CVE-2026-45684 (GCVE-0-2026-45684)

Title
OpenTelemetry eBPF Instrumentation: Log enricher writev path can overread and overwrite user buffers
Summary
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.

CVE-2026-5772 (GCVE-0-2026-5772)

Vulnerability from cvelistv5 – Published: 2026-04-09 21:50 – Updated: 2026-04-10 13:52
VLAI
Title
MatchDomainName 1-Byte Stack Buffer Over-Read in Hostname Validation
Summary
A 1-byte stack buffer over-read was identified in the MatchDomainName function (src/internal.c) during wildcard hostname validation when the LEFT_MOST_WILDCARD_ONLY flag is active. If a wildcard * exhausts the entire hostname string, the function reads one byte past the buffer without a bounds check, which could cause a crash.

CVE-2026-58010 (GCVE-0-2026-58010)

Vulnerability from cvelistv5 – Published: 2026-06-30 12:57 – Updated: 2026-06-30 14:28

Title
Glib: buffer over-read in glib/gvariant-serialiser.c via gvs_tuple_is_normal()
Summary
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-2026-58012 (GCVE-0-2026-58012)

Vulnerability from cvelistv5 – Published: 2026-06-30 12:57 – Updated: 2026-06-30 14:38

Title
Glib: buffer over-read in g_regex_replace() via glib/gregex.c:string_append() and g_utf8_next_char()
Summary
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-2026-58013 (GCVE-0-2026-58013)

Vulnerability from cvelistv5 – Published: 2026-06-30 12:57 – Updated: 2026-06-30 15:58

Title
Glib: buffer over-read in glib/giochannel.c via "g_io_channel_read_line_backend"
Summary
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-2026-6238 (GCVE-0-2026-6238)

Vulnerability from cvelistv5 – Published: 2026-04-28 16:43 – Updated: 2026-06-19 20:40

Title
Buffer overread in ns_printrrf with corrupted RDATA field
Summary
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.
