This flaw is a classic stack or heap buffer overflow (CWE\u2011119) and results in a denial\u2011of\u2011service condition for the affected process.

The EPSS score is under 1\u202f%, indicating a very low likelihood of exploitation in the wild. The vulnerability is not listed in the CISA KEV catalog, and no public exploits have been reported.
