CVE-2026-80846
CVE-2026-80846 is a NULL pointer dereference in the Linux kernel affecting the XFRM ESP-in-TCP path. When queued TCP data is processed after the original ingress device has been removed (e.g., during veth or network namespace teardown), handle_esp() restores skb->dev from the saved skb_iif, bu...

USN-8548-2: Linux kernel vulnerabilities
It was discovered that a logic flaw existed in the XFRM ESP-in-TCP subsystem in the Linux kernel when handling socket buffer fragments. This flaw is known as Fragnesia. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-43503 Several security issues...
USN-8530-2: Linux kernel (HWE) vulnerabilities
It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer operations, collectively known as Dirty Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in the RxRPC networking subsystem when processing paged fragments. A local attacker...

USN-8615-2: Linux kernel (Raspberry Pi) vulnerabilities
It was discovered that a logic flaw existed in the XFRM ESP-in-TCP subsystem in the Linux kernel when handling socket buffer fragments. This flaw is known as Fragnesia. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-43503 Several security issues...
kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel
A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...
