Description OSIDB Bzimport 2025-02-26 03:12:12 UTC 
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.
