CWE ID 401
Summary
CVE-2022-49566 is a vulnerability affecting the Linux kernel's crypto module. Specifically, it relates to a memory leak issue in the qat driver's RSA implementation. When processing RSA keys in form 2 (as per PKCS #1 V2.1), certain private key components lingered in memory even after the TFM (Trusted File Management) was released. To mitigate this issue, developers have updated qat_rsa_exit_tfm() to call qat_rsa_clear_ctx() instead, which effectively frees all referenced buffers within the TFM context.
