Published severityHighOperational priority:Medium, lowered one band.downgradedsince 5 Aug 2026

Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.13% 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.

24 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
A use-after-free vulnerability was found in the macvlan driver. When creating a macvlan interface in source mode fails after the source MAC has been added to the hash table (e.g., due to an invalid interface name), the hash entry still references the freed net_device structure. Subsequent packets matching that source MAC trigger use-after-free in macvlan_forward_source().
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.

What, why and how

In the Linux kernel, the following vulnerability has been resolved: macvlan: fix error recovery in macvlan_common_newlink() valis provided a nice repro to crash the kernel: ip link add p1 type veth peer p2 ip link set address 00:00:00:00:00:20 dev p1 ip link set up dev p1 ip link set up dev p2 ip link add mv0 link p2 type macvlan mode source ip link add invalid% link p2 type macvlan mode source macaddr add 00:00:00:00:00:20 ping -c1 -I p1 1.2.3.4 He also gave a very detailed analysis: <quote valis> The issue is triggered when a new macvlan link is created with MACVLAN_MODE_SOURCE mode and MACVLAN_MACADDR_ADD (or MACVLAN_MACADDR_SET) parameter, lower device already has a macvlan port and register_netdevice() called from macvlan_common_newlink() fails (e.g. because of the invalid link name). In this case macvlan_hash_add_source is called from macvlan_change_sources() / macvlan_common_newlink(): This adds a reference to vlan to the port's vlan_source_hash using macvlan_source_entry. vlan is a pointer to the priv data of the link that is being created. When register_netdevice() fails, the error is returned from macvlan_newlink() to rtnl_newlink_create(): if (ops->newlink) err = ops->newlink(dev, &params, extack); else err = register_netdevice(dev); if (err < 0) { free_netdev(dev); goto out; } and free_netdev() is called, causing a kvfree() on the struct net_device that is still referenced in the source entry attached to the lower device's macvlan port. Now all packets sent on the macvlan port with a matching source mac address will trigger a use-after-free in macvlan_forward_source(). </quote valis> With all that, my fix is to make sure we call macvlan_flush_sources() regardless of @create value whenever "goto destroy_macvlan_port;" path is taken. Many thanks to valis for following up on this issue.

Why

The program can continue using memory after it has been released, producing unsafe and attacker-influenceable behaviour.

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may disrupt the affected service.

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 → Use After Free → disrupt the affected service
Attack surface
Local
Privileges required
Low: a basic authenticated account is required
User interaction
None
Attack complexity
Low: no specialised conditions are recorded
Security boundary
Unchanged: impact remains within the vulnerable component's security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-416 ↗

CWE-416: Use After Free. The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory belongs to the code that operates on the new pointer.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVLocalAttack vector: The attacker needs local access to the vulnerable system.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRLowPrivileges required: The attacker needs basic user-level privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.AHighAvailability impact: A successful attack can cause a major loss.
Post-exploitation / living off the land
The issue can support a local privilege or sandbox boundary transition; normal system utilities may then be available in the gained context.

JVN iPedia · Japanese · JVNDB-2026-008032LinuxのLinux Kernelにおける解放済みメモリの使用に関する脆弱性

Linuxカーネルにおいて、以下の脆弱性が修正されました：macvlan: macvlan_common_newlink()のエラー復旧に関する修正です。valis氏がカーネルをクラッシュさせる良い再現手順を提供しました。手順は次のとおりです：ip link add p1 type veth peer p2、ip link set address 00:00:00:00:00:20 dev p1、ip link set up dev p1、ip link set up dev p2、ip link add mv0 link p2 type macvlan mode source、ip link add invalid% link p2 type macvlan mode source macaddr add 00:00:00:00:00:20、ping -c1 -I p1 1.2.3.4。また、非常に詳細な解析も提供されました。quote valis 問題は、新しいmacvlanリンクがMACVLAN_MODE_SOURCEモードおよびMACVLAN_MACADDR_ADD（またはMACVLAN_MACADDR_SET）パラメータで作成され、lowerデバイスにすでにmacvlanポートが存在し、macvlan_common_newlink()から呼び出されるregister_netdevice()が失敗した場合（例：無効なリンク名のため）に発生します。この場合、macvlan_change_sources()およびmacvlan_common_newlink()からmacvlan_hash_add_sourceが呼び出されます。これはmacvlan_source_entryを使ってポートのvlan_source_hashにvlanへの参照を追加します。vlanは作成中のリンクのprivデータを指すポインタです。register_netdevice()が失敗すると、そのエラーはmacvlan_newlink()からrtnl_newlink_create()に返されます。if (ops-newlink) err = ops-newlink(dev, &params, extack); else err = register_netdevice(dev); if (err 0) {free_netdev(dev); goto out;} そしてfree_netdev()が呼ばれ、lowerデバイスのmacvlanポートに付けられたsourceエントリでまだ参照されているstruct net_deviceに対してkvfree()が実行されます。その結果、該当するソースMACアドレスを持つmacvlanポート上で送信されるすべてのパケットはmacvlan_forward_source()においてuse-after-freeを引き起こします。/quote valis上記を踏まえ、私の修正では"goto destroy_macvlan_port;"パスが選択された際には@createの値に関係なくmacvlan_flush_sources()を必ず呼び出すようにしました。この問題をフォローアップしてくれたvalis氏に深く感謝しています。
