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 qatrsaexittfm() with a call to qatrsaclearctx() which frees all buffers referenced in the TFM context.
