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...

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...

CVE-2026-43500

Summary: CVE-2026-43500 affects the Linux kernel RXRPC path for DATA/RESPONSE packets. The issue occurs when skb fragments are externally owned (e.g., via splice() or frag lists) and the code path decrypts in place, binding frag pages into the AEAD/skcipher SGL. The fix extends the gate to unshar...

CVE-2026-43500

A flaw was found in the Linux kernel's RxRPC networking subsystem. When a socket buffer carrying a page-cache reference reaches the RxRPC authentication verification path, the kernel performs an in-place decryption directly on the referenced page without first isolating the buffer. A low-privileg...
