NVD Description

Note: Versions mentioned in the description apply only to the upstream gcc-14 package and not the gcc-14 package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

A flaw was found in GCC libstdc++. When an application extracts data into a bitset from a wide-character stream, internal stack memory allocation fails to properly account for character size and alignment. An attacker capable of supplying crafted input to an affected application could trigger a stack-based buffer overflow leading denial of service (DoS).
