CVE-2024-42229 is a medium-severity vulnerability rated 4.1/10 on the CVSS scale. 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.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
