rxrpc vulnerability

About this tag
The rxrpc vulnerability tag covers a series of Linux kernel security flaws disclosed in May 2026, specifically affecting the RxRPC remote procedure call transport protocol. These include CVE-2026-45988, CVE-2026-46000, CVE-2026-45998, and CVE-2026-31676, which address issues such as partially decrypted packets, packet buffer ownership, use-after-free crashes, and security response handling. While these are Linux-specific vulnerabilities, they are relevant to Windows administrators who manage Linux servers, cloud hosts, container estates, or Windows Subsystem for Linux (WSL) environments. The tag emphasizes the importance of patching obscure kernel subsystems that can become operational security risks in mixed-IT infrastructures.

  1. CVE-2026-45988 RxRPC Linux Kernel Fix: Drop Partially Decrypted Packets

    CVE-2026-45988 is a newly published Linux kernel vulnerability, disclosed by kernel.org and received by NVD on May 27, 2026, that fixes RxRPC handling of partially decrypted RESPONSE packets by discarding failed packets instead of requeuing them for another processing attempt. The short version...

  3. CVE-2026-45998 Linux Kernel RxRPC Fix: No CVSS Yet—Patch Anyway

    CVE-2026-45998 is a newly published Linux kernel vulnerability from kernel.org, added to NVD on May 27, 2026, that fixes a potential use-after-free crash path in the RxRPC networking code when skb_unshare() fails during packet handling. The bug is not yet scored by NVD, and that absence of a...

  4. CVE-2026-31676 RxRPC Linux Kernel Fix: What Windows Admins Should Do

    CVE-2026-31676 is not the kind of Linux kernel flaw that usually generates splashy headlines, but it is exactly the sort of subtle networking bug that security teams should not ignore. The issue sits in RxRPC, a kernel-supported remote procedure call transport used by specialized Linux...
