| CVE-2026-42010 | 2 Gnu, Redhat | 4 Gnutls, Enterprise Linux, Hardened Images and 1 more | 2026-06-10 | N/A | 7.1 HIGH |
| A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process. | |||||
| CVE-2026-3012 | 2 Redhat, Samba | 3 Enterprise Linux, Openshift Container Platform, Samba | 2026-06-10 | N/A | 8.0 HIGH |
| A flaw was found in Samba’s certificate auto-enrollment Group Policy handling. When certificate auto-enrollment is enabled, Samba may retrieve a CA certificate over an unencrypted HTTP connection and install it into the local trust store without proper verification. An attacker with the ability to intercept or redirect network traffic could exploit this behavior to supply a malicious certificate authority certificate, potentially allowing interception or spoofing of trusted communications. | |||||
| CVE-2026-2340 | 2 Redhat, Samba | 3 Enterprise Linux, Openshift Container Platform, Samba | 2026-06-10 | N/A | 6.5 MEDIUM |
| A flaw was found in Samba’s vfs_worm module. The module is intended to provide write-once, read-many (WORM) protections by preventing modification of files after a configurable grace period. Due to insufficient validation during rename operations, an authenticated user with write access to a share could overwrite a protected file by renaming a newly created file over the existing WORM-protected file. | |||||
| CVE-2026-1933 | 2 Redhat, Samba | 3 Enterprise Linux, Openshift Container Platform, Samba | 2026-06-10 | N/A | 7.1 HIGH |
| A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-only exports. This could allow modification of SMB-visible file behavior, including converting files into symbolic links or other reparse point types. | |||||
| CVE-2026-5119 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-06-09 | N/A | 5.9 MEDIUM |
| A flaw was found in libsoup. When establishing HTTPS tunnels through a configured HTTP proxy, sensitive session cookies are transmitted in cleartext within the initial HTTP CONNECT request. A network-positioned attacker or a malicious HTTP proxy can intercept these cookies, leading to potential session hijacking or user impersonation. | |||||
| CVE-2026-50259 | 2 Redhat, X.org | 3 Enterprise Linux, X Server, Xwayland | 2026-06-08 | N/A | 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-2026-42009 | 2 Gnu, Redhat | 14 Gnutls, Enterprise Linux, Enterprise Linux For Els and 11 more | 2026-06-08 | N/A | 7.5 HIGH |
| A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined behavior, resulting in a denial of service. | |||||
| CVE-2026-50258 | 2 Redhat, X.org | 3 Enterprise Linux, X Server, Xwayland | 2026-06-08 | N/A | 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 | 3 Enterprise Linux, X Server, Xwayland | 2026-06-08 | N/A | 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 | 3 Enterprise Linux, X Server, Xwayland | 2026-06-08 | N/A | 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-2026-34002 | 2 Redhat, X.org | 2 Enterprise Linux, X Server | 2026-06-08 | N/A | 6.1 MEDIUM |
| A flaw was found in the X.Org X server. This vulnerability, an out-of-bounds read, affects the XKB (X Keyboard Extension) modifier map handling. An attacker with access to the X11 server can exploit this by sending a malformed request, which causes the server to read beyond its intended memory boundaries. This can lead to the exposure of sensitive information or cause the server to crash, resulting in a denial of service. | |||||
| CVE-2026-34000 | 2 Redhat, X.org | 2 Enterprise Linux, X Server | 2026-06-08 | N/A | 6.1 MEDIUM |
| A flaw was found in the X.Org X server. This out-of-bounds read vulnerability in the XKB geometry processing, specifically within the `CheckSetGeom()` and `XkbAddGeomKeyAlias` functions, allows an attacker to read uninitialized or out-of-bounds memory. An attacker with a connection to the X11 server, either locally or remotely, can exploit this without user interaction. This could lead to the disclosure of memory contents or cause a denial of service by crashing the server. | |||||
| CVE-2025-5372 | 2 Libssh, Redhat | 3 Libssh, Enterprise Linux, Openshift Container Platform | 2026-06-08 | N/A | 5.0 MEDIUM |
