CVE-2026-19499

GNU C Library vulnerabilities

Gravità: High · CVSS 7.7CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:H
Published: Aug 10, 2026, 7:17:30 PM UTC
Source: [NVD] · [CVE record]
EPSS: 0.30% · Oct 22, 2026

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.
