| CVE-2019-6488 | 1 Gnu | 1 Glibc | 2026-10-14 | N/A |
| The string component in the GNU C Library (aka glibc or libc6) through 2.28, when running on the x32 architecture, incorrectly attempts to use a 64-bit register for size_t in assembly codes, which can lead to a segmentation fault or possibly unspecified other impact, as demonstrated by a crash in __memmove_avx_unaligned_erms in sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S during a memcpy. | ||||
| CVE-2019-19126 | 5 Canonical, Debian, Fedoraproject and 2 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2026-10-14 | 3.3 Low |
| On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program. | ||||
| CVE-2016-10228 | 2 Gnu, Redhat | 2 Glibc, Enterprise Linux | 2026-10-14 | N/A |
| The iconv program in the GNU C Library (aka glibc or libc6) 2.31 and earlier, when invoked with multiple suffixes in the destination encoding (TRANSLATE or IGNORE) along with the -c option, enters an infinite loop when processing invalid multi-byte input sequences, leading to a denial of service. | ||||
| CVE-2026-80489 | 1 Gnu | 1 Glibc | 2026-09-15 | 5.9 Medium |
| Converting crafted EUC_JISX0213 input to UCS-4 or the internal wide character encoding, for example with iconv, in the GNU C Library version 2.3 to 2.44 may result in the converter making no progress, causing the calling application to hang. Some EUC_JISX0213 sequences decode to two code points. If the output buffer has room for only the first one, the converter stores the second in the conversion state and returns E2BIG, but it never clears that pending character after emitting it on the next call. The converter then keeps emitting the pending character without consuming further input, so an application that retries the conversion loops forever. The input must be attacker controlled and the application must convert it with an output buffer small enough to split the two code points. Only the EUC_JISX0213 character set is affected, which is not commonly used. The related defect in SHIFT_JISX0213 converter is tracked separately as CVE-2026-77117. | ||||

| CVE-2026-19542 | 1 Gnu | 1 Glibc | 2026-09-14 | 5.6 Medium |
| Calling tdelete on a sufficiently deep tree in the GNU C Library version 2.1 to 2.44 may write one pointer past the end of an alloca-allocated array on the stack, which may crash the application. The tdelete implementation keeps an explicit stack of parent nodes for rebalancing, which is grown as needed while descending the tree. Two rebalancing branches push an additional entry without checking the capacity, and write past the array when the stack is exactly full. Triggering this requires a node at a depth of exactly 40 (or 40 plus a multiple of 20), which implies a tree with at least a million nodes, so an attacker must drive a large number of insertions and deletions through an application that uses tsearch and tdelete. The written value is a pointer into a tree node and is not directly attacker controlled. No affected application in common distributions has been identified. | ||||
| CVE-2026-19499 | 1 Gnu | 1 Glibc | 2026-09-14 | 7.7 High |
| Calling strfmon and strfmon_l in the GNU C Library version 2.38 to 2.44 can write past the end of the caller-supplied output buffer when a conversion uses right-justified width padding. Exploitation requires an application code path that calls strfmon or strfmon_l with right-justified width padding into a destination buffer that is large enough for the padding to succeed but too small for the internal memmove call. The field width or format may be attacker-influenced or a fixed susceptible pattern in the caller. At the time of publication, no network-facing application impact is known. | ||||
| CVE-2026-6368 | 1 Gnu | 1 Glibc | 2026-08-12 | 5.5 Medium |
| Calling wordexp with WRDE_APPEND in the GNU C Library version 2.0 to version 2.43 can cause the interface to return invalid memory in the we_wordv member, which on subsequent calls to wordfree may abort the process. | ||||
| CVE-2026-6238 | 3 Gnu, Redhat, The Gnu C Library | 3 Glibc, Hummingbird, Glibc | 2026-06-19 | 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-2023-4911 | 7 Canonical, Debian, Fedoraproject and 4 more | 51 Ubuntu Linux, Debian Linux, Fedora and 48 more | 2026-05-12 | 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-2024-33602 | 4 Debian, Gnu, Netapp and 1 more | 23 Debian Linux, Glibc, Element Software and 20 more | 2026-05-12 | 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-2024-33601 | 4 Debian, Gnu, Netapp and 1 more | 27 Debian Linux, Glibc, H300s and 24 more | 2026-05-12 | 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-2024-33600 | 4 Debian, Gnu, Netapp and 1 more | 27 Debian Linux, Glibc, Active Iq Unified Manager and 24 more | 2026-05-12 | 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-2024-33599 | 4 Debian, Gnu, Netapp and 1 more | 20 Debian Linux, Glibc, H300s and 17 more | 2026-05-12 | 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. | ||||
