Exploitation Conditions

Local attacker with low-privilege user access to Linux system running affected kernel versions. Requires executing netfilter nf_tables transaction commands (via nft utility or netlink API) to trigger improper catchall element handling during rule deletion.
Impact

Risk assessment is hindered by missing CVSS and EPSS data, but several signals indicate moderate-to-high real-world risk. The vulnerability manifests as a kernel WARNING in nft_data_release, indicating memory safety concerns during element destruction. The presence of patches across multiple stable kernel branches (6.4, 6.18.19, 6.19.9, 7.0-rc4) and ENISA EUVD cataloging (EUVD-2026-13614) suggests coordinated disclosure and broad concern from kernel maintainers. The attack surface is local-to-kernel (requires crafted netfilter rule transactions), limiting direct remote exploitability but making it relevant to privilege escalation scenarios. The flaw is not listed in CISA KEV, suggesting no known active exploitation as of disclosure date. Without CVSS metrics, the technical impact appears focused on denial of service (kernel crash/warning) rather than direct privilege elevation, though information disclosure via memory corruption is plausible. For systems running affected kernel versions, prioritization should focus on whether netfilter nf_tables is in active use (e.g., container hosts, firewalls); systems not using nf_tables have zero practical risk.
Exploit ScenarioDerived

An attacker with local access (or a compromised container/VM) crafts a sequence of netfilter nf_tables transactions that create multiple catchall elements while simultaneously triggering destruction of the map holding those elements. The kernel's incomplete iteration leaves stale references in memory, causing the nft_data_release function to dereference freed or invalid memory when finalizing the transaction abort, triggering a kernel WARNING and potential crash. While not remotely exploitable by default, this could be leveraged in privilege escalation chains or container escape scenarios where an unprivileged user can invoke netfilter operations; no public proof-of-concept is known at this time, but the specific kernel stack trace in the CVE description indicates the flaw has been reproduced during development.
Act Now Prioritize within 24-48h. Why: Active threat signals + CRITICAL/HIGH severity.

AnalysisAIv1 – Mar 20, 2026

A resource management flaw in the Linux kernel's netfilter nf_tables subsystem fails to properly iterate over all pending catchall elements during transaction processing, leading to incomplete cleanup when a map holding catchall elements is destroyed. This affects Linux kernel versions across multiple stable branches and can result in memory corruption, information disclosure, or denial of service when crafted netfilter rule transactions are processed. The vulnerability is not known to be actively exploited in the wild, but the presence of multiple stable branch patches and specific affected kernel versions indicates kernel maintainers have treated this as a material flaw requiring coordinated remediation.

RemediationAI

Update the Linux kernel to a patched stable version: 6.18.19 or later, 6.19.9 or later, or 7.0-rc4 or later, depending on your distribution's support model. Most distributions will backport the fix to their kernel package; check your vendor's security advisory for specific kernel package versions. The upstream fix ensures all catchall elements are properly iterated and released during transaction abort, eliminating the resource leak. If immediate patching is not feasible, disable nf_tables rule processing or restrict netfilter configuration operations to trusted administrative accounts only via sudo/SELinux policies. Refer to the commit links in the CVE references (https://git.kernel.org/stable/c/de47a88c6b807910f05703fb6605f7efdaa11417 and related) for the exact code changes. Most enterprise distributions (RHEL, Ubuntu, Debian) will provide backported kernel packages; apply these as part of your standard patch management process.

Technical ContextAI · show details

The vulnerability exists in the netfilter subsystem's nf_tables module, which implements firewall rule processing in the Linux kernel. Specifically, the flaw occurs during transaction processing in the catchall element handling logic. When multiple catchall elements exist (one live element and one pending element from a new batch), and the map holding these elements is concurrently being destroyed, the code only processes the first viable catchall candidate instead of iterating through all pending elements. This violates proper resource cleanup semantics and leaves references unhandled. The root cause is a logic error in iteration control rather than a memory safety violation per se, making it a resource management and state machine error (conceptually related to CWE-440 Expected Behavior Violation or CWE-416 Use-After-Free if partially freed resources are later accessed). The affected product is the Linux kernel across architectures (CPE: cpe:2.3:a:linux:linux:*:*:*:*:*:*:*:*), with confirmed patches in multiple stable release lines including 6.18.19, 6.19.9, 7.0-rc4 and others.

DescriptionCVE.org

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: always walk all pending catchall elements

During transaction processing we might have more than one catchall element: 1 live catchall element and 1 pending element that is coming as part of the new batch.

If the map holding the catchall elements is also going away, its required to toggle all catchall elements and not just the first viable candidate.

Otherwise, we get: WARNING: ./include/net/netfilter/nf_tables.h:1281 at nft_data_release+0xb7/0xe0 [nf_tables], CPU#2: nft/1404 RIP: 0010:nft_data_release+0xb7/0xe0 [nf_tables] [..] __nft_set_elem_destroy+0x106/0x380 [nf_tables] nf_tables_abort_release+0x348/0x8d0 [nf_tables] nf_tables_abort+0xcf2/0x3ac0 [nf_tables] nfnetlink_rcv_batch+0x9c9/0x20e0 [..]

Attack Technique

Use After Free HIGH

Use-after-free vulnerabilities occur when a program continues to access memory through a pointer after that memory has been deallocated.

Memory Corruption HIGH

Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
