CVE-2022-49566 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
