| CVE-2026-50259 | 3 Redhat, X.org, Xorg | 5 Enterprise Linux, X Server, Xorg-server and 2 more | 2026-06-25 | 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-2026-50258 | 2 Redhat, X.org | 3 Enterprise Linux, X Server, Xwayland | 2026-06-25 | 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-2026-50257 | 2 Redhat, X.org | 4 Enterprise Linux, X Server, Xorg-server and 1 more | 2026-06-25 | 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-2026-50256 | 2 Redhat, X.org | 4 Enterprise Linux, X Server, Xorg-server and 1 more | 2026-06-25 | 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-2026-12515 | 1 Redhat | 3 Hardened Images, Hummingbird, Satellite | 2026-06-25 | 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-2026-12112 | 1 Redhat | 1 Satellite | 2026-06-25 | 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-2024-45783 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhivos | 2026-06-25 | 4.4 Medium |
| A flaw was found in grub2. When failing to mount an HFS+ grub, the hfsplus filesystem driver doesn't properly set an ERRNO value. This issue may lead to a NULL pointer access. | ||||
| CVE-2024-45782 | 2 Gnu, Redhat | 5 Grub2, Enterprise Linux, Openshift and 2 more | 2026-06-25 | 7.8 High |
| A flaw was found in the HFS filesystem. When reading an HFS volume's name at grub_fs_mount(), the HFS filesystem driver performs a strcpy() using the user-provided volume name as input without properly validating the volume name's length. This issue may read to a heap-based out-of-bounds writer, impacting grub's sensitive data integrity and eventually leading to a secure boot protection bypass. | ||||
| CVE-2024-45781 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhivos | 2026-06-25 | 6.7 Medium |
| A flaw was found in grub2. When reading a symbolic link's name from a UFS filesystem, grub2 fails to validate the string length taken as an input. The lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and eventually allowing an attacker to circumvent secure boot protections. | ||||
| CVE-2024-45780 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhivos | 2026-06-25 | 6.7 Medium |
| A flaw was found in grub2. When reading tar files, grub2 allocates an internal buffer for the file name. However, it fails to properly verify the allocation against possible integer overflows. It's possible to cause the allocation length to overflow with a crafted tar file, leading to a heap out-of-bounds write. This flaw eventually allows an attacker to circumvent secure boot protections. | ||||
| CVE-2024-45778 | 2 Gnu, Redhat | 5 Grub2, Enterprise Linux, Openshift and 2 more | 2026-06-25 | 4.1 Medium |
| A stack overflow flaw was found when reading a BFS file system. A crafted BFS filesystem may lead to an uncontrolled loop, causing grub2 to crash. | ||||
| CVE-2024-45777 | 2 Gnu, Redhat | 4 Grub2, Enterprise Linux, Openshift and 1 more | 2026-06-25 | 6.7 Medium |
| A flaw was found in grub2. The calculation of the translation buffer when reading a language .mo file in grub_gettext_getstr_from_position() may overflow, leading to a Out-of-bound write. This issue can be leveraged by an attacker to overwrite grub2's sensitive heap data, eventually leading to the circumvention of secure boot protections. | ||||
| CVE-2024-45776 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhivos | 2026-06-25 | 6.7 Medium |
| When reading the language .mo file in grub_mofile_open(), grub2 fails to verify an integer overflow when allocating its internal buffer. A crafted .mo file may lead the buffer size calculation to overflow, leading to out-of-bound reads and writes. This flaw allows an attacker to leak sensitive data or overwrite critical data, possibly circumventing secure boot protections. | ||||
| CVE-2024-45774 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhivos | 2026-06-25 | 6.7 Medium |
| A flaw was found in grub2. A specially crafted JPEG file can cause the JPEG parser of grub2 to incorrectly check the bounds of its internal buffers, resulting in an out-of-bounds write. The possibility of overwriting sensitive information to bypass secure boot protections is not discarded. | ||||
| CVE-2025-0690 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhivos | 2026-06-25 | 6.1 Medium |
| The read command is used to read the keyboard input from the user, while reads it keeps the input length in a 32-bit integer value which is further used to reallocate the line buffer to accept the next character. During this process, with a line big enough it's possible to make this variable to overflow leading to a out-of-bounds write in the heap based buffer. This flaw may be leveraged to corrupt grub's internal critical data and secure boot bypass is not discarded as consequence. | ||||
| CVE-2025-0689 | 2 Gnu, Redhat | 4 Grub2, Enterprise Linux, Openshift and 1 more | 2026-06-25 | 7.8 High |
| When reading data from disk, the grub's UDF filesystem module utilizes the user controlled data length metadata to allocate its internal buffers. In certain scenarios, while iterating through disk sectors, it assumes the read size from the disk is always smaller than the allocated buffer size which is not guaranteed. A crafted filesystem image may lead to a heap-based buffer overflow resulting in critical data to be corrupted, resulting in the risk of arbitrary code execution by-passing secure boot protections. | ||||
| CVE-2025-0622 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhivos | 2026-06-25 | 6.4 Medium |
| A flaw was found in command/gpg. In some scenarios, hooks created by loaded modules are not removed when the related module is unloaded. This flaw allows an attacker to force grub2 to call the hooks once the module that registered it was unloaded, leading to a use-after-free vulnerability. If correctly exploited, this vulnerability may result in arbitrary code execution, eventually allowing the attacker to bypass secure boot protections. | ||||
| CVE-2025-0620 | 2 Redhat, Samba | 4 Enterprise Linux, Openshift, Rhivos and 1 more | 2026-06-25 | 4.9 Medium |
| A flaw was found in Samba. The smbd service daemon does not pick up group membership changes when re-authenticating an expired SMB session. This issue can expose file shares until clients disconnect and then connect again. | ||||
| CVE-2025-0306 | 1 Redhat | 3 Enterprise Linux, Rhivos, Storage | 2026-06-25 | 7.4 High |
| A vulnerability was found in Ruby. The Ruby interpreter is vulnerable to the Marvin Attack. This attack allows the attacker to decrypt previously encrypted messages or forge signatures by exchanging a large number of messages with the vulnerable service. | ||||
| CVE-2024-52616 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhivos | 2026-06-25 | 5.3 Medium |
| A flaw was found in the Avahi-daemon, where it initializes DNS transaction IDs randomly only once at startup, incrementing them sequentially after that. This predictable behavior facilitates DNS spoofing attacks, allowing attackers to guess transaction IDs. | ||||
