CVE-2026-23229

  2. Vulnerabilities (CVE)
  3. CVE-2026-23229
In the Linux kernel, the following vulnerability has been resolved: crypto: virtio - Add spinlock protection with virtqueue notification When VM boots with one virtio-crypto PCI device and builtin backend, run openssl benchmark command with multiple processes, such as openssl speed -evp aes-128-cbc -engine afalg -seconds 10 -multi 32 openssl processes will hangup and there is error reported like this: virtio_crypto virtio0: dataq.0:id 3 is not a head! It seems that the data virtqueue need protection when it is handled for virtio done notification. If the spinlock protection is added in virtcrypto_done_task(), openssl benchmark with multiple processes works well.

Summary
  • (es) Se ha resuelto la siguiente vulnerabilidad en el kernel de Linux: crypto: virtio - Añadir protección con spinlock con notificación de virtqueue Cuando una VM arranca con un dispositivo PCI virtio-crypto y un backend integrado, ejecutar el comando de benchmark de OpenSSL con múltiples procesos, como openssl speed -evp aes-128-cbc -engine afalg -seconds 10 -multi 32 los procesos de OpenSSL se colgarán y se reporta un error como este: virtio_crypto virtio0: dataq.0:id 3 is not a head! Parece que el virtqueue de datos necesita protección cuando se maneja para la notificación de finalización de virtio. Si se añade la protección con spinlock en virtcrypto_done_task(), el benchmark de OpenSSL con múltiples procesos funciona correctamente.
