| A flaw was identified in the NTLM authentication handling of the libsoup HTTP library, used by GNOME and other applications for network communication. When processing extremely long passwords, an internal size calculation can overflow due to improper use of signed integers. This results in incorrect memory allocation on the stack, followed by unsafe memory copying. As a result, applications using libsoup may crash unexpectedly, creating a denial-of-service risk. | ||||
| CVE-2025-61664 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-06-30 | 4.9 Medium |
| A vulnerability in the GRUB2 bootloader has been identified in the normal module. This flaw, a memory Use After Free issue, occurs because the normal_exit command is not properly unregistered when its related module is unloaded. An attacker can exploit this condition by invoking the command after the module has been removed, causing the system to improperly access a previously freed memory location. This leads to a system crash or possible impacts in data confidentiality and integrity. | ||||
| CVE-2025-61662 | 2 Gnu, Redhat | 10 Grub2, Enterprise Linux, Enterprise Linux Eus and 7 more | 2026-06-30 | 7.8 High |
| A Use-After-Free vulnerability has been discovered in GRUB's gettext module. This flaw stems from a programming error where the gettext command remains registered in memory after its module is unloaded. An attacker can exploit this condition by invoking the orphaned command, causing the application to access a memory location that is no longer valid. An attacker could exploit this vulnerability to cause grub to crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not discarded. | ||||
| CVE-2025-61663 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-06-30 | 4.9 Medium |
| A vulnerability has been identified in the GRUB2 bootloader's normal command that poses an immediate Denial of Service (DoS) risk. This flaw is a Use-after-Free issue, caused because the normal command is not properly unregistered when the module is unloaded. An attacker who can execute this command can force the system to access memory locations that are no longer valid. Successful exploitation leads directly to system instability, which can result in a complete crash and halt system availability. Impact on the data integrity and confidentiality is also not discarded. | ||||
| CVE-2025-61661 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-06-30 | 4.8 Medium |
| A vulnerability has been identified in the GRUB (Grand Unified Bootloader) component. This flaw occurs because the bootloader mishandles string conversion when reading information from a USB device, allowing an attacker to exploit inconsistent length values. A local attacker can connect a maliciously configured USB device during the boot sequence to trigger this issue. A successful exploitation may lead GRUB to crash, leading to a Denial of Service. Data corruption may be also possible, although given the complexity of the exploit the impact is most likely limited. | ||||
| CVE-2025-59089 | 1 Redhat | 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more | 2026-06-30 | 5.9 Medium |
| If an attacker causes kdcproxy to connect to an attacker-controlled KDC server (e.g. through server-side request forgery), they can exploit the fact that kdcproxy does not enforce bounds on TCP response length to conduct a denial-of-service attack. While receiving the KDC's response, kdcproxy copies the entire buffered stream into a new buffer on each recv() call, even when the transfer is incomplete, causing excessive memory allocation and CPU usage. Additionally, kdcproxy accepts incoming response chunks as long as the received data length is not exactly equal to the length indicated in the response header, even when individual chunks or the total buffer exceed the maximum length of a Kerberos message. This allows an attacker to send unbounded data until the connection timeout is reached (approximately 12 seconds), exhausting server memory or CPU resources. Multiple concurrent requests can cause accept queue overflow, denying service to legitimate clients. | ||||
| CVE-2025-54771 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-06-30 | 4.9 Medium |
| A use-after-free vulnerability has been identified in the GNU GRUB (Grand Unified Bootloader). The flaw occurs because the file-closing process incorrectly retains a memory pointer, leaving an invalid reference to a file system structure. An attacker could exploit this vulnerability to cause grub to crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not discarded. | ||||
| CVE-2025-54770 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-06-30 | 4.9 Medium |
| A vulnerability has been identified in the GRUB2 bootloader's network module that poses an immediate Denial of Service (DoS) risk. This flaw is a Use-after-Free issue, caused because the net_set_vlan command is not properly unregistered when the network module is unloaded from memory. An attacker who can execute this command can force the system to access memory locations that are no longer valid. Successful exploitation leads directly to system instability, which can result in a complete crash and halt system availability | ||||
| CVE-2025-47712 | 2 Nbdkit Project, Redhat | 4 Nbdkit, Advanced Virtualization, Enterprise Linux and 1 more | 2026-06-30 | 6.5 Medium |
| A flaw exists in the nbdkit "blocksize" filter that can be triggered by a specific type of client request. When a client requests block status information for a very large data range, exceeding a certain limit, it causes an internal error in the nbdkit, leading to a denial of service. | ||||
| CVE-2025-47711 | 2 Nbdkit Project, Redhat | 4 Nbdkit, Advanced Virtualization, Enterprise Linux and 1 more | 2026-06-30 | 6.5 Medium |
| There's a flaw in the nbdkit server when handling responses from its plugins regarding the status of data blocks.
