Security readout for executives and security teams
Plain-English summary
CVE-2024-27011 is a Linux kernel nf_tables flaw in transaction abort handling. The source describes a memory leak/refcount issue that can trigger kernel warnings during specific map, element, and set deletion handling. No CVSS score, CWE, or confirmed active exploitation is provided.
Executive priority
Prioritize normal kernel patch management, with higher attention for multi-tenant, security-sensitive, or firewalling systems. Current supplied evidence does not support emergency action based on active exploitation.
Technical view
The bug is in netfilter nf_tables. During an abort path involving delete element plus delete set, mapping refcounts can be restored twice. The kernel fix checks whether the element is inactive in the next generation and skips state restoration when that bit is already cleared.
Likely exposure
Exposure is most likely on Linux systems running affected kernel versions with nf_tables/netfilter present. The bundle lists Linux kernel versions including 4.12 through 6.9-era ranges, but distribution-specific affected and fixed package mapping must come from vendor advisories.
Exploitation context
The provided sources do not state exploitability, required privileges, remote reachability, or public exploit activity. CISA KEV status is false in the bundle. Treat this as an operational kernel maintenance issue unless vendor advisories assign higher urgency for your deployed kernels.
Researcher notes
The record provides root cause and stable commit references but lacks CVSS, CWE, privilege requirements, and exploitability assessment. Avoid assuming remote code execution or privilege escalation without additional vendor or maintainer evidence.
Mitigation direction
- Check your Linux vendor advisory for CVE-2024-27011 applicability.
- Apply kernel updates containing the referenced stable nf_tables fixes.
- For Fedora systems, review the listed Fedora package announcements.
- Reboot into the updated kernel when required by your vendor process.
- Track vendor guidance if no fixed package is available yet.
Validation and detection
- Inventory Linux kernel versions across servers and appliances.
- Map each kernel to vendor advisories for CVE-2024-27011.
- Confirm updated kernels include the referenced stable commits or vendor backports.
- Identify systems using nf_tables or netfilter features.
- Review kernel logs for nf_tables_chain_destroy warnings if investigating symptoms.
