CVE-2024-42229: crypto: aead,cipher - zeroize key buffer after use
crypto: aeadcipher - zeroize key buffer after use
Other sources
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 kfreesensitive for buffers that previously held the private key.
