--- title: "CVE-2026-89487\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2026-89487?format=md keywords: index, follow --- # CVE-2026-89487 Publication date 14 September 2026 Last updated 14 September 2026 --- Ubuntu priority **Medium** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description In the Linux kernel, the following vulnerability has been resolved: openvswitch: only skb\_tx\_error() a packet we are about to drop queue\_userspace\_packet() borrows the packet skb -- it only copies it into a private netlink message (user\_skb) and does not own it; on return do\_execute\_actions() keeps forwarding it through the flow's remaining actions. Its error path nevertheless calls skb\_tx\_error(skb), which via skb\_zcopy\_clear() does skb\_shinfo(skb)->flags &= ~SKBFL\_ALL\_ZEROCOPY, stripping SKBFL\_SHARED\_FRAG from that live skb (skb\_tx\_error()'s kerneldoc says "skb must be freed afterwards"). For a MSG\_ZEROCOPY skb carrying page-cache frags, SKBFL\_SHARED\_FRAG is what makes esp\_input() skb\_cow\_data() before in-place AEAD; once it is stripped a later local ESP-in-UDP delivery decrypts in place over pages the sender does not own -- an unprivileged page-cache write (the "Fragnesia" primitive). do\_execute\_actions() ignores output\_userspace()'s return value, so any action after a failed USERSPACE upcall inherits the stripped skb. Move the skb\_tx\_error() to the flow-miss drop path - the "default" branch of ovs\_dp\_process\_packet()'s switch(error), before kfree\_skb(). The call has been here since commit 36d5fe6a0007 ("core, nfqueue, openvswitch: Orphan frags in skb\_zerocopy and handle errors") but was harmless until esp\_input() began relying on SKBFL\_SHARED\_FRAG to gate in-place decrypt; only then did stripping it on a still-forwarded skb become a page-cache write primitive. ## Status Show unmaintained releases | Package | Ubuntu Release |
