| CVE-2026-54228 | 1 Redhat | 1 Enterprise Linux | 2026-06-15 | 7.8 High |
| A time-of-check time-of-use (TOCTOU) race condition was found in the abrt-dbus D-Bus service's SetElement method. Between dump directory creation and post-create event execution, any local user can call SetElement to write arbitrary text files into the root-owned dump directory, bypassing package validation and allowing crashes of unpackaged binaries to survive post-create processing. | ||||
| CVE-2017-12174 | 2 Apache, Redhat | 5 Artemis, Enterprise Linux, Hornetq and 2 more | 2026-06-15 | 7.5 High |
| It was found that when Artemis and HornetQ before 2.4.0 are configured with UDP discovery and JGroups discovery a huge byte array is created when receiving an unexpected multicast message. This may result in a heap memory exhaustion, full GC, or OutOfMemoryError. | ||||
| CVE-2026-54229 | 1 Redhat | 1 Enterprise Linux | 2026-06-15 | 7 High |
| A race condition was found in the abrt-dbus D-Bus service's ChownProblemDir method. ChownProblemDir opens the dump directory with DD_OPEN_READONLY and calls dd_chown to change ownership of all files to the caller's uid, succeeding even while post-create event handlers hold a write lock. This allows an attacker to gain filesystem-level control of the dump directory while privileged event scripts are still running. | ||||
| CVE-2025-5372 | 2 Libssh, Redhat | 8 Libssh, Enterprise Linux, Openshift and 5 more | 2026-06-15 | 5 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-2026-53702 | 1 Redhat | 1 Enterprise Linux | 2026-06-13 | 6.5 Medium |
| A stack buffer overflow flaw was found in the GStreamer H.265 codec parser library (gst-plugins-bad). When parsing a buffering period SEI message, the parser uses an incorrect loop bound derived from cpb_cnt_minus1[i] (the loop index) instead of the sub-layer 0 CPB count cpb_cnt_minus1[0] from the referenced Sequence Parameter Set. A crafted H.265 video file or stream can cause the parser to write beyond the bounds of stack-allocated CPB delay arrays, resulting in a crash or potential stack memory corruption. | ||||
| CVE-2026-11774 | 1 Redhat | 3 Directory Server, Enterprise Linux, Redhat Directory Server | 2026-06-12 | 7.6 High |
| An integer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). In sasl_io_start_packet(), adding sizeof(uint32_t) to a crafted SASL packet length prefix of 0xFFFFFFFC causes unsigned wraparound to zero, bypassing the nsslapd-maxsasliosize limit and leading to a heap buffer overflow of up to approximately 2 megabytes of attacker-controlled data. After a successful SASL bind with integrity protection (SSF > 0), a remote attacker can cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE). In FreeIPA and Red Hat Identity Management deployments, any domain user with a valid Kerberos ticket, enrolled host, or service account can trigger this vulnerability over the network. This flaw is independent of CVE-2025-14905, which patched schema.c only and did not modify sasl_io.c. | ||||
| CVE-2026-48914 | 1 Redhat | 5 Enterprise Linux, Enterprise Linux For Nvidia 26, Enterprise Linux Nvidia and 2 more | 2026-06-12 | 6.7 Medium |
| A flaw was found in QEMU's virtio-blk device. The issue arises because the device does not properly validate the size of input descriptors before writing data. A malicious guest with high privileges could exploit this vulnerability by submitting a malformed virtio-blk SCSI request, leading to an out-of-bounds write in the host heap memory and a potential denial of service (DoS) for the QEMU process. | ||||
| CVE-2026-11785 | 1 Redhat | 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more | 2026-06-12 | 4.3 Medium |
| A flaw was found in 389 Directory Server. A type confusion in the SSO token extended operation handler causes partial stack address information to be disclosed in LDAP responses to authenticated users. | ||||
| CVE-2026-11786 | 1 Redhat | 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more | 2026-06-12 | 1.9 Low |
| A flaw was found in 389 Directory Server. The LDIF parser reads past the end of a heap buffer when processing attribute types with trailing semicolons during database import, causing an out-of-bounds read detectable under memory instrumentation. | ||||
| CVE-2026-11787 | 1 Redhat | 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more | 2026-06-12 | 5 Medium |
| A flaw was found in 389 Directory Server. The ldap_utf8prev() function reads bytes before the start of a buffer without bounds checking, causing a heap buffer over-read in string filter parsing that may influence internal filter processing behavior. | ||||
| CVE-2026-11788 | 1 Redhat | 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more | 2026-06-12 | 5.9 Medium |
| A flaw was found in 389 Directory Server. The dereference control plugin does not check for allocation failure before using a BER structure, allowing an unauthenticated remote attacker to crash the LDAP server when the system is under memory pressure. | ||||
