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).
Exploitation Probability (EPSS): Low — 0.30% (23th percentile)
Low exploitation probability based on current threat landscape data. Standard patching timeline is appropriate.
