDAP query traffic is active, worker threads may access freed memory, resulting in use-after-free or double-free and a denial of service (server crash).
CVE-2025-6199 2 Gnome, Redhat 2 Gdkpixbuf, Enterprise Linux 2026-06-30 N/A 3.3 LOW
A flaw was found in the GIF parser of GdkPixbuf’s LZW decoder. When an invalid symbol is encountered during decompression, the decoder sets the reported output size to the full buffer length rather than the actual number of written bytes. This logic error results in uninitialized sections of the buffer being included in the output, potentially leaking arbitrary memory contents in the processed image.
CVE-2025-6035 2 Gimp, Redhat 2 Gimp, Enterprise Linux 2026-06-30 N/A 6.1 MEDIUM
A flaw was found in GIMP. An integer overflow vulnerability exists in the GIMP "Despeckle" plug-in. The issue occurs due to unchecked multiplication of image dimensions, such as width, height, and bytes-per-pixel (img_bpp), which can result in allocating insufficient memory and subsequently performing out-of-bounds writes. This issue could lead to heap corruption, a potential denial of service (DoS), or arbitrary code execution in certain scenarios.
CVE-2025-4478 2 Freerdp, Redhat 2 Freerdp, Enterprise Linux 2026-06-30 N/A 6.5 MEDIUM
A flaw was found in the FreeRDP used by Anaconda's remote install feature, where a crafted RDP packet could trigger a segmentation fault. This issue causes the service to crash and remain defunct, resulting in a denial of service. It occurs pre-boot and is likely due to a NULL pointer dereference. Rebooting is required to recover the system.
CVE-2024-8443 2 Opensc Project, Redhat 2 Opensc, Enterprise Linux 2026-06-30 N/A 2.9 LOW
A heap-based buffer overflow vulnerability was found in the libopensc OpenPGP driver. A crafted USB device or smart card with malicious responses to the APDUs during the card enrollment process using the `pkcs15-init` tool may lead to out-of-bound rights, possibly resulting in arbitrary code execution.
CVE-2024-45620 2 Opensc Project, Redhat 2 Opensc, Enterprise Linux 2026-06-30 N/A 3.9 LOW
A vulnerability was found in the pkcs15-init tool in OpenSC. An attacker could use a crafted USB Device or Smart Card, which would present the system with a specially crafted response to APDUs. When buffers are partially filled with data, initialized parts of the buffer can be incorrectly accessed.
