CVE-2022-49566 Information

Description

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.
