    🚨HIGH - glibc strfmon/strfmon_l Right-Justified Padding Buffer Overflow (CVE-2026-19499) In GNU C Library (glibc) strfmon/strfmon_l, right-justified width padding can trigger an internal memmove that writes past the caller-provided output buffer when the buffer seems large enough for padding but not for the move. If an attacker can influence the format/field width, this can lead to memory corruption/crash. 👉Affected: glibc 2.38-2.44
