| Subject: CVE-2024-42229: crypto: aead,cipher - zeroize key buffer after use |
| |
| Description |
| =========== |
| |
| 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. |
| |
| The Linux kernel CVE team has assigned CVE-2024-42229 to this issue. |
| |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
