About this tag
The tag 'tipc' covers discussions about the Transparent Inter-Process Communication (TIPC) protocol in the Linux kernel, focusing on security vulnerabilities and bug fixes. Recent threads detail several CVEs affecting TIPC, including a deadlock (CVE-2024-0641), a memory leak (CVE-2025-37757), a null-pointer dereference (CVE-2025-38184), and a use-after-free (CVE-2025-40280). These issues can lead to denial of service or kernel memory exhaustion. The content also addresses Microsoft's Azure Linux as a confirmed carrier of the vulnerable code and explains how VEX/CSAF attestations work. Patches have been released upstream and backported by distributors.

    CVE-2024-0641: Linux TIPC deadlock vulnerability and patch overview

    A subtle bug in the Linux kernel’s TIPC subsystem — a double-locking condition in tipc_crypto_key_revoke() — can be driven into a kernel‑level deadlock that lets a local, authenticated user hang or crash a machine. The issue, tracked as CVE‑2024‑0641, is an availability‑only failure (denial of...

    CVE-2025-38184: Azure Linux Carrier of TIPC Bug — Verify Artifacts

    Microsoft’s advisory that Azure Linux is the product Microsoft has identified as shipping the affected library in CVE-2025-38184 is accurate — but it is not a technical guarantee that no other Microsoft product could include the same vulnerable code. The VEX/CSAF attestation Microsoft published...

    CVE-2025-37757 Linux TIPC memory leak fix and Azure Linux attestations

    A new Linux-kernel fix tracked as CVE-2025-37757 closes a straightforward but operationally meaningful bug in the Transparent Inter‑Process Communication (TIPC) transmit path: under backlog pressure the tipc_link_xmit() routine could return -ENOBUFS without purging an skb list, leaking memory...
