| CVE-2026-58012 | 2 Gnome, Redhat | 4 Glib, Enterprise Linux, Hardened Images and 1 more | 2026-08-03 | 6.5 Medium |
| A flaw was found in GLib. A buffer over-read can occur in the g_regex_replace function when used with the `G_REGEX_RAW` compile flag and case-change replacement escapes because the string_append function processes matched substrings using UTF-8 functions that assume valid UTF-8 input, even when the string is treated as raw bytes. This vulnerability can cause a minor information disclosure of 1-5 bytes and a denial of service when the buffer over-read crosses a page boundary. | ||||
| CVE-2026-58011 | 2 Gnome, Redhat | 4 Glib, Enterprise Linux, Hardened Images and 1 more | 2026-08-03 | 6.5 Medium |
| A flaw was found in GLib. An out-of-bounds read of only 2 bytes can occur in the g_date_time_get_ymd function in the glib/gdatetime.c file when an invalid GDateTime object produced by the g_date_time_add_full function is processed. This flaw can corrupt the date output and potentially cause logic errors that may lead to a denial of service. | ||||
| CVE-2026-58010 | 2 Gnome, Redhat | 4 Glib, Enterprise Linux, Hardened Images and 1 more | 2026-08-03 | 6.5 Medium |
| A flaw was found in GLib. An off-by-one error can occur in the gvs_tuple_is_normal function in the glib/gvariant-serialiser.c file when doing an alignment padding check because the bounds check uses > instead of >=, causing an out-of-bounds read of only 1 byte. This issue can cause a minor information disclosure of 1 byte and a denial of service when the out-of-bounds read crosses a page boundary. | ||||
| CVE-2025-14087 | 2 Gnome, Redhat | 15 Glib, Ai Inference Server, Discovery and 12 more | 2026-08-03 | 5.6 Medium |
| A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings. | ||||
| CVE-2026-15779 | 2 Redhat, Samba | 2 Enterprise Linux, Samba | 2026-08-02 | 6.1 Medium |
| A flaw was found in samba's pam_winbind. When mkhomedir is enabled, pam_winbind chowns the target account's home directory without validating the path is not a critical system directory such as /. On affected systems, accounts with / as their home directory (a common default for system accounts) can have this triggered not only by root, but by a non-root user holding a narrow sudo delegation to run commands as that account, causing ownership of / to change and resulting in severe denial of service (SSH, sudo, and package-manager failures). The change does not grant write access to / (which ships with restrictive 0555 permissions on RHEL), so the impact is availability loss rather than further privilege escalation. | ||||
| CVE-2026-3842 | 2 Qemu, Redhat | 4 Qemu, Enterprise Linux, Openshift and 1 more | 2026-08-02 | 7.8 High |
| A flaw was found in QEMU. This vulnerability allows a local attacker within a guest virtual machine to write data beyond its allocated memory. This occurs when cpu_physical_memory_map() returns a shorter length than expected, leading to an out-of-bounds write. Successful exploitation could result in unauthorized access to guest memory or corruption of heap-allocated objects, potentially causing information disclosure, data integrity issues, or a denial of service. | ||||
| CVE-2026-15813 | 1 Redhat | 3 Enterprise Linux, Openshift, Openshift Container Platform | 2026-08-02 | 6.5 Medium |
| A vulnerability was found in the network packet de-fragmentation engine of kronosnet (Version affected <= 1.34). The internal reassembly code does not properly validate sequence numbers of incoming payload fragments. An attacker can exploit this lack of verification by transmitting malformed packets with corrupted sequence parameters. Under specific conditions, this forces the packet processing layer to parse data outside the designated bounds of the internal memory structures, causing an out-of-bounds memory access or heap corruption. This behavior can result in sudden application crashes or system instability. | ||||
| CVE-2026-15588 | 1 Redhat | 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more | 2026-08-02 | 5.3 Medium |
| A denial-of-service and resource exhaustion vulnerability exists within the `GDBus` component of GLib. The `gdbusauth` authentication mechanism fails to enforce proper length limitations on data lines read from a client. An unauthenticated local or remote attacker can exploit this lack of input validation by sending excessively long streams of data, causing the application to consume massive amounts of system memory and CPU, potentially leading to a crash or system hang. | ||||
| CVE-2026-16277 | 1 Redhat | 3 Enterprise Linux, Openshift, Openshift Container Platform | 2026-08-02 | 6.5 Medium |
| A stack-based buffer overflow was found in rpcbind's rpcinfo utility. When querying a remote rpcbind service with `rpcinfo -l`, address information returned by the server is copied into a fixed-size buffer without sufficient bounds checking. A malicious or compromised rpcbind server could use this flaw to crash the rpcinfo client, resulting in a denial of service. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2026-6390 | 1 Redhat | 3 Enterprise Linux, Openshift, Openshift Container Platform | 2026-08-02 | 6.8 Medium |
