Summary

CVE-2024-1048 is a low-severity Incomplete Cleanup (CWE-459) vulnerability in Redhat Enterprise Linux. Its CVSS base score is 3.3 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked at the 18th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-14 (Non-persistence) — see the control section below for these in your framework.

Vulnerability Data

A flaw was found in the grub2-set-bootflag utility of grub2. After the fix of CVE-2019-14865, grub2-set-bootflag will create a temporary file with the new grubenv content and rename it to the original grubenv file. If the program is killed before…

the rename operation, the temporary file will not be removed and may fill the filesystem when invoked multiple times, resulting in a filesystem out of free inodes or blocks.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover incomplete cleanup through dynamic analysis or resource-leak testing.

SI-14 Non-persistence good match

Non-persistence mechanisms explicitly initiate resources in a known state and terminate them, directly enforcing cleanup.

AC-12 Session Termination partial match

Session termination forces explicit release of session-related temporary resources.

SC-4 Information in Shared System Resources partial match

Preventing unintended information transfer through shared resources requires complete cleanup of those resources.

ID.AM-08 partial match
blocks

Life-cycle management encompasses disposal of temporary resources but does not specifically target runtime cleanup bugs.

PR.DS-10 partial match
blocks

Explicitly calls for removing sensitive data after use, directly addressing one class of incomplete cleanup.

PR.PS-06 partial match
blocks

Secure-development practices and coding standards normally require proper resource release and cleanup.
