kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...

PT-2026-08: Local Privilege Escalation Vulnerabilities in the Linux Kernel (Dirty Frag)

This security advisory provides information regarding Linux kernel vulnerabilities: CVE-2026-43284 and CVE-2026-43500 , informally known as Dirty Frag. These vulnerabilities allow for local privilege escalation to the superuser root level and affect the Linux kernel modules: esp4 , esp6 and rxrpc...

The vulnerability of the RxRPC module in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the RxRPC module in the Linux operating system’s kernel arises due to improper handling of fragmented packages and mechanisms for copying data into socket buffers. Exploiting this vulnerability allows an attacker to cause service failures...
