Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-14087 is a buffer underflow vulnerability (CWE-190) in the GVariant parser of GLib, the core library used in GNOME applications and widely in Linux environments. The flaw causes heap corruption when processing maliciously crafted input strings, potentially leading to denial of service or code execution. It was published on 2025-12-10 with a CVSS v3.1 base score of 5.6 (AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L).
A remote attacker can exploit this vulnerability over the network without requiring privileges or user interaction, though it demands high attack complexity. Exploitation involves feeding specially crafted strings to applications or services that parse GVariant data via GLib, resulting in heap corruption that disrupts service availability or, in some cases, enables arbitrary code execution with the privileges of the affected process.
Red Hat advisories detail mitigation through errata RHSA-2026:7461, which provides updated packages. Further technical details and patches are tracked in the Red Hat CVE page at https://access.redhat.com/security/cve/CVE-2025-14087, Bugzilla entry 2419093, and the upstream GLib issue at https://gitlab.gnome.org/GNOME/glib/-/issues/3834.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (static analysis, fuzzing, unit tests) directly finds integer overflow defects before deployment.
Secure engineering principles require use of safe arithmetic constructs or language features that structurally eliminate integer overflow during calculation.
Input validation enforces bounds on values before arithmetic, stopping the conditions that trigger overflow or wraparound.

Secure SDLC practices directly require use of safe arithmetic, bounds checks, and testing that prevent integer overflows.

Security testing in development can detect integer overflows before release.
Secure SDLC mandates input validation and arithmetic checks that prevent integer overflows.
Application security requirements include bounds checking and safe arithmetic to avoid overflow conditions.
Secure architecture principles require defensive coding patterns that mitigate integer wraparound risks.
Secure coding standards explicitly forbid unsafe integer operations and mandate overflow-safe constructs.
