glibc: Buffer Overflow in strfmon right-justification padding

A flaw was found in glibc. The strfmon and strfmonl functions are vulnerable to a buffer overflow when processing right-justified width padding. This occurs because an incorrect length is used for an internal memory operation, causing data to be written beyond its intended buffer. An attacker cou...

CVE-2026-19499

Calling strfmon and strfmonl 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 strfmonl with right-justified width padding...
