CWE-126 06/07/2026
Buffer Over-read in Windows Compute
Memory Corruption when allocating memory with sizes that exceed the maximum allowed value.
CVE-2026-58013

CWE-126 30/06/2026
Glib: buffer over-read in glib/giochannel.c via "g_io_channel_read_line_backend"
A flaw was found in GLib. A buffer over-read can occur in g_io_channel_read_line_backend() in the giochannel.c file when a custom line terminator with a length greater than one is set, causing memcmp to read past the GString buffer. This vulnerability can cause a minor information disclosure of 7 bytes or a denial of service when the buffer over-read crosses a page boundary.
CVE-2026-58012
Alta · 8.2
CWE-126 30/06/2026
Glib: buffer over-read in g_regex_replace() via glib/gregex.c:string_append() and g_utf8_next_char()
A flaw was found in GLib. A buffer over-read can occur in the g_regex_replace function when used with the `G_REGEX_RAW` compile flag and case-change replacement escapes because the string_append function processes matched substrings using UTF-8 functions that assume valid UTF-8 input, even when the string is treated as raw bytes. This vulnerability can cause a minor information disclosure of 1-5 bytes and a denial of service when the buffer over-read crosses a page boundary.
CVE-2026-58010
Alta · 8.2
CWE-126 30/06/2026
Glib: buffer over-read in glib/gvariant-serialiser.c via gvs_tuple_is_normal()
A flaw was found in GLib. An off-by-one error can occur in the gvs_tuple_is_normal function in the glib/gvariant-serialiser.c file when doing an alignment padding check because the bounds check uses > instead of >=, causing an out-of-bounds read of only 1 byte. This issue can cause a minor information disclosure of 1 byte and a denial of service when the out-of-bounds read crosses a page boundary.
CVE-2026-41992
Alta · 7.5
CWE-126 29/06/2026
Global Buffer Overflow in GNU gzip
GNU gzip contains a global buffer overflow vulnerability in the LZH decompression logic caused by improper reuse of shared global state between different decompression formats within a single execution. GNU gzip maintains a global array that is shared across the LZ77, LZW, and LZH decompression routines and is not reinitialized between files processed in the same invocation.
By decompressing a specially crafted LZW file followed by a specially crafted LZH file in a single gzip -d command, an attacker can poison the shared global state and subsequently trigger an out‑of‑bounds read in the LZH decoder. The LZH decompression logic follows stale values left in the shared array, causing reads past the end of the allocated global buffer.
This issue has been fixed in commits 63dbf6b3b9e6e781df1a6a64e609b10e23969681 and e7378c2d421be6a286922374425680bbe9ad8b7d.

CWE-126 09/06/2026
389-ds-base: 389-ds-base: heap buffer over-read in ldap_utf8prev() via str2simple filter parsing
A flaw was found in 389 Directory Server. The ldap_utf8prev() function reads bytes before the start of a buffer without bounds checking, causing a heap buffer over-read in string filter parsing that may influence internal filter processing behavior.
CVE-2026-44185

CWE-126 08/06/2026
Apache HTTP Server: Stack Buffer Over-Read in mod_ssl OCSP `send_request`
Buffer Over-read vulnerability in Apache HTTP Server via outbound OCSP requests to an attacker controlled OCSP server
This issue affects Apache HTTP Server: from 2.4.0 through 2.4.67.
Users are recommended to upgrade to version 2.4.68, which fixes the issue.
CVE-2026-45684
Média · 5.3
CWE-126 02/06/2026
OpenTelemetry eBPF Instrumentation: Log enricher writev path can overread and overwrite user buffers
OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. From version 0.7.0 to before version 0.9.0, OBI's log enricher mishandles writev buffers by reading only the first iovec entry but using the total iov_iter.count as the copy length. When log injection is enabled, a crafted multi-segment writev call can make OBI read and overwrite memory beyond the first segment. This issue has been patched in version 0.9.0.