| A flaw was found in libssh versions built with OpenSSL versions older than 3.0, specifically in the ssh_kdf() function responsible for key derivation. Due to inconsistent interpretation of return values where OpenSSL uses 0 to indicate failure and libssh uses 0 for success—the function may mistakenly return a success status even when key derivation fails. This results in uninitialized cryptographic key buffers being used in subsequent communication, potentially compromising SSH sessions' confidentiality, integrity, and availability. | |||||
| CVE-2024-0193 | 2 Linux, Redhat | 23 Linux Kernel, Codeready Linux Builder, Codeready Linux Builder For Eus and 20 more | 2026-06-05 | N/A | 7.8 HIGH |
| A use-after-free flaw was found in the netfilter subsystem of the Linux kernel. If the catchall element is garbage-collected when the pipapo set is removed, the element can be deactivated twice. This can cause a use-after-free issue on an NFT_CHAIN object or NFT_OBJECT object, allowing a local unprivileged user with CAP_NET_ADMIN capability to escalate their privileges on the system. | |||||
| CVE-2022-0492 | 6 Canonical, Debian, Fedoraproject and 3 more | 33 Ubuntu Linux, Debian Linux, Fedora and 30 more | 2026-06-03 | 6.9 MEDIUM | 7.8 HIGH |
| A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly. | |||||
| CVE-2026-2100 | 2 P11-kit Project, Redhat | 3 P11-kit, Enterprise Linux, Hardened Images | 2026-06-02 | N/A | 5.3 MEDIUM |
| A flaw was found in p11-kit. A remote attacker could exploit this vulnerability by calling the C_DeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL. This could lead to the RPC-client attempting to return an uninitialized value, potentially resulting in a NULL dereference or undefined behavior. This issue may cause an application level denial of service or other unpredictable system states. | |||||
| CVE-2026-3497 | 4 Canonical, Debian, Openbsd and 1 more | 4 Ubuntu Linux, Debian Linux, Openssh and 1 more | 2026-06-02 | N/A | 7.5 HIGH |
| Vulnerability in the OpenSSH GSSAPI delta included in various Linux distributions. This vulnerability affects the GSSAPI patches added by various Linux distributions and does not affect the OpenSSH upstream project itself. The usage of sshpkt_disconnect() on an error, which does not terminate the process, allows an attacker to send an unexpected GSSAPI message type during the GSSAPI key exchange to the server, which will call the underlying function and continue the execution of the program without setting the related connection variables. As the variables are not initialized to NULL the code later accesses those uninitialized variables, accessing random memory, which could lead to undefined behavior. The recommended workaround is to use ssh_packet_disconnect() instead, which does terminate the process. The impact of the vulnerability depends heavily on the compiler flag hardening configuration. | |||||
| CVE-2026-2376 | 1 Redhat | 3 Enterprise Linux, Mirror Registry, Quay | 2026-06-02 | N/A | 4.9 MEDIUM |
| A flaw was found in mirror-registry where an authenticated user can trick the system into accessing unintended internal or restricted systems by providing malicious web addresses. When the application processes these addresses, it automatically follows redirects without verifying the final destination, allowing attackers to route requests to systems they should not have access to. | |||||
| CVE-2026-9064 | 1 Redhat | 3 389 Directory Server, Directory Server, Enterprise Linux | 2026-06-02 | N/A | 7.5 HIGH |
| A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() function in the LDAP server does not enforce an upper bound on the number of controls per LDAP message. A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of thousands of minimal controls within the default maximum BER message size (2 MB), causing excessive CPU consumption and heap allocation on the server. Under concurrent exploitation, this leads to significant latency degradation, worker thread starvation, or out-of-memory termination, resulting in a denial of service. | |||||
| CVE-2026-9150 | 2 Opensuse, Redhat | 6 Libsolv, Enterprise Linux, Hardened Images and 3 more | 2026-06-02 | N/A | 6.5 MEDIUM |
| A flaw was found in libsolv. This stack-based buffer overflow vulnerability occurs in libsolv's Debian metadata parser when processing specially crafted Debian repository metadata. An attacker could exploit this by providing malicious SHA384 or SHA512 checksum tags, leading to memory corruption and a denial of service (DoS) in the affected system. | |||||