| CVE-2026-11850 | 1 Redhat | 3 Enterprise Linux, Hummingbird, Openshift | 2026-06-12 | 5 Medium |
| An integer underflow vulnerability was found in MIT krb5 in the berval2tl_data() function in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c. The function performs an unsigned subtraction (bv_len - 2) without a prior bounds check. When bv_len is 0 or 1, the subtraction wraps to a large value which is then truncated to uint16_t, yielding 0xFFFE (65534) or 0xFFFF (65535). The subsequent malloc succeeds and memcpy reads up to 65534 bytes from a 0-1 byte buffer, resulting in a heap out-of-bounds read. The attack vector involves a malicious or compromised LDAP KDB backend returning a krbExtraData attribute with bv_len < 2, triggering the underflow when the KDC or kadmind reads principal data. | ||||
| CVE-2026-53701 | 1 Redhat | 1 Enterprise Linux | 2026-06-11 | 6.5 Medium |
| An out-of-bounds write vulnerability was found in GStreamer's H.266/VVC PPS picture partition parser in gst-plugins-bad. In the multi-slice-in-tile processing of gst_h266_parser_parse_picture_partition() (gsth266parser.c), the loop iterates without checking that the slice index stays within bounds, writing past three fixed-size arrays (slice_height_in_ctus, slice_top_left_ctu_x, slice_top_left_ctu_y) in the GstH266PPS structure. While the initial proof-of-concept demonstrated a 4-byte out-of-bounds write, the code permits larger writes across multiple iterations. A crafted H.266/VVC media file can trigger this vulnerability. | ||||
| CVE-2025-23150 | 3 Debian, Linux, Redhat | 3 Debian Linux, Linux Kernel, Enterprise Linux | 2026-06-11 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ext4: fix off-by-one error in do_split Syzkaller detected a use-after-free issue in ext4_insert_dentry that was caused by out-of-bounds access due to incorrect splitting in do_split.

Found by Linux Verification Center (linuxtesting.org) with Syzkaller. | ||||
| CVE-2026-11884 | 1 Redhat | 3 Directory Server, Enterprise Linux, Redhat Directory Server | 2026-06-11 | 6.5 Medium |
| A heap buffer overflow flaw was found in 389 Directory Server. When serializing objectclass definitions, the oc_superior (SUP) field length is omitted from buffer size calculations in read_schema_dse() and schema_oc_to_string(), but the field is still written via strcat(). An attacker with Directory Manager privileges, or a compromised replication supplier, can trigger a server crash by creating objectclasses with long SUP values. This is an incomplete fix variant of CVE-2025-14905. | ||||
| CVE-2026-28369 | 1 Redhat | 17 Apache Camel Hawtio, Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot and 14 more | 2026-06-10 | 8.7 High |
| A flaw was found in Undertow. When Undertow receives an HTTP request where the first header line starts with one or more spaces, it incorrectly processes the request by stripping these leading spaces. This behavior, which violates HTTP standards, can be exploited by a remote attacker to perform request smuggling. Request smuggling allows an attacker to bypass security mechanisms, access restricted information, or manipulate web caches, potentially leading to unauthorized actions or data exposure. | ||||
| CVE-2026-28368 | 1 Redhat | 17 Apache Camel Hawtio, Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot and 14 more | 2026-06-10 | 8.7 High |
| A flaw was found in Undertow. This vulnerability allows a remote attacker to construct specially crafted requests where header names are parsed differently by Undertow compared to upstream proxies. This discrepancy in header interpretation can be exploited to launch request smuggling attacks, potentially bypassing security controls and accessing unauthorized resources. | ||||
| CVE-2026-28367 | 1 Redhat | 17 Apache Camel Hawtio, Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot and 14 more | 2026-06-10 | 8.7 High |
| A flaw was found in Undertow. A remote attacker can exploit this vulnerability by sending `\r\r\r` as a header block terminator. This can be used for request smuggling with certain proxy servers, such as older versions of Apache Traffic Server and Google Cloud Classic Application Load Balancer, potentially leading to unauthorized access or manipulation of web requests. | ||||
| CVE-2026-45591 | 2 Microsoft, Redhat | 5 .net, Asp.net Core, Visual Studio 2026 and 2 more | 2026-06-10 | 7.5 High |
| Uncontrolled resource consumption in ASP.NET Core allows an unauthorized attacker to deny service over a network. | ||||
| CVE-2026-45491 | 2 Microsoft, Redhat | 3 .net, Enterprise Linux, Hummingbird | 2026-06-10 | 6.2 Medium |
| Improper link resolution before file access ('link following') in .NET allows an unauthorized attacker to perform tampering locally. | ||||
