Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.10% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Linux Linux and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Cross-source reconciliation

Remediation availability differs by product scope

Verified remediation exists for at least one product or source, but 20 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Distribution package intelligence

Release-specific package status

Debian, ubuntu findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.

25 package states
Package result overrides the generic status

BlackTree has verified remediation for at least one product or source, but the relevant distribution still reports no fixed package for 20 affected package states shown here. Treat those rows as affected with no fix until that distribution publishes a fixed version.

Repository candidate not checked

A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

Summary
In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: fix race between dump and ip_set_list resize The release path of ip_set_dump_do() and ip_set_dump_done() read inst->ip_set_list via ip_set_ref_netlink(), a plain rcu_dereference_raw() of the array pointer. These run from netlink_recvmsg() without the nfnl mutex and without an RCU read-side critical section. A concurrent ip_set_create() can grow the array: it publishes the new array, calls synchronize_net() and then kvfree()s the old one. Since the dump paths read the array outside any RCU reader, synchronize_net() does not wait for them and the old array can be freed while they still index into it, causing a use-after-free. The dumped set itself stays pinned via set->ref_netlink, so only the array load needs protecting. Take rcu_read_lock() around it, matching ip_set_get_byname() and __ip_set_put_byindex().

Summary
A flaw was found in the Linux kernel's netfilter ipset component. A race condition exists between the `ip_set_list` resize operation and dump operations. This can lead to a use-after-free vulnerability, where memory is accessed after it has been deallocated. A successful exploitation of this flaw could result in a kernel panic, effectively causing a Denial of Service (DoS) on the system.
Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. Red Hat recommends treating all kernel errata as security-relevant. Given the kernel's fundamental role, any bug has a higher chance of impacting system security, even if that impact only becomes clear after a fix is published. Therefore, Red Hat prioritizes delivering fixes that improve our customers' overall security posture. Because of this proactive approach, a patch may be associated with a CVE assignment at a future date. Retroactive CVE assignments are always documented in the corresponding errata and on Red Hat's CVE pages. We strongly advise against delaying updates, as doing so may leave your system exposed when protections are already available.

Why

The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
local access → Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Local
Privileges required
Low: a basic authenticated account is required
User interaction

JVN iPedia · Japanese · JVNDB-2026-027872LinuxのLinux Kernelにおける競合状態に関する脆弱性

Linuxカーネルにおいて、以下の脆弱性が修正されました。netfilter: ipsetにおけるダンプ処理と ip_set_list のリサイズ間の競合状態の修正についてです。ip_set_dump_do() と ip_set_dump_done() のリリース経路は、ip_set_ref_netlink() を介して inst-＞ip_set_list を読み取っています。これは配列ポインタに対する単純な rcu_dereference_raw() です。これらは nfnl ミューテックスなし、RCU 読み取り側のクリティカルセクションなしで netlink_recvmsg() から実行されます。同時に実行される ip_set_create() が配列を拡張する可能性があり、新しい配列を公開した後に synchronize_net() を呼び出し、古い配列を kvfree() で解放します。ダンプパスは RCU リーダー外で配列を読み取るため、synchronize_net() はそれらの終了を待たず、まだ古い配列にアクセスしている間に配列が解放され、使用後解放（Use-after-free）が発生します。ダンプされたセット自体は set-＞ref_netlink によってピン留めされているため、保護が必要なのは配列の読み込みのみです。ip_set_get_byname() と __ip_set_put_byindex() と一致するように、その周囲を rcu_read_lock() で保護しています。BUG: KASAN: slab-use-after-free in ip_set_dump_do (net/netfilter/ipset/ip_set_core.c:1697)アドレス ffff88800b5c4018 のサイズ8の読み取りをタスク exploit/150 が実行しました。コールトレース: ... kasan_report (mm/kasan/report.c:595) ip_set_dump_do (net/netfilter/ipset/ip_set_core.c:1697) netlink_dump (net/netlink/af_netlink.c:2325) netlink_recvmsg (net/netlink/af_netlink.c:1976) sock_recvmsg (net/socket.c:1159) __sys_recvfrom (net/socket.c:2315) ...Oops: ジェネラルプロテクションフォルトが発生しました。非正準アドレスの可能性があります。KASAN NOPTIKASAN: 範囲[0x02d6...d0-0x02d6...d7] でのワイルドメモリアクセスの可能性RIP: 0010:ip_set_dump_do (net/netfilter/ipset/ip_set_core.c:1698)カーネルパニック - 同期せず、致命的な例外が発生しました。
