CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2024-36031 is a critical-severity Use of a Key Past its Expiration Date (CWE-324) vulnerability in Linux Linux Kernel. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked in the top 48% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to IA-5 (Authenticator Management) and SC-12 (Cryptographic Key Establishment and Management) — see the control section below for these in your framework.

Vulnerability Data
In the Linux kernel, the following vulnerability has been resolved: keys: Fix overwrite of key expiration on instantiation The expiry time of a key is unconditionally overwritten during instantiation, defaulting to turn it permanent. This causes a problem for DNS…

resolution as the expiration set by user-space is overwritten to TIME64_MAX, disabling further DNS updates. Fix this by restoring the condition that key_set_expiry is only called when the pre-parser sets a specific expiry.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
SC-12 requires establishing and managing cryptographic keys including distribution, storage, access and destruction, which directly enforces expiration and rotation policies.
IA-5 requires managing authenticators (including passwords and tokens) with verification, distribution and revocation steps that cover expiration enforcement.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Lifecycle management of cryptographic assets directly includes enforcing key expiration and rotation.

Use-of-cryptography control explicitly covers key lifecycle management including expiration and rotation.
Authentication information policy should mandate key rotation and expiry, directly preventing use of expired keys.
Change-management processes can trigger key rotation, but do not inherently enforce cryptographic expiry rules.
Secure authentication requires cryptographic keys to be replaced before expiry, mitigating the weakness.
