connections can outlive their originating easy handles. In OpenSSL 3 provider
configurations, libcurl attaches an allocated library context to the easy
handle's state and passes it to OpenSSL without acquiring an ownership
reference; destroying the easy handle prematurely frees this context while the
active connection retains a dangling pointer, leading to a heap-use-after-free
upon subsequent I/O or post-handshake operations.

| Description | When performing transfers via libcurl’s multi interface, pooled TLS connections can outlive their originating easy handles. In OpenSSL 3 provider configurations, libcurl attaches an allocated library context to the easy handle's state and passes it to OpenSSL without acquiring an ownership reference; destroying the easy handle prematurely frees this context while the active connection retains a dangling pointer, leading to a heap-use-after-free upon subsequent I/O or post-handshake operations. | |
