Summary

CVE-2023-52429 is a medium-severity Improper Check for Unusual or Exceptional Conditions (CWE-754) vulnerability in Linux Linux Kernel. Its CVSS base score is 5.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique LSASS Memory (T1003.001); ranked at the 15th 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-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

dm_table_create in drivers/md/dm-table.c in the Linux kernel through 6.7.4 can attempt to (in alloc_targets) allocate more than INT_MAX bytes, and crash, because of a missing check for struct dm_ioctl.target_count.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation explicitly exercises unusual conditions to find missing or incorrect checks.

SI-10 Information Input Validation good match

Input validation directly requires checking for unexpected or malformed conditions before they propagate.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles include structured handling of edge cases and exceptions during design.

SC-6 Resource Availability partial match

Resource quotas and priority allocation limit the system-wide impact of an oversized request.

Secure SDLC practices directly prevent coding flaws that trust unvalidated size values for allocations.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-754, a class-level weakness. Rules are authored against its narrower children: CWE-354.
