CVE-2022-49566

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2022-49566
In the Linux kernel, the following vulnerability has been resolved: crypto: qat - fix memory leak in RSA When an RSA key represented in form 2 (as defined in PKCS #1 V2.1) is used, some components of the private key persist even after the TFM is released. Replace the explicit calls to free the buffers in qat_rsa_exit_tfm() with a call to qat_rsa_clear_ctx() which frees all buffers referenced in the TFM context.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: crypto: qat - reparar pérdida de memoria en RSA Cuando se utiliza una clave RSA representada en formato 2 (como se define en PKCS #1 V2.1), algunos componentes de la clave privada persisten incluso después de que se libere el TFM. Reemplace las llamadas explícitas para liberar los búferes en qat_rsa_exit_tfm() con una llamada a qat_rsa_clear_ctx() que libera todos los búferes a los que se hace referencia en el contexto del TFM.
