CVE-2026-98690 thunderbolt: Fix domain reference leak when DPRX read is canceled

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Fix domain reference leak when DPRX read is canceled tbtunnelonedp takes a domain reference which is only dropped once tbdptunnelactive has run on the work queue. If that work is cancelled that reference is leaked...

CVE-2026-98690

The Linux kernel contains a vulnerability in the thunderbolt driver where a domain reference is leaked when a DPRX read is canceled. Specifically, the tb_tunnel_one_dp() function takes a reference that is only dropped once; if tb_dp_tunnel_active() work is canceled, the reference remains leaked. ...

CVE-2026-98689

The Linux kernel contains a vulnerability in the thunderbolt component where tb_dp_dprx_work() checks the ->dprx_canceled flag before acquiring the tb->lock. This race condition allows the system to miss a tb_dp_dprx_stop() call, resulting in the kernel polling and running a callback for a ...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.14 contains a security vulnerability. This vulnerability arises from the use of tbdpdprxwork, which checks the dprx Canceled flag before acquiring tb-lock. As a result, running tasks cannot be canceled, leading to the polling of the DPRX capability for the removed DP...
