In the Linux kernel, the following vulnerability has been resolved:
crypto: aead,cipher - zeroize key buffer after use
I.G 9.7.B for FIPS 140-3 specifies that variables temporarily holding cryptographic information should be zeroized once they are no longer needed. Accomplish this by using kfree_sensitive for buffers that previously held the private key.
