UBUNTU-CVE-2026-58010 (CVE-2026-58010)

Details
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.
Severity
6.5 (Medium)
8.2 (High)
N/A (UNKNOWN)

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.

It was discovered that GLib's GDBus authentication mechanism failed to enforce length limitations on data lines read from a client. An unauthenticated attacker could exploit this to cause a denial of service via resource exhaustion. (CVE-2026-15588)
It was discovered that the xdgmime library in GLib had a heap-based buffer overflow. An attacker-controlled MIME magic file could cause an out-of-bounds write on little-endian systems. (CVE-2026-16118)
It was discovered that GLib had an off-by-one error in the GVariant serialiser. An attacker could use this to cause an out-of-bounds read, leading to information disclosure or a denial of service. (CVE-2026-58010)
It was discovered that GLib had an out-of-bounds read in GDateTime. An attacker could use this to corrupt date output and cause a denial of service. (CVE-2026-58011)
It was discovered that GLib's g_regex_replace() function had a buffer over-read when used with the G_REGEX_RAW flag. An attacker could use this to cause information disclosure or a denial of service. (CVE-2026-58012)
It was discovered that GLib's GIOChannel had a buffer over-read when using a custom line terminator. An attacker could use this to cause information disclosure or a denial of service. (CVE-2026-58013)
It was discovered that GLib's GKeyFile had an off-by-one error when loading a key file with an empty value. An attacker could use this to cause an out-of-bounds access or a denial of service. (CVE-2026-58014)
It was discovered that GLib's DBUS_COOKIE_SHA1 authentication mechanism failed to validate the cookie_context parameter. A malicious D-Bus server could use this to read arbitrary files from the client. (CVE-2026-58015)
It was discovered that GLib's D-Bus introspection XML parser had a state confusion issue. An attacker could use this to cause an out-of-bounds read and denial of service. (CVE-2026-58016)

An attacker-controlled MIME magic file could cause an\nout-of-bounds write on little-endian systems. (CVE-2026-16118)\n\nIt was discovered that GLib had an off-by-one error in the GVariant\nserialiser. An attacker could use this to cause an out-of-bounds read,\nleading to information disclosure or a denial of service.\n(CVE-2026-58010)\n\nIt was discovered that GLib had an out-of-bounds read in GDateTime. An\nattacker could use this to corrupt date output and cause a denial of\nservice.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
