CVE-2026-42010 2 Gnu, Redhat 14 Gnutls, Discovery, Enterprise Linux and 11 more 2026-06-29 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-2026-42009 2 Gnu, Redhat 24 Gnutls, Discovery, Enterprise Linux and 21 more 2026-06-29 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-2026-33846 2 Gnu, Redhat 14 Gnutls, Discovery, Enterprise Linux and 11 more 2026-06-29 7.5 High
A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length field remains consistent across all fragments of the same logical message. An attacker can exploit this by sending crafted DTLS fragments with conflicting message_length values, causing the implementation to allocate a buffer based on a smaller initial fragment and subsequently write beyond its bounds using larger, inconsistent fragments. Because the merge operation does not enforce proper bounds checking against the allocated buffer size, this results in an out-of-bounds write on the heap. The vulnerability is remotely exploitable without authentication via the DTLS handshake path and can lead to application crashes or potential memory corruption.
CVE-2026-33845 2 Gnu, Redhat 14 Gnutls, Discovery, Enterprise Linux and 11 more 2026-06-29 7.5 High
A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service.

A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to sensitive data being corrupted in memory.
CVE-2025-49794 1 Redhat 15 Cert Manager, Enterprise Linux, Hummingbird and 12 more 2026-06-29 9.1 Critical
A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the <sch:name path="..."/> schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program's crash using libxml or other possible undefined behaviors.
CVE-2025-9566 1 Redhat 9 Enterprise Linux, Hummingbird, Openshift and 6 more 2026-06-29 8.1 High
There's a vulnerability in podman where an attacker may use the kube play command to overwrite host files when the kube file container a Secrete or a ConfigMap volume mount and such volume contains a symbolic link to a host file path. In a successful attack, the attacker can only control the target file to be overwritten but not the content to be written into the file. Binary-Affected: podman Upstream-version-introduced: v4.0.0 Upstream-version-fixed: v5.6.1
CVE-2025-9900 1 Redhat 10 Ai Inference Server, Discovery, Enterprise Linux and 7 more 2026-06-29 8.8 High
A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.
CVE-2025-7425 1 Redhat 17 Cert Manager, Discovery, Enterprise Linux and 14 more 2026-06-29 7.8 High
A flaw was found in libxslt where the attribute type, atype, flags are modified in a way that corrupts internal memory management. When XSLT functions, such as the key() process, result in tree fragments, this corruption prevents the proper cleanup of ID attributes. As a result, the system may access freed memory, causing crashes or enabling attackers to trigger heap corruption.
CVE-2025-7424 2 Redhat, Xmlsoft 5 Enterprise Linux, Hummingbird, Openshift and 2 more 2026-06-29 7.5 High
A flaw was found in the libxslt library. The same memory field, psvi, is used for both stylesheet and input data, which can lead to type confusion during XML transformations. This vulnerability allows an attacker to crash the application or corrupt memory. In some cases, it may lead to denial of service or unexpected behavior.
CVE-2026-13595 2 Linux, Redhat 6 Util-linux, Enterprise Linux, Hardened Images and 3 more 2026-06-29 6.8 Medium
A flaw was found in the libblkid library of util-linux. During nested partition probing, the BSD, Minix, Solaris x86, and UnixWare partition probers cache a raw pointer to a parent partition entry in a dynamically allocated array. When subsequent partition additions cause the array to be reallocated, this pointer becomes stale, leading to a heap use-after-free read. An attacker who can present a crafted block device image (for example, via USB insertion or a loop-mounted disk image) can trigger this flaw without user interaction, as libblkid is invoked automatically by udev/udisks as root on block-device hot-plug events. This could lead to limited information disclosure or denial of service.
CVE-2026-12912 1 Redhat 2 Enterprise Linux, Hummingbird 2026-06-29 7.3 High
A flaw was found in libtiff. A remote attacker could exploit this vulnerability by providing a specially crafted PixarLog-compressed TIFF image. This issue occurs when decoding Pixarlog codec images with the PIXARLOGDATAFMT_8BITABGR output format and a specific stride value, leading to a heap-based buffer overflow. This could potentially result in arbitrary code execution or a denial of service (DoS).
CVE-2026-13757 1 Redhat 3 Enterprise Linux, Hummingbird, Openshift 2026-06-29 6.2 Medium
A flaw was found in p11-kit. The RPC message attribute parsing functions p11_rpc_message_get_attribute() and p11_rpc_message_get_attribute_array_value() form a mutually-recursive call chain with no recursion depth limit when processing nested CKA_WRAP_TEMPLATE, CKA_UNWRAP_TEMPLATE, and CKA_DERIVE_TEMPLATE attributes. An unauthenticated attacker with local access to the p11-kit RPC Unix domain socket can send a specially crafted request with deeply nested template attributes, causing stack exhaustion and crashing the p11-kit server process and its dependent services.
CVE-2026-9150 3 Opensuse, Red Hat, Redhat 10 Libsolv, Red Hat Satellite 6, Enterprise Linux and 7 more 2026-06-29 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-2026-42015 1 Redhat 13 Discovery, Enterprise Linux, Enterprise Linux Eus and 10 more 2026-06-29 5.3 Medium
A flaw was found in gnutls. An off-by-one error exists in the PKCS#12 bag element bounds check. This vulnerability allows an remote attacker to write past the internal array of a PKCS#12 bag when appending to a bag that already contains 32 elements. This memory corruption could lead to a denial of service (DoS) or potentially other unspecified impacts.
CVE-2026-42014 2 Gnu, Redhat 14 Gnutls, Discovery, Enterprise Linux and 11 more 2026-06-29 6.6 Medium
A flaw was found in GnuTLS. The `gnutls_pkcs11_token_set_pin` function, used for changing the Security Officer PIN, can lead to a use-after-free vulnerability. This occurs when an attacker attempts to change the PIN with a NULL old PIN for a token that lacks a protected authentication path.
CVE-2026-42013 2 Gnu, Redhat 14 Gnutls, Discovery, Enterprise Linux and 11 more 2026-06-29 8.2 High
A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name (SAN) could cause the validation process to incorrectly fall back to checking the Common Name (CN) field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to spoofing or man-in-the-middle attacks.
CVE-2026-42012 2 Gnu, Redhat 14 Gnutls, Discovery, Enterprise Linux and 11 more 2026-06-29 7.1 High
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier (URI) or Service (SRV) Subject Alternative Names (SANs). This could cause the certificate validation process to incorrectly fall back to checking DNS hostnames against the Common Name (CN), potentially allowing the attacker to spoof legitimate services or intercept sensitive information.
CVE-2026-42011 1 Redhat 13 Discovery, Enterprise Linux, Enterprise Linux Eus and 10 more 2026-06-29 7.4 High
A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems.
CVE-2026-5260 2 Gnu, Redhat 14 Gnutls, Discovery, Enterprise Linux and 11 more 2026-06-29 8.2 High
A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS#11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure.
