5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Details

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.