| A flaw was found in GNU nano's multi-buffer error message handling. When a user opens multiple files at startup and one triggers an ALERT-level error, a specially crafted filename containing printf format specifiers can be reinterpreted. This format string vulnerability may allow an attacker to achieve stack information disclosure, cause a denial of service (crash), or potentially perform arbitrary memory writes. | ||||
| CVE-2026-12353 | 1 Redhat | 3 Certificate System, Dogtag Certificate System, Enterprise Linux | 2026-08-02 | 5.3 Medium |
| An unauthenticated attacker could trigger an Out of Memory condition to crash the Java process for RHCS by repeatedly sending HTTP requests to the TLS endpoint. Depending on how the RHCS server is configured, a manual intervention to restart it may prove necessary. | ||||
| CVE-2026-16730 | 1 Redhat | 5 Enterprise Linux, Hardened Images, Hummingbird and 2 more | 2026-08-02 | 5.5 Medium |
| A flaw was found in dbus-broker. When the process file-descriptor limit is reached, EMFILE/ENFILE errors during peer setup (notably SO_PEERPIDFD) are handled as fatal failures, causing the broker to exit. A local attacker who can open many connections to the user session bus can trigger this and deny service to the desktop session. Flatpak applications can reach the host session bus through the dbus proxy. | ||||
| CVE-2026-17039 | 1 Redhat | 3 Certificate System, Dogtag Certificate System, Enterprise Linux | 2026-08-02 | 3.1 Low |
| A flaw was found in pki-core. The certificate authority (CA) renewal request path does not perform the realm-based authorization check that the enrollment path performs, allowing an authenticated user entitled to one realm to cause a certificate belonging to a different realm to be renewed without that realm's authorization. | ||||
| CVE-2026-15722 | 1 Redhat | 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more | 2026-08-02 | 7.5 High |
| A stack buffer overflow flaw was found in 389 Directory Server (389-ds-base). The get_ruvelement_from_berval() function in repl5_ruv.c copies digit characters from a network-supplied RUV berval into a fixed 16-byte stack buffer without bounds checking. A remote unauthenticated attacker can crash the LDAP server by sending a crafted StartNSDS50ReplicationRequest extended operation containing a replica ID field with more than 16 digit characters. The overflow occurs during payload decoding, before any authorization check. Stack protectors limit impact to denial of service. | ||||
| CVE-2026-11770 | 2 Port389, Redhat | 5 389-ds-base, 389 Directory Server, Directory Server and 2 more | 2026-08-02 | 7.5 High |
| A flaw was found in 389 Directory Server. An unauthenticated remote attacker can inject LDAP search filters into the CleanAllRUV replication status-check extended operation. Because the handler performs the search against cn=config with elevated replication plugin privileges and returns a boolean match result, the attacker can extract sensitive server configuration metadata, including replication bind DNs and password storage scheme information. | ||||
| CVE-2026-18157 | 2 Redhat, Redhatinsights | 2 Enterprise Linux, Yggdrasil-worker-package-manager | 2026-08-02 | 7.8 High |
| A flaw was found in yggdrasil-worker-package-manager. A local attacker with existing access to the system could exploit an argument injection vulnerability in the APT backend. This allows specially crafted package names, which begin with a hyphen, to be misinterpreted as command options by apt-get. Successful exploitation could lead to remote code execution (RCE) with root privileges, enabling the attacker to fully compromise the system's integrity, confidentiality, and availability. | ||||
| CVE-2026-58216 | 2 Redhat, Samba | 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more | 2026-07-31 | 5.3 Medium |
| An out-of-bounds read flaw was found in Samba's Kerberos Key Distribution Center's (KDC) password change (kpasswd) service. When processing malformed ASN.1-encoded Kerberos password change request, Samba server miscalculates the structure size and attempts to read up to six bytes beyond the end of the allocated buffer. While this out-of-bounds read typically results in a harmless decryption failure, if the read hits unmapped memory, it causes the KDC process to crash. An authenticated attacker can send a specially crafted kpasswd request containing malformed ASN.1 data to trigger the out-of-bounds read, which may cause the KDC process to terminate, resulting in a denial of service. | ||||
| CVE-2026-18369 | 1 Redhat | 2 Certificate System, Enterprise Linux | 2026-07-31 | 5.8 Medium |
| A flaw was found in Dogtag PKI's ACME responder where the HTTP-01 challenge validator accepts IP address literals as dns identifiers and follows HTTP redirects without validating that the target is a public address. An unauthenticated ACME account holder can exploit this to perform server-side request forgery (SSRF), making the Dogtag server send HTTP GET requests to internal network services. With the InMemory database backend, the response body of internal targets is disclosed to the attacker through the ACME challenge error. | ||||
| CVE-2026-9150 | 3 Opensuse, Red Hat, Redhat | 11 Libsolv, Red Hat Satellite 6, Enterprise Linux and 8 more | 2026-07-31 | 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. | ||||
| CVE-2026-9149 | 3 Opensuse, Red Hat, Redhat | 12 Libsolv, Red Hat Satellite 6, Enterprise Linux and 9 more | 2026-07-31 | 6.5 Medium |
| A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS). | ||||
