Medium severity, CVSS 6.5. EPSS: 0.1% chance of exploitation in the next 30 days.

A flaw was found in DPDK lib/vhost vhost-crypto. Session cleanup can leave a stale cached session pointer, and the data path does not check the session type before attaching it, leading to use-after-free or type confusion in the host vhost-crypto backend.
