| CVE-2026-4647 | 2 Gnu, Redhat | 3 Binutils, Enterprise Linux, Openshift Container Platform | 2026-09-01 | N/A | 6.1 MEDIUM |
| A flaw was found in the GNU Binutils BFD library, a widely used component for handling binary files such as object files and executables. The issue occurs when processing specially crafted XCOFF object files, where a relocation type value is not properly validated before being used. This can cause the program to read memory outside of intended bounds. As a result, affected tools may crash or expose unintended memory contents, leading to denial-of-service or limited information disclosure risks. | |||||
| CVE-2026-3442 | 2 Gnu, Redhat | 3 Binutils, Enterprise Linux, Openshift Container Platform | 2026-09-01 | N/A | 6.1 MEDIUM |
| A flaw was found in GNU Binutils. This vulnerability, a heap-based buffer overflow, specifically an out-of-bounds read, exists in the bfd linker component. An attacker could exploit this by convincing a user to process a specially crafted malicious XCOFF object file. Successful exploitation may lead to the disclosure of sensitive information or cause the application to crash, resulting in an application level denial of service. | |||||
| CVE-2026-3441 | 2 Gnu, Redhat | 3 Binutils, Enterprise Linux, Openshift Container Platform | 2026-09-01 | N/A | 6.1 MEDIUM |
| A flaw was found in GNU Binutils. This heap-based buffer overflow vulnerability, specifically an out-of-bounds read in the bfd linker, allows an attacker to gain access to sensitive information. By convincing a user to process a specially crafted XCOFF object file, an attacker can trigger this flaw, potentially leading to information disclosure or an application level denial of service. | |||||
| CVE-2025-32990 | 2 Gnu, Redhat | 3 Gnutls, Enterprise Linux, Openshift Container Platform | 2026-09-01 | N/A | 6.5 MEDIUM |
| A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system. | |||||
| CVE-2025-32989 | 2 Gnu, Redhat | 3 Gnutls, Enterprise Linux, Openshift Container Platform | 2026-09-01 | N/A | 5.3 MEDIUM |
| A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly. | |||||
| CVE-2025-32988 | 2 Gnu, Redhat | 3 Gnutls, Enterprise Linux, Openshift Container Platform | 2026-09-01 | N/A | 6.5 MEDIUM |
| A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free condition when the parent function or caller later attempts to free the same structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of service or memory corruption, depending on allocator behavior. | |||||
| CVE-2023-4693 | 2 Gnu, Redhat | 2 Grub2, Enterprise Linux | 2026-07-21 | N/A | 5.3 MEDIUM |
| An out-of-bounds read flaw was found on grub2's NTFS filesystem driver. This issue may allow a physically present attacker to present a specially crafted NTFS file system image to read arbitrary memory locations. A successful attack allows sensitive data cached in memory or EFI variable values to be leaked, presenting a high Confidentiality risk. | |||||
| CVE-2023-4692 | 2 Gnu, Redhat | 2 Grub2, Enterprise Linux | 2026-07-21 | N/A | 7.5 HIGH |
| An out-of-bounds write flaw was found in grub2's NTFS filesystem driver. This issue may allow an attacker to present a specially crafted NTFS filesystem image, leading to grub's heap metadata corruption. In some circumstances, the attack may also corrupt the UEFI firmware heap metadata. As a result, arbitrary code execution and secure boot protection bypass may be achieved. | |||||
| CVE-2023-4806 | 3 Fedoraproject, Gnu, Redhat | 22 Fedora, Glibc, Codeready Linux Builder Eus and 19 more | 2026-07-14 | N/A | 5.9 MEDIUM |
| A flaw has been identified in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags. | |||||
| CVE-2026-6238 | 1 Gnu | 1 Glibc | 2026-07-14 | N/A | 6.5 MEDIUM |
| The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.0.1 to version 2.43 fail to validate the RDATA content against the RDATA length in a DNS response when processing A6, CERT, LOC, TKEY or TSIG records, which may allow an attacker to craft a DNS response, causing a target application to crash or read uninitialized memory. These functions are for application debugging only and hence not in the path of code executed by the DNS resolver. Further, they have been deprecated since version 2.34 and should not be used by any new applications. Applications should consider porting away from these interfaces since they may be removed in future versions. | |||||
