About this tag
CVE-2026-23395 is a Linux kernel vulnerability in the Bluetooth L2CAP Enhanced Credit-Based Flow Control implementation. The bug allows duplicate L2CAP_ECRED_CONN_REQ messages with the same signaling identifier, which can cause the system to queue more channels than the L2CAP_ECRED_MAX_CID limit, leading to a potential overrun in the l2cap_ecred_rsp_defer function. The fix tightens request validation to reject duplicate in-flight requests. While this is a Linux kernel issue, Windows users and IT professionals should be aware of cross-platform Bluetooth protocol risks and the importance of kernel-level patching for connected devices.

    CVE-2026-23395: Linux Bluetooth L2CAP eCred Fix for Duplicate Identifier Requests

    CVE-2026-23395 is a reminder that some of the most consequential kernel bugs are not dramatic memory-corruption exploits, but protocol-state mistakes that quietly break invariants the code was relying on. In this case, the Linux Bluetooth stack’s L2CAP Enhanced Credit-Based Flow Control path...
