| CVE-2023-4911 | 6 Canonical, Debian, Fedoraproject and 3 more | 40 Ubuntu Linux, Debian Linux, Fedora and 37 more | 2025-07-30 | 7.8 High |
| A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges. | ||||
| CVE-2025-4802 | 2 Gnu, Redhat | 7 Glibc, Discovery, Enterprise Linux and 4 more | 2025-07-26 | 7.8 High |
| Untrusted LD_LIBRARY_PATH environment variable vulnerability in the GNU C Library version 2.27 to 2.38 allows attacker controlled loading of dynamically shared library in statically compiled setuid binaries that call dlopen (including internal dlopen calls after setlocale or calls to NSS functions such as getaddrinfo). | ||||
| CVE-2025-8058 | 1 Gnu | 1 Glibc | 2025-07-25 | 4.2 Medium |
| The regcomp function in the GNU C library version from 2.4 to 2.41 is subject to a double free if some previous allocation fails. It can be accomplished either by a malloc failure or by using an interposed malloc that injects random malloc failures. The double free can allow buffer manipulation depending of how the regex is constructed. This issue affects all architectures and ABIs supported by the GNU C library. | ||||
| CVE-2023-4527 | 4 Fedoraproject, Gnu, Netapp and 1 more | 32 Fedora, Glibc, H300s and 29 more | 2025-06-24 | 6.5 Medium |
| A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash. | ||||
| CVE-2024-33599 | 4 Debian, Gnu, Netapp and 1 more | 20 Debian Linux, Glibc, H300s and 17 more | 2025-06-18 | 8.1 High |
| nscd: Stack-based buffer overflow in netgroup cache If the Name Service Cache Daemon's (nscd) fixed size cache is exhausted by client requests then a subsequent client request for netgroup data may result in a stack-based buffer overflow. This flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary. | ||||
| CVE-2024-33600 | 4 Debian, Gnu, Netapp and 1 more | 27 Debian Linux, Glibc, Active Iq Unified Manager and 24 more | 2025-06-18 | 5.9 Medium |
| nscd: Null pointer crashes after notfound response If the Name Service Cache Daemon's (nscd) cache fails to add a not-found netgroup response to the cache, the client request can result in a null pointer dereference. This flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary. | ||||
| CVE-2024-33601 | 4 Debian, Gnu, Netapp and 1 more | 25 Debian Linux, Glibc, H300s and 22 more | 2025-06-18 | 7.3 High |
| nscd: netgroup cache may terminate daemon on memory allocation failure The Name Service Cache Daemon's (nscd) netgroup cache uses xmalloc or xrealloc and these functions may terminate the process due to a memory allocation failure resulting in a denial of service to the clients. The flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary. | ||||
| CVE-2024-33602 | 4 Debian, Gnu, Netapp and 1 more | 23 Debian Linux, Glibc, Element Software and 20 more | 2025-06-18 | 7.4 High |
| nscd: netgroup cache assumes NSS callback uses in-buffer strings The Name Service Cache Daemon's (nscd) netgroup cache can corrupt memory when the NSS callback does not store all strings in the provided buffer. The flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability is only present in the nscd binary. | ||||
| CVE-2023-6780 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Glibc, Enterprise Linux | 2025-06-17 | 5.3 Medium |
| An integer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when these functions are called with a very long message, leading to an incorrect calculation of the buffer size to store the message, resulting in undefined behavior. This issue affects glibc 2.37 and newer. | ||||
| CVE-2023-6779 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Glibc, Enterprise Linux | 2025-06-13 | 8.2 High |
| An off-by-one heap-based buffer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when these functions are called with a message bigger than INT_MAX bytes, leading to an incorrect calculation of the buffer size to store the message, resulting in an application crash. This issue affects glibc 2.37 and newer. | ||||
| CVE-2021-3326 | 6 Debian, Fujitsu, Gnu and 3 more | 18 Debian Linux, M10-1, M10-1 Firmware and 15 more | 2025-06-09 | 7.5 High |
| The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service. | ||||
| CVE-2020-29562 | 3 Fedoraproject, Gnu, Netapp | 3 Fedora, Glibc, E-series Santricity Os Controller | 2025-06-09 | 4.8 Medium |
| The iconv function in the GNU C Library (aka glibc or libc6) 2.30 to 2.32, when converting UCS4 text containing an irreversible character, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service. | ||||
| CVE-2020-27618 | 5 Debian, Gnu, Netapp and 2 more | 25 Debian Linux, Glibc, 500f and 22 more | 2025-06-09 | 5.5 Medium |
| The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance the input state, which could lead to an infinite loop in applications, resulting in a denial of service, a different vulnerability from CVE-2016-10228. | ||||
| CVE-2019-25013 | 6 Broadcom, Debian, Fedoraproject and 3 more | 12 Fabric Operating System, Debian Linux, Fedora and 9 more | 2025-06-09 | 5.9 Medium |
| The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-byte input sequences in the EUC-KR encoding, may have a buffer over-read. | ||||
| CVE-2021-3998 | 2 Gnu, Netapp | 12 Glibc, H300s, H300s Firmware and 9 more | 2025-06-09 | 7.5 High |
| A flaw was found in glibc. The realpath() function can mistakenly return an unexpected value, potentially leading to information leakage and disclosure of sensitive data. | ||||
| CVE-2021-27645 | 4 Debian, Fedoraproject, Gnu and 1 more | 4 Debian Linux, Fedora, Glibc and 1 more | 2025-06-09 | 2.5 Low |
| The nameserver caching daemon (nscd) in the GNU C Library (aka glibc or libc6) 2.29 through 2.33, when processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in degraded service or Denial of Service on the local system. This is related to netgroupcache.c. | ||||
| CVE-2023-4806 | 3 Fedoraproject, Gnu, Redhat | 24 Fedora, Glibc, Codeready Linux Builder Eus and 21 more | 2025-06-09 | 5.9 Medium |
| A flaw was found 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-2025-5745 | 1 Gnu | 1 Glibc | 2025-06-06 | 5.6 Medium |
| The strncmp implementation optimized for the Power10 processor in the GNU C Library version 2.40 and later writes to vector registers v20 to v31 without saving contents from the caller (those registers are defined as non-volatile registers by the powerpc64le ABI), resulting in overwriting of its contents and potentially altering control flow of the caller, or leaking the input strings to the function to other parts of the program. | ||||
| CVE-2021-38604 | 3 Fedoraproject, Gnu, Oracle | 8 Fedora, Glibc, Communications Cloud Native Core Binding Support Function and 5 more | 2025-05-30 | 7.5 High |
| In librt in the GNU C Library (aka glibc) through 2.34, sysdeps/unix/sysv/linux/mq_notify.c mishandles certain NOTIFY_REMOVED data, leading to a NULL pointer dereference. NOTE: this vulnerability was introduced as a side effect of the CVE-2021-33574 fix. | ||||
| CVE-2022-23219 | 4 Debian, Gnu, Oracle and 1 more | 9 Debian Linux, Glibc, Communications Cloud Native Core Binding Support Function and 6 more | 2025-05-05 | 9.8 Critical |
| The deprecated compatibility function clnt_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its hostname argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution. | ||||
