Published severityHighOperational priority:Critical, raised one band.upgradedsince 27 Aug 2026

Evidence used

  • CISA confirms exploitation in the wild.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.71% 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.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs Linux Kernel 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: Within 3 daysRemediation target: Within 90 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
In the Linux kernel, the following vulnerability has been resolved: ipv6: account for fraggap on the paged allocation path In __ip6_append_data(), when the paged-allocation branch is taken (MSG_MORE / NETIF_F_SG / large fraglen), alloclen and pagedlen are computed as alloclen = fragheaderlen + transhdrlen; pagedlen = datalen - transhdrlen; datalen already includes fraggap (datalen = length + fraggap). When fraggap is non-zero, this is not the first skb and transhdrlen is zero. The fraggap bytes carried over from the previous skb are copied just past the fragment headers in the new skb's linear area. The linear area is therefore undersized by fraggap bytes while pagedlen is overstated by the same amount, and the copy writes past skb->end into the trailing skb_shared_info. An unprivileged user can trigger this via a UDPv6 socket using MSG_MORE together with MSG_SPLICE_PAGES. The bad accounting was introduced by commit 773ba4fe9104 ("ipv6: avoid partial copy for zc"). Before commit ce650a166335 ("udp6: Fix __ip6_append_data()'s handling of MSG_SPLICE_PAGES"), the negative copy value caused -EINVAL to be returned. That later commit allowed MSG_SPLICE_PAGES to proceed in this case, making the corruption triggerable. The non-paged branch sets alloclen to fraglen, which already accounts for fraggap because datalen does. Bring the paged branch in line by adding fraggap to alloclen and subtracting it from pagedlen. After this adjustment, copy no longer collapses to -fraggap on the paged path, so remove the stale comment describing that old arithmetic. Since a negative copy is no longer expected for a valid MSG_SPLICE_PAGES case, remove the MSG_SPLICE_PAGES exception from the negative copy check.
Remediation
To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch".

Summary
A flaw was found in the Linux kernel's ipv6 networking subsystem. An incorrect parameter length calculation allows an attacker with permissions to create UDP sockets to trigger overwrites of kernel memory, potentially leading to privilege escalation, data corruption, or a system crash.
Remediation

01

What, why and how

Linux Kernel contains an unspecified vulnerability that can allow for privilege escalation via IPv6 networking subsystem. This vulnerability can impact multiple products, including but not limited to Suse, Red Hat, and other products using Linux.

What

Linux Kernel contains an unspecified vulnerability that can allow for privilege escalation via IPv6 networking subsystem. This vulnerability can impact multiple products, including but not limited to Suse, Red Hat, and other products using Linux.

Why

A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

How

An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may gain additional privileges.

ENISA EUVD · EUVD-2026-41669Known-exploited evidence recorded

In the Linux kernel, the following vulnerability has been resolved: ipv6: account for fraggap on the paged allocation path In __ip6_append_data(), when the paged-allocation branch is taken (MSG_MORE / NETIF_F_SG / large fraglen), alloclen and pagedlen are computed as alloclen = fragheaderlen + transhdrlen; pagedlen = datalen - transhdrlen; datalen already includes fraggap (datalen = length + fraggap). When fraggap is non-zero, this is not the first skb and transhdrlen is zero. The fraggap bytes carried over from the previous skb are copied just past the fragment headers in the new skb's linear area. The linear area is therefore undersized by fraggap bytes while pagedlen is overstated by the same amount, and the copy writes past skb->end into the trailing skb_shared_info. An unprivileged user can trigger this via a UDPv6 socket using MSG_MORE together with MSG_SPLICE_PAGES. The bad accounting was introduced by commit 773ba4fe9104 ("ipv6: avoid partial copy for zc"). Before commit ce650a166335 ("udp6: Fix __ip6_append_data()'s handling of MSG_SPLICE_PAGES"), the negative copy value caused -EINVAL to be returned. That later commit allowed MSG_SPLICE_PAGES to proceed in this case, making the corruption triggerable. The non-paged branch sets alloclen to fraglen, which already accounts for fraggap because datalen does. Bring the paged branch in line by adding fraggap to alloclen and subtracting it from pagedlen. After this adjustment, copy no longer collapses to -fraggap on the paged path, so remove the stale comment describing that old arithmetic. Since a negative copy is no longer expected for a valid MSG_SPLICE_PAGES case, remove the MSG_SPLICE_PAGES exception from the negative copy check.

JVN iPedia · Japanese · JVNDB-2026-024875LinuxのLinux Kernelにおける不特定の脆弱性

Linuxカーネルにおいて、以下の脆弱性が修正されました。ipv6: ページ化割り当てパス上のfraggapを考慮する__ip6_append_data()関数内で、ページ化割り当ての分岐が選択された場合(MSG_MORE / NETIF_F_SG / 大きなfraglen)、alloclenとpagedlenは以下のように計算されます。alloclen = fragheaderlen + transhdrlen; pagedlen = datalen - transhdrlen。datalenは既にfraggapを含んでいます(datalen = length + fraggap)。fraggapがゼロでない場合、このデータは最初のskbのものではなく、transhdrlenはゼロになります。前のskbから持ち越されたfraggapバイトは、新しいskbの線形領域にあるフラグメントヘッダーの直後にコピーされます。そのため、線形領域はfraggapバイト分だけ不足し、pagedlenは同じ分だけ過大に計算されており、このコピー処理がskb->endを超えてskb_shared_infoの末尾部分に書き込む原因となっていました。権限のないユーザーは、MSG_MOREとMSG_SPLICE_PAGESを組み合わせたUDPv6ソケットを用いることで、この脆弱性をトリガーできます。この不適切な計算はコミット773ba4fe9104("ipv6: avoid partial copy for zc")で導入されました。その前のコミットce650a166335("udp6: Fix __ip6_append_data()'s handling of MSG_SPLICE_PAGES")までは、負のコピー値が -EINVAL を返していました。しかし、その後のコミットでMSG_SPLICE_PAGESがこの状態でも進行可能となり、データ破損が引き起こされるようになりました。ページ化されない分岐では、alloclenはfraglenに設定されており、これは既にfraggapを含むdatalenを考慮しています。今回の修正により、ページ化分岐も同様にalloclenにfraggapを加え、pagedlenからfraggapを減じる形で調整されました。この調整後、ページ化パスのコピーサイズが -fraggap になることはなくなり、古い計算を説明するコメントは削除されました。正当なMSG_SPLICE_PAGESケースにおける負のコピーは想定されなくなったため、負のコピー値チェックからMSG_SPLICE_PAGES例外も削除されました。
