| CVE-2026-42010 | 2 Gnu, Redhat | 4 Gnutls, Enterprise Linux, Hardened Images and 1 more | 2026-09-15 | 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-2026-42055 | 2 F5, Redhat | 11 Dos, Nginx Gateway Fabric, Nginx Ingress Controller and 8 more | 2026-09-14 | N/A | 8.1 HIGH |
| NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_proxy_v2_module and ngx_http_grpc_module modules. This vulnerability exists when the proxy_http_version to 2 or grpc_pass directives are used to proxy HTTP/2 traffic, the ignore_invalid_headers directive is set to off, and the large_client_header_buffers directive size is larger than 2 megabytes. A remote, unauthenticated attacker, along with conditions beyond their control, could send large headers while creating an upstream request. This may cause a heap-based buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. | |||||
| CVE-2026-3833 | 2 Gnu, Redhat | 4 Gnutls, Enterprise Linux, Hardened Images and 1 more | 2026-09-14 | N/A | 6.5 MEDIUM |
| A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure. | |||||
| CVE-2026-71227 | 2 Redhat, Smuellerdd | 4 Enterprise Linux, Hardened Images, Openshift Container Platform and 1 more | 2026-09-14 | N/A | 5.1 MEDIUM |
| A flaw was found in libkcapi. A local attacker can influence an application that uses the Asynchronous Input/Output (AIO) interface. By reusing an AIO-enabled handle after a prior completion error, the _kcapi_aio_read_all() function can enter a non-terminating wait loop. This can lead to a persistent denial of service, making the affected application or thread unresponsive. | |||||
| CVE-2026-71226 | 2 Redhat, Smuellerdd | 4 Enterprise Linux, Hardened Images, Openshift Container Platform and 1 more | 2026-09-14 | N/A | 7.3 HIGH |
| Memory Corruption via Uncanceled AIO Requests on Error: libkcapi's one-shot AIO path can return an error before all submitted IOCBs are drained, allowing later kernel writes into caller-owned output buffers. | |||||
| CVE-2026-71225 | 2 Redhat, Smuellerdd | 4 Enterprise Linux, Hardened Images, Openshift Container Platform and 1 more | 2026-09-14 | N/A | 6.5 MEDIUM |
| A flaw was found in libkcapi. When performing one-shot symmetric cipher operations on large inputs (over 64 KiB) in stateful modes such as Counter (CTR) or Cipher Block Chaining (CBC), the library improperly reuses the Initialization Vector (IV) for each internal data chunk. A remote attacker could potentially exploit this by making an application that uses libkcapi process specially crafted large inputs. This can lead to a significant weakening of data confidentiality, as the repeated IV use can expose relationships in encrypted plaintext, and may also affect data integrity by causing incorrect cryptographic processing. | |||||
| CVE-2026-5704 | 2 Gnu, Redhat | 3 Tar, Enterprise Linux, Hardened Images | 2026-09-10 | N/A | 5.0 MEDIUM |
| A flaw was found in tar. A remote attacker could exploit this vulnerability by crafting a malicious archive, leading to hidden file injection with fully attacker-controlled content. This bypasses pre-extraction inspection mechanisms, potentially allowing an attacker to introduce malicious files onto a system without detection. | |||||
| CVE-2026-2100 | 2 P11-kit Project, Redhat | 3 P11-kit, Enterprise Linux, Hardened Images | 2026-09-06 | 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-2026-59847 | 2 Libssh, Redhat | 3 Libssh, Enterprise Linux, Hardened Images | 2026-09-04 | N/A | 5.9 MEDIUM |

| CVE-2026-42009 | 2 Gnu, Redhat | 14 Gnutls, Enterprise Linux, Enterprise Linux For Els and 11 more | 2026-09-04 | 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-2026-48864 | 2 Opensuse, Redhat | 6 Libsolv, Enterprise Linux, Hardened Images and 3 more | 2026-09-03 | N/A | 7.8 HIGH |
| A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service. | |||||
| CVE-2026-59850 | 2 Libssh, Redhat | 3 Libssh, Enterprise Linux, Hardened Images | 2026-09-01 | N/A | 4.3 MEDIUM |