| CVE-2026-5928 | 1 Gnu | 1 Glibc | 2026-07-14 | N/A | 7.5 HIGH |
| Calling the ungetwc function on a FILE stream with wide characters encoded in a character set that has overlaps between its single byte and multi-byte character encodings, in the GNU C Library version 2.43 or earlier, may result in an attempt to read bytes before an allocated buffer, potentially resulting in unintentional disclosure of neighboring data in the heap, or a program crash. A bug in the wide character pushback implementation (_IO_wdefault_pbackfail in libio/wgenops.c) causes ungetwc() to operate on the regular character buffer (fp->_IO_read_ptr) instead of the actual wide-stream read pointer (fp->_wide_data->_IO_read_ptr). The program crash may happen in cases where fp->_IO_read_ptr is not initialized and hence points to NULL. The buffer under-read requires a special situation where the input character encoding is such that there are overlaps between single byte representations and multibyte representations in that encoding, resulting in spurious matches. The spurious match case is not possible in the standard Unicode character sets. | |||||
| CVE-2026-5450 | 1 Gnu | 1 Glibc | 2026-07-14 | N/A | 9.8 CRITICAL |
| Calling the scanf family of functions with a %mc (malloc'd character match) in the GNU C Library version 2.7 to version 2.43 with a format width specifier with an explicit width greater than 1024 could result in a one byte heap buffer overflow. | |||||
| CVE-2026-5435 | 1 Gnu | 1 Glibc | 2026-07-14 | N/A | 7.3 HIGH |
| The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.2 and newer fail to enforce the caller-supplied buffer length, and can result in an out-of-bounds write when printing TSIG records. | |||||
| CVE-2026-4438 | 1 Gnu | 1 Glibc | 2026-07-14 | N/A | 5.4 MEDIUM |
| Calling gethostbyaddr or gethostbyaddr_r with a configured nsswitch.conf that specifies the library's DNS backend in the GNU C library version 2.34 to version 2.43 could result in an invalid DNS hostname being returned to the caller in violation of the DNS specification. | |||||
| CVE-2026-4437 | 1 Gnu | 1 Glibc | 2026-07-14 | N/A | 7.5 HIGH |
| Calling gethostbyaddr or gethostbyaddr_r with a configured nsswitch.conf that specifies the library's DNS backend in the GNU C Library version 2.34 to version 2.43 could, with a crafted response from the configured DNS server, result in a violation of the DNS specification that causes the application to treat a non-answer section of the DNS response as a valid answer. | |||||
| CVE-2026-4046 | 1 Gnu | 1 Glibc | 2026-07-14 | N/A | 7.5 HIGH |
| The iconv() function in the GNU C Library versions 2.43 and earlier may crash due to an assertion failure when converting inputs from the IBM1390 or IBM1399 character sets, which may be used to remotely crash an application. This vulnerability can be trivially mitigated by removing the IBM1390 and IBM1399 character sets from systems that do not need them. | |||||
| CVE-2026-3904 | 1 Gnu | 1 Glibc | 2026-07-14 | N/A | 6.2 MEDIUM |
| Calling NSS-backed functions that support caching via nscd may call the nscd client side code and in the GNU C Library version 2.36 under high load on x86_64 systems, the client may call memcmp on inputs that are concurrently modified by other processes or threads and crash. The nscd client in the GNU C Library uses the memcmp function with inputs that may be concurrently modified by another thread, potentially resulting in spurious cache misses, which in itself is not a security issue. However in the GNU C Library version 2.36 an optimized implementation of memcmp was introduced for x86_64 which could crash when invoked with such undefined behaviour, turning this into a potential crash of the nscd client and the application that uses it. This implementation was backported to the 2.35 branch, making the nscd client in that branch vulnerable as well. Subsequently, the fix for this issue was backported to all vulnerable branches in the GNU C Library repository. It is advised that distributions that may have cherry-picked the memcpy SSE2 optimization in their copy of the GNU C Library, also apply the fix to avoid the potential crash in the nscd client. | |||||
