A specially crafted x509 certificate can cause a single out of bounds byte overwrite in wolfSSL through 3.10.2 resulting in potential certificate validation vulnerabilities, denial of service and possible remote code execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
