CVE-2026-72897

A flaw in OpenSSL allows a TLS server to perform an out-of-bounds read or fixed-value out-of-bounds write on the heap when using SSL_set_SSL_CTX() to switch contexts during a handshake. The root cause is that the internal array count for certificate validity flags is not refreshed when the connec...
